Weak Keys of CRYPTON

The block cipher CRYPTON is a candidate proposal for the AES standard. In this report we describe a class of 232 weak keys. This is mainly a consequence of the use of linear operations in the key schedule. These weak keys especially have consequences for the use of CRYPTON in certain hash function constructions.
