Can you give us a extra detailed technical explanation or what happens when a node connects to the Invisible IRC network and the crypto occurring?

To bootstrap into the network every node has these settings: host port protocol = crypt:raw public key = with a 1024-bit (default) Diffie-Hellman public key.

What happens then, using Yarrow pseudo random number generator (http://www.counterpane.com/yarrow.html ) it selects a node to connect to (the extra nodes in your routing desk the better). Then it handshakes with the general public key to that node, and in addition in your node.ref is a community id = 1024 bit, public key = as nicely this sits on the Invisible ircd server (localhost as effectively) and is the top-to-finish key that provides authentication and also secures your communication end-to-finish.

I'm going to describe subsequent what's implemented as of RC2. Now from this point once you've authenticated you've got another step.

Upon every session the user also creates a short lived 2048-bit Diffie-Hellman key to handshake with, for finish to finish as well, and is securely deleted from reminiscence and swap when the session has completed. This is finished because the final step once authenticated.

The explanation for that is that if one were to play spy node and log your session they can not find the IRCD server operator and resolve that his community id key would give them the jewels of the kingdom. It won't, because no one has the 2048-bit temporary session key set that was established upon the irc session. This covers using the asymmetric crypto (Diffie-Hellman and buddies).

Now for symmetric session encryption: We are utilizing 128-bit blowfish for node-to-node and end-to-finish as much as authentication. Then with the non permanent key set we are utilizing a 160-bit session key generated from a SHA-1 hash of the key trade of the 2048-bit DH key.

This ensures the randomness of the key generated, as that's the most important key of all. Also for additional safety now we have the RKA (one thing we got here up with, and I'll explain in a second), as well as utilizing Cipher Block Chaining.

We also have faux traffic 'chaffe' that is randomly generated, despatched out as traffic padding as to cover node activity from site visitors evaluation and sniffers.

So, a node is always trying lively in a roundabout way, messages can't be confirmed to be coming from your node particularly, since messages are coming from each node and there is no such thing as a solution to know what's an actual message and what is the faux visitors.

RKA is the Rotating Key Algorithm. The spurt of faux visitors aids RKA. What this is, is every fifty two blocks (blocks == 64 bit encryption blocks, aka messages) we rotate the session key with random information from the previous session.

With the pretend messaging pushing out blocks. This averages to be about every 10-20 seconds. In the future we may have an eight key set (right now it is about at 1, but is well modified in the code to do as many as you want, this can be carried out as we update our multi-precision library to be faster) which what that will do is generate eight keys to make use of and then xor these eight keys into themselves generating another set of 8 keys.

Eight keys is outlined as 128-bit keys for node to node and 160-bit for end-to-end. This would require eight keys for roughly every 2 minutes of information. So 2 minutes of information cracking clever would have to be eight * 160-bit keys + eight * 128-bit keys, plus it's important to capture all information from the start of session to attain this or it's possible you'll as effectively cease right now.

Plus utilizing CBC we have xor'd every 64-bit block with the last block so typing 'ABCD' the first time won't be the identical ciphertext as 'ABCD' the subsequent time.

As we implement the new multi-precision library our key bit sizes will be much greater and our encryption algorithms will also be user selectable. As an illustration you possibly can select to use AES, blowfish or TwoFish, and so on.

You used the terms finish-to-end and node-to-node encryption. What constitutes a "node" and an "end"?

A "node" is anybody connecting into the IIP network. Each node in this context is isproxy software operating on the node which also offers relay service.

Take a look at it this fashion, a "node" connects to another "node", literally. The two computers running isproxy have established a communication stream beneath the defined encryption protocol, thus "node to node" encryption.

Okay, so node to note means my node, to the node that I'm related to every handling its own crypto, then from that node to the next in the same approach, and so on.

Yes. Now the "finish" is our community server, hidden within the muck of all this. Somewhere down the line you get to satisfy it by connecting in.

That is the communication between you and the server straight. So on this case "end-to-finish" refers back to the communications tunnel out of your node all the way in which by to the "end" - the server working the IRCD. Thus "end-to-end" encryption.

Okay, and on this case, the "end-to-end" means basically another set of crypto that's from my finish (node) to the precise ircd server?

Yes. That is the first layer. Together, the "node-to-node" and "end-to-finish" encryption truly creates two layers (three actually) but we'll get to that later.

Node-to-node and end-to-end encryption appears to be clear to us. Does IIP at the moment have consumer-to-consumer (P2P) non-public message encryption or channel encryption?

At this time no. That is in the works with the decentralized model.

Well, let me clarify that a bit of extra, the way it sounds is that there's encryption occurring on the node-to-node and end-to-end, however all IRC messages, personal and channel are plaintext on the IRCD server, is this appropriate?

No, not precisely. Everything is plaintext at any end-level, just as what you see in your IRC shopper is plaintext.

However the ircd server is sitting on a localhost port, similar to your node is (accessed through a localhost port) which suggests it is unsniffable.

IRC personal messages are actually private and cannot be intercepted or monitored, and channels that are invite solely or locked are non-public as well. At the ircd server if an evil sysop select to, may stay log this and understand the communication - simply as much as you possibly can reside log one thing in your end on your conversations.

However, and this is crucial - logging if it were to be completed does not pinpoint who the heck that particular person is, so if you happen to logged in your node finish or it was completed on the ircd it still wouldn't give out a lot information, aside from the fact that one thing was stated. Not who stated it, or where they're.

Now, we don't log our servers and you'll must belief me on that right now. We have enabled further crypto to prevent logging relays and so attacking the server and replaying the messages is not going to work.

Sooner or later for important true privateness we plan to implement consumer-to-person (P2P) authentication and channel encryption.

So personal messages can't be intercepted by the ircd operator even now?

Technically provided that stay logging is enabled, not by sniffing or anything. In the supply code of the ircd we use we have now disabled the flexibility to log, and also you can't sniff the connection in plaintext. This continues to be using finish-to-finish expertise at the relay layer, simply not decentralization yet.

Okay, you stated technically provided that live logging is enabled in the ircd. We will have to trust you on that. For now, these of us that know you might have a stage of trust in you, but this underscores the necessity for a real IIP decentralized implementation as you say.

In this future system, what happens after we connect our IRC shopper to the proxy we are running?

The design is if you connect your irc client to the iip proxy you'll have "tricked" your irc consumer into thinking it is speaking to an ircd server. Reality is it's not. It's talking to a protocol interpreter, a center man as you'd say, between the irc shopper and the iip protocol.

This future system seems like this: User client --> virc --> iip protocol --> community

The current system appears to be like like this: User shopper --> iip proxy localhost pipe --> iip protocol magic encryption does it's stuff --> network

Sooner or later the virc would be the what's now the localhost pipe, as it's going to emulate all wanted responses to and from the irc shopper. The virc will even have a terminal where you possibly can /msg isproxy and it'll carry you to a terminal sort menu in a personal message box where you'll be able to change settings, set up your individual routes, choose encryption algorithms, regulate the visitors padding options etc. You can even arrange your individual channels and extra.

Now I will give a general layout of what the network will appear to be. Not a too technical format that would take perpetually.

Optional clear textual content channels (normally public channels) can be there, similar to normal irc. You'll have keyspace channels which will be most probably hashes of some sort or public keys. Users will be part of these channels through invite or phrase of mouth as they are privately controlled channels.

Now on the network every channel is treated like a network, an area of your own that you are able to do what with, run whatever transport brokers (webservers, for one example) and so on.

The decentralization will help and improve the routing of the network, as we are able to use a unfold spectrum kind routing method to ship messages down multiple pipes including super confusion to any visitors analysis that could be operating we shall be improving all traffic chaffe and padding decentralization will allow us to take action far more. The network will all the time be shifting and redundancy will be optimal.

It will likely be a "living, respiration, self-sustained community" that users can adopt and dwell on if they would want, providing the ultimate in invisibility, privacy, safety, anonymity, and communication. It isn't an easy activity, and it's an enormous project however you might have my phrase, I do not deliver vaporware, and i refuse to.

Utilizing this protocol, and with the modular code now we have designed you also will be capable of interchange and slot in other protocols (routing and the like) proper into the proxy. Say you want also high volume, static content as well (distributed file sharing system), will probably be very simple.

This may outline the epitome of the Internet when we're finished which I don't think we'll ever be performed because it's always up for improvements, but that is what we like.

On the subject of Peer 2 Peer safety: Utilizing invisibility and anonymity to protect safety. Our standards need to be raised. I believe Invisible IRC Project's aim in the security utility and protocol subject, will hopefully do that, and educate many via the process.

Wow, this is very thought scary stuff. Considered one of the reasons we wanted to do that interview is because we have been aware of a few of these ideas, as some of them had been mentioned in the CODECON speech you gave earlier this year, and likewise among the talk on Invisible IRC Project/IRC #channels.

Yes. There is an mp3 file and .txt transcript of that presentation at CodeCon 2002 obtainable from the Invisible IRC Project web site. I additionally will likely be speaking at ToorCon in September.

Okay, let's speak about authentication of identification subsequent.

We know we're nameless, however currently what measures are in place that can assist ensure that I am really talking to nop or my different associates on IIP?

At the moment we've Trent, which can also be in very beginning stages. He's our authorization agent and you'll register your IRC nick, similar to chanserv. Unfortunately it uses symmetric passwords. We plan to make it a public key server.

Users will generate a public key and be user@publickeyid. This shall be a challenge response authentication system using public key digital signatures.

Where is Trent? Is it part of the ircd? is it an IRC Bot?

It is an IRC service that is operated by a third get together volunteer on IIP. The database is encrypted and hashed, and the third celebration volunteer is a distinguished member and developer of IIP.

[Editors observe: The identify 'Trent' comes from conventional cryptographic literature. In these texts, the authors customarily use the identical set of individuals for example their examples when describing cryptographic protocols. Alice is traditionally the first participant in the protocol being described, Bob is the second. Eve is all the time the sneaky eavesdropper, and Mallory Malicious is all the time solid because the lively snooper who makes an attempt to discover the secret messages through cryptographic assaults. Trent is thought as the Trusted Arbitrator in protocols which require such a celebration.]

If Trent were to maneuver from passwords to a public key system, why would we want Trent? It seems like the authentication system using a public key system is similar to a PGP system. With that being the case, wouldn't we'd each individually be our own Trent, and assign belief to the keys we all know and change? Using a PGP Web of Trust system for key verification?

Yes you can be. Trent is our resolution for the current centralized system. Once we decentralize, the virc will handle all of that.

Okay, so if all of us had our own Trent managing public keys of different users, it seems like that is integral to P2P encrypted messaging, since we'd have a public key infrastructure in place, and keys to encrypt messages to (as per PGP).

This makes numerous sense. Two birds killed with one stone. (I guess that is 3 birds.) Identical to PGP helps with encryption, authentication to (valid public key of recipient) and authentication from (signing of messages with our keys additionally).

Yes.

Channel Encryption is outlined as being able to have a standard IRC Channel, where only sure recipients are able to read the messages of the channel.

So even when someone joined the channel, they wouldn't be ready to know the conversation. Consider it as PGP-secured group conferencing. There are two methods this could be usually achieved I'd suppose:

1) Every message despatched to the channel is encrypted to every channel member's public key (very costly in CPU cycles).

2) Give the channel its own keypair, and share that with all of the users.

Well there are different methods. Channel keypair is the most likely method, however there are ways of of doing it the place a userid can be included within the checklist of authenticating customers which are allowed to handshake with this key.

So if you are trusted for the channel you'll handshake and negotiate a session key for the channel. Each user in turn can have totally different session keys and the channels shall be outlined as finish factors so this might secure finish-to-end encryption, from person to channel.

You would have a list of allowed keys that you'll set your channel with in order you invite individuals the /invite command would auto tag that to the channel key these keys would rotate more than likely each week as really useful. In this occasion, the CPU cycle will not be intensive because like PGP you are just using that for encrypting and calculating the session keys which as soon as established, is trivial on CPU cycles.

Will channel encryption be implemented as an add-on so to speak, to the normal P2P messaging encryption? Or does it belong someplace else?

It will be a major important part of the network there might be non-encrypted channels, also known as public channels, like I consider #nameless may most certainly be non-encrypted. or... presumably encrypted but allowing all keys.

So we may simply encrypt all channels with some having an auth mode and some are just plain public. Then you simply handle the session as customers be a part of the channel. These modes can simply be established. We will be taking a function request list soon.

In your early-2002 CodeCon speech, you talked about that the P2P public key system can be run as a separate consumer utility, and in a roundabout way in the Invisible IRC Project isproxy that customers run.

For the present centralized IRCD model, that's the only way to this point, however when decentralized, we plan to implement that as all a part of the isproxy.

Aha. Perfect. Okay, I see we are mixing some concepts from the current implementation and the long run.

Yes. Channel encryption is future. You have got to recollect centralization has limits. We have to decentralize to ensure that the total onslaught of the IIP imaginative and prescient to be able to occur.

On the IIP Internet site, and in a number of the documentation, we read something about IIP not being restricted to IRC however that you've got efficiently run assessments of an IIP network running Shoutcast mp3 streaming over the iip protocol? Can you tell us about this?

Yes. The text might need been misconstrued from what I was saying, but IIP can handle arbitrary Persistent TCP connections.

Presently you may put any server and any client on it that has a TCP port open and maintains a consistent reference to the client throughout a session.

We are primarily growing a safe and anonymous P2P transport protocol. Transparent thoughts you. That's key.

This is fascinating, so it suggests that the current isproxy that we're all working on our programs truly has no IRC particular protocol hooks in it, or no?

Correct, it has no specifics to IRC, but it surely has specifics for a persistent connection from level A to level B. Also there is the NodeSend pipe that will securely send you the dynamic routing table.

What number of end connections from level A to C (end) does the isproxy at present handle? Meaning point A to B and level A to C. B and C being two separate networks and finish points throughout the Invisible IRC Project.

Yes. You'll be able to do this however you've got to inform your isproxy shopper which network you would like to be on. Now we have (in RC2 particularly) in the node.ref routing table: networkname and networkversion choices (in addition to networkid and networkprotocol).

This will permit by alternative multiple connections, or (what we actually designed it for) was use with upgrades on networks or to have optionally your pals IIP community after which the primary one and you could tell IIP which to connect to or two randomly connect with both one.

Can you connect to each networks at the same time? More than one at the identical time?

Right now no. You can technically within the sense of getting the isproxy course of run twice or your IRC shopper operating twice with new instructions but probably not.

Okay, for proper now IIP has a fixed endpoint, the IRCD in its current configuration.

Yes. This is short-term, but the most viable resolution in a semi-centralized atmosphere.

Is it possible to take the IIP net system as it is, and swap out the ircd with an HTTP internet server?

HTTP web server relying on persistent connections at the moment, no, however with a little bit modification, sure.

Mostly by taking out the delay protocols and a couple of other issues. So, sure, it would be potential, and we've got future plans in this space of course.

One of the frequent asked questions by avid IRC customers is how they will send files to different IRC customers with the IRC protocols DCC and CTCP. Can you quickly explain to our readers what DCC and CTCP are and if they work in IIP?

DCC can be Direct Client Connections and CTCP is Client to Client protocol. In the centralized model of IRC DCC must request the IP deal with on each sides as well as CTCP activity. Being DCC makes use of CTCP for the request the main drawback we saw, right off the bat, was obviously our aim is anonymity and privateness and DCC is immediately not that.

In the decentralized version the plans are to be able to assist this with the implementation of a Freenet protocol for exchange of recordsdata, this may take us a step in direction of Invisible Internet Protocol.

So file transfers to different customers on IIP could be initiated on IIP, but would use the Freenet system to actually perform the sending and receiving by the opposite social gathering?

Yes. Utilizing the dynamic content to level to the static content material IIP --> Freenet --> IIP ack file sent.

Would customers have to be working a neighborhood Freenet node to ship and receive files?

No. We plan to implement it in the IIP protocol. ANSI C is a nicer language to do this in and is less of a useful resource hog than Java and is, in fact, our optimum language.

Well, 0x90, thank you so much for the several hours you took out of your time to reply some of our questions and tell us more about what is occurring with the Invisible IRC Project.

Many of us at Distributed City want to thank you and your group for the good work you could have carried out to this point. We had been in search of a secure chat resolution for our group, and since we noticed the Invisible IRC Project and skilled it, many people use it daily, and conduct fairly a bit of business on it.

We stay up for the way forward for IIP, and hope we will proceed to contribute in various ways in which we will, to further these ideas and technologies.
