rc4 - the pseudo-random generation algorithm prga

A selection of articles related to rc4 - the pseudo-random generation algorithm prga:

RC4 falls short of the standards set by cryptographers for a secure cipher in several ways, and thus is not recommended for use in new applications. The keystream generated by RC4 is slightly biased in favour of certain sequences of bytes. The best attack based on this bias is due to Fluhrer and McGrew, which will distinguish the keystream from a random stream given a gigabyte of output

RC4 generates a pseudorandom stream of bits (a "keystream") which, for encryption, is combined with the plaintext using XOR as with any Vernam cipher; decryption is performed the same way. To generate the keystream, the cipher makes use of a secret internal state which consists of two parts: A permutation of all 256 possible bytes (denoted "S" below). Two 8-bit index-pointers (denoted "i" and "j")

RC4 falls short of the standards set by cryptographers for a secure cipher in several ways, and thus is not recommended for use in new applications. The keystream generated by RC4 is slightly biased in favour of certain sequences of bytes. The best attack based on this bias is due to Fluhrer and McGrew, which will distinguish the keystream from a random stream given a gigabyte of output. RC4 does not take a separate nonce alongside the key. As with any cipher, but particularly with Vernam ciphers, such a nonce is a requirement ...

* Encyclopedia II - RC4 - History
RC4 was designed by Ron Rivest of RSA Security in 1987; while it is officially termed "Rivest Cipher 4", the RC acronym is alternatively understood to stand for "Ron's Code" (see also RC2, RC5 and RC6). RC4 was initially a trade secret, but in September 1994 a description of it was anonymously posted to the Cypherpunks mailing list. It was soon posted on the sci.crypt newsgroup, and from there to many sites on the Internet. Because the algorithm is known, it is no longer a trade secret. The name "RC4" is trademarked, however. The curr ...

CAN STRONG AUTHENTICATION SORT OUT PHISHING AND FRAUD?

Authentication, especially two-factor authentication, is seen as an important step against on-line crime, especially for on-line banking and Internet shopping. But authentication alone is not enough to protect computer users against the efforts of organized crime to thieve their credentials, their data and even their identity.
