The AES is the only required algorithm. The protocol specification also lists optional algorithms like Twofish, CAST, etc., and you can negotiate other algorithms as well during the SILC key exchange protocol, if needed.

The required public key algorithm is RSA, but optional support is for DSS. The RSA algorithm in SILC supports PKCS#1 standard. During the key exchange protocol also Diffie-Hellman public key algorithm is used to exchange keys. The Diffie-Hellman in SILC supports PKCS#3 standard. Adding support for other algorithms like El Gamal is possible by negotiating them in SILC key exchange. PGP keys, or as they are officially called OpenPGP certificates are supported in SILC protocol.

The required encryption mode currently is CBC with inter-packet chaining. The specification recommends implementations to use CTR mode as well, and defines randomized CBC (with random IV's) as optional mode. It is also possible to negotiate other modes during SILC key exchange protocol, if needed. We have also looked into so called authenticated encryption modes that NIST are currently considering. More information will follow later.

The required hash function is SHA-1, but also the MD5 is added to the specification as optional hash function. The SHA-1 is also the required hash function when used as part of HMAC to provide integrity protection for encrypted packets.

There are seven kinds of algorithm available, including: Fix, Round Robin, Weighted Round Robin, Dynamic by Upstream Traffic, Dynamic by Downstream, and Dynamic by Total Traffic and Dynamic by Connection.

By presence we mean indication of presence in the network, and SILC supports several different kinds of presence modes. They can be changed with the UMODE command which changes your user mode in the network. Currently there are the following modes for presence: GONE (I'm away), INDISPOSED (I cannot be here), BUSY (I'm busy, don't bother me), PAGE (page me if you want to talk), and HYPER (I'm hyper active, talk to me). When mode is not set it means you are present in the network.

The SILC was developed by Pekka Riikonen in Finland. He also started the SILC project that now coordinates the SILC development. He has worked for years in the field of security, for example several years at the SSH Communications Security Corporation as Chief Engineer with responsibilities in IPSEC core development. The SILC Project consists of several volunteers who maintain the SILC Network, its routers and servers. Volunteers who provide the silcnet.

SILC stands for Secure Internet Live Conferencing. SILC is very much the same as IRC with the major difference being that all conversations are encrypted and much more secure then IRC. Wikipedia on SILC

The word algorithm is a part of your children’s working vocabulary when they use the Everyday Mathematics program. An algorithm is a set of rules or well-defined procedure guaranteed to achieve a certain objective. For example, following the directions for assembling a new toy for your child, using a recipe, and following any procedure are all examples of algorithms. In mathematics, an algorithm is a recipe for computation.

Yes you can. DScaler is being developped mainly by people using it as an analog source scaler for their projector and they prefer for sure using DScaler from their remote on the sofa rather than from their desk ;-) DScaler is thus filled with keyboard shortcuts for all main options so that you can do everything quickly. We also suggest the use of Girder from Ron Bessems as the application of choice for remote controlling your computer. An export group has been developped. Download it here.

The SILC server is available for free download from the silcnet.org web page. We are not aware of any other SILC server implementations, so far.

SILC Toolkit is a package intended for software developers who would like to develope their own SILC based applications or help in the development of the SILC. The Toolkit includes SILC Protocol Core library, SILC Crypto library, SILC Key Exchange (SKE) library, SILC Math library, SILC Modules (SIM) library, SILC Utility library, SILC Client library and few other libraries.

The official SILC client is available for free download from the silcnet.org web page. There are also several independent projects working with the SILC Toolkit to come up with various other clients, mostly GUI clients. See our links page for links to other clients.

Question that is justified no doubt of that. SILC was not started to become a replacement for IRC. SILC was something that didn't exist in 1996 or even today except that SILC is now released. However, I did check out the IRC3 project in 1997 when I started coding and planning the SILC protocol. But, IRC3 is problematic. Why? Because it still doesn't exist. The project is almost at the same spot where it was in 1997 when I checked it out. And it was old project back then as well.

Most work with genetic algorithms simulates evolution, not learning during an individual's life, and because of this is very different from work in RL. That having been said, there are two provisos. First, there is a large body of work on classifier systems that uses or is closely related to genetic algorithms. This work is concerned with learning during a single agent's lifetime (using GAs to organize the components of the agent's mind) and is in fact RL research.

Contrary to what many other SEO's have recommended over the years and their countless discussions on this topic, we have successfully determined, practiced and shared an effective optimization strategy that has prevailed where others have failed.

For decades, all American school children have been taught one standard procedure for each of the four basic operations of arithmetic. These "standard" algorithms, like the regrouping ("borrowing") algorithm for multi-digit subtraction and the long division algorithm, are not the only way to perform these operations. There are many alternative algorithms taught in other countries. Compared to the standard U.S.

Yes. Two papers have been written. The first paper (Moody, E. G., M. D. King, S. Platnick, C. B. Schaaf, and F. Gao, 2005: Spatially complete global spectral surface albedos: Value-added datasets derived from Terra MODIS land products. IEEE Transactions on Geoscience and Remote Sensing, Vol. 43, 144-158) describes the temporal interpolation technique, data available, and provides error analysis.

Encryption algorithms are mathematical formulas that are used to transform a readable message to a message that can only be read by the intended recipient. In this encryption method the information is encrypted so that only the intended recipient is able to read and transform the message. The message can be intercepted, but it is useless to a person, who cannot decrypt it. Encryption and decryption of the information requires, in addition to the encryption algorithm, a key.

It gives feedback to other MPEG-4 subgroups on the complexity of some functionality. Functions with high complexity are encouraged to be simplified (e.g. simplification of the padding - see [M1097, M1490, M1578, M1814, M2039, M2129, M3572])

The best overview I know of on this topic can be found in the comp.compression FAQ. You can find the comp.compression FAQ via a link on my FAQ, follow the links from my home page. comp.compression and comp.compression.research sometimes will turn up answers to questions regarding specific techniques, but the murkiness of patent law makes it hard to trust *any* source of information.

The topology of the SILC network includes SILC routers and the SILC servers (and SILC clients of course). Normal SILC server does not have direct connections with other SILC servers. They connect directly to the SILC router. SILC Routers may have several server connections and they may connect to several SILC routers. The SILC routers are the servers in the network that know everything about everything.

There has been others developing their own implementations of the SILC protocol as well. See our links page for links to those projects.

They are not actually. The SILC Client and SILC Server code is distributed in SILC Toolkit merely as example code for how to use the SILC Toolkit. The SILC Client and SILC Server distirbutions may include different code than what is found in the SILC Toolkit distribution. You should not use the client and server found in SILC Toolkit in production environment, but treat them merely as example applications.

Determined using TFT causal diagnostic procedures, the algorithms are precise treatment sequences that are known to have a curative effect when applied to specific problems.

The MAC (Message Authentication Code) for SILC packet in the secure binary packet protocol is always computed after the encryption from the ciphertext. This is so called Encrypt-Then-MAC order. Same order is used for example by the IPSEC (ESP) protocol to compute MAC. A packet sequence number is also used in the MAC computation. The MAC itself is appended at the end of the packet and is never encrypted.

The transport is protected with session keys negotiated during the SILC key exchange protocol. SILC protocol defines secure binary packet protocol, which provides encrypted and authenticated binary packets. All data in SILC are sent using this secure binary packet protocol and all packets are automatically encrypted. This is analogous of using TLS/SSL to protect the socket layer, except that SILC defines the binary packet protocol itself.
