,Crypto in Europe — markets, law and policy,owing proportion of the world economy based on transactions protected by cryptography, this is likely to be a much more serious problem for law enforcement than occasional use of cryptography by criminals.

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.
