Slicing Aided Design of Obfuscating Transforms

Stephen Drape, Anirban Majumdar, Clark Thomborson
2007 6th IEEE/ACIS International Conference on Computer and Information Science (ICIS 2007)  
In this paper we present a novel approach to creating obfuscating transforms which are designed to survive slicing attacks.  ...  Thus slicing could be used as a way of attacking obfuscated programs. Can we design obfuscations which are more resilient to slicing attacks?  ...  CONCLUSIONS AND FUTURE WORK In this paper we have proposed a novel way to design obfuscating transforms by considering the maxim: "Attack is the best form of defence".  ...
