Abstract. This paper presents xmx, a new symmetric block cipher optimized for public-key libraries and microcontrollers with arithmetic coprocessors. xmx has no S-boxes and uses on...
Traceability is a property of a communications protocol that ensures that the origin and/or destination of messages can be identified. The aims of this paper are twofold. Firstly t...
In [1] a construction of a block cipher from a single pseudorandom permutation is proposed. In a complexity theoretical setting they prove that this scheme is secure against a pol...
