Here p c a and b are each numbers in the range 0 to 25 where p represents the plaintext letter c the ciphertext and a and b are constants. For the plaintext and ciphertext 0 corresponds to "a" 1 corresponds to "b" and so on.

Examining the bit patterns of P1 + P2 can easily result in recovering one of the plaintexts. The latter can then be XORed with its ciphertext to yield the keystream. By transforming one bit at a time the XOR operation lends itself well to a class of encryption algorithms known as stream ciphers.

WebThere is no universally accepted definition of the expression "stream cipher"; but the one I most often encounter is the following: a stream cipheris a symmetric encryption algorithm which accepts as inputs arbitrary sequences of bits (or bytes) such that: the length of the output is equal to the length of the input (no padding);
