Behavioral detection differs from appearance detection in that it identifies the actions performed by the malware rather than syntactic markers. Identifying these malicious actions and interpreting their final purpose is a complex reasoning process. This paper draws up a survey of the different reasoning techniques deployed among the behavioral detectors.(More)
Behavioural analysis for detection of mal-ware has recently emerged as a new promising set of antiviral techniques: function-based detection is now considered along with sequence-based detection. Most of the antivirus publishers now claim to use behav-ioral analysis as a marketing argument. But the real impact of these " new " techniques seems to be(More)
This paper presents a new stream cipher family whose output bits are produced by blocks. We particularly focus on the member of this family producing 128-bit blocks with a 256-bit key. The design is based on a new technique called crossing over which allows to vectorize stream ciphering by using nonlinear shift registers. These algorithms offer a very high(More)
