In this paper we analyze the block cipher SAFER K. First, we show a weakness in the key schedule, that has the effect that for almost every key there exists on the average three an...

We prove that Tandem-DM, one of the two “classical” schemes for turning a blockcipher of 2n-bit key into a double block length hash function, has birthday-type collision resist...
