We present our further observations on the structure of the AES algorithm relating to the cyclic properties of the functions used in this cipher. We note that the maximal period of...
Abstract. The motivation for this work is to support a natural separation of concerns during formal system development. In a developmentby-refinement context, we would like to be a...
In their work on tractable deduction systems, D. McAllester and later D. Basin and H. Ganzinger have identified a property of inference systems (the locality property) that ensures...
We describe the class of games with opacity condition, as an adequate model for security aspects of computing systems. We study their theoretical properties, relate them to reachab...
Currently, the requirements on MPEG encryption algorithms include: fast speed, format compliance, a wide range of security levels, easy implementation, etc. However, promising can...
