This paper is primarily concerned with the CBC block cipher mode. The impact on the usability of this mode of recently proposed padding oracle attacks, together with other related ...
In this paper we give a specification of a new block cipher that can be called the Courtois Toy Cipher (CTC). It is quite simple, and yet very much like any other known block ciph...
The software-efficient stream cipher HC-256 was proposed by Wu at FSE 2004. Due to its impressive performance, the cipher was also a well-received entrant to the ECRYPT eSTREAM com...
In this paper we consider an attack on the SIGABA cipher under the assumption that the largest practical keyspace is used. The attack highlights various strengths and weaknesses o...
Building on the work of Kocher[Koc96], Jaffe, and Yun [KJY98], we discuss the notion of side-channel cryptanalysis: cryptanalysis using implementation data. We discuss the notion o...
