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 is performed bit by bit. sharon renae photography

WebWe saw a general attack on block cyphers which we called exhaustive search. And that attack forced the key size for a block cypher to be 128 bits or more. Similarly on collision resistance there is a general attack called the birthday attack which forces the output of collision resistant hash functions to be more than a certain bound.
