CipherSaber Guide, Meaning , Facts, Information and Description
CipherSaber is a symmetric encryption system based on RC4 that is strong, yet simple enough that novice programmers can implement it from scratch. In CipherSaber each message begins with a random ten byte initialization vector (IV). This IV is appended to the CipherSaber key to form the input to the RC4 key setup algorithm. The IV is needed because RC4 is a stream cipher.Related key attacks on RC4 have rendered the original CipherSaber system vulnerable if a large number (>1000) messages are sent with the same CipherSaber key. CipherSaber-2 overcomes this difficulty by repeating the RC4 key setup loop multiple times (20 is recommended).
