We present a chosen-ciphertext attack against both NICE cryptosystems. These two cryptosystems are based on computations in the class group of non-maximal imaginary orders. More pr...

We improve the best attack on Rijndael reduced to 6 rounds from complexity 272 to 244 . We also present the first known attacks on 7- and 8-round Rijndael. The attacks on 8-round R...
