Randomness measures related to subset occurrence,roblems in applying these tests as the size of the subsets increases. We propose a novel method based on the classical occupancy problem to deal with larger subsets in testing for randomness in a keystream in the case of a stream cipher and for independence between subsets of input and output blocks in the case of a block cipher.

Multiple encryption with minimum key,underlying cipher. We propose a new variant of two-key triple encryption which is not vulnerable to the meet in the middle attack and which uses a minimum amount of key. We can prove a connection between the security of our system and the security of the underlying block cipher.
