WebReused key attack [ edit] Stream ciphers are vulnerable to attack if the same key is used twice (depth of two) or more. Say we send messages A and B of the same length, both encrypted using same key, K. The stream cipher produces a string of bits C (K) the same length as the messages. The encrypted versions of the messages then are: where xor ... WebAs computing advanced, this proved ineffective protection against certain attacks. The algorithm was retired in 2005. In 1998, Triple Data Encryption Algorithm, commonly referred to as Triple DES, TDEA and, informally, 3DES, was introduced. It applies the DES cipher algorithm three times to each data block for more effective key length.
