WebThe input plain text will be divided into blocks and each block will be encrypted with the key provided and hence identical plain text blocks are encrypted into identical cipher text blocks. CBC(Cipher Block Chaining) mode is highly recommended, and it is an advanced form of block cipher encryption. WebThe probability of failure for this algorithm is the probability that none of the 100 ciphertexts can be inverted using algorithm A, which is (0.99)^100, or approximately 0.366. Thus, the algorithm has a success probability of at least 1 - 0.366 = 0.634.
