WebSep 30, 2016 · Let (E,D) be a (one-time) semantically secure cipher with key space K={0,1} ℓ. A bank wishes to split a decryption key k∈{0,1} ℓ into two pieces p1 and p2 so that both are needed for decryption. The piece p1 can be given to one executive and p2 to another so that both must contribute their pieces for decryption to proceed. WebAn affine cipher is a type of simple sub where each letter is encrypted acc to the rule c = (a*p+b)mod 26. 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.

WebA particular cipher is implemented by combining the ASCII representation of plaintext characters with pseudorandom bytes (eight-bit binary strings of 1s and 0s) using the XOR function. In the process of encrypting a message, a character in the plaintext, a capital E, is XORed with the pseudorandom byte 10010101.
