Improved Impossible Differential Cryptanalysis of Rijndael and Crypton,acks to 6-round. Although we use the same 4-round impossible differential as in five round attacks, we put this impossible differential in the middle of 6-round. That is, we will consider one round before the impossible differential and one more round after. The complexity of the proposed attack is

Improvement of Probabilistic Public Key Cryptosystems Using Discrete Logarithm,based on the discrete logarithmic function and the messages are calculated from the modular product of two those functions, one of which has a fixed value depending on a given public key. The improvements are achieved by a good choice for the public key so that it is possible to get efficient algori
