In many practical applications, the task is to optimize a non-linear objective function over the vertices of a well-studied polytope as, e.g., the matching polytope or the travelli...
Abstract. Serpent is one of the 5 AES finalists. The best attack published so far analyzes up to 9 rounds. In this paper we present attacks on 7-round, 8-round, and 10-round varia...
With the expiration of the Data Encryption Standard (DES) in 1998, the Advanced Encryption Standard (AES) development process is well underway. It is hoped that the result of the ...
The results of fast implementations of all five AES final candidates using Virtex Xilinx Field Programmable Gate Arrays are presented and analyzed. Performance of several alternati...
