Confusion Technology of Opaque Predicates
LI Xin-liang, LY Steel · Journal of Shenzhen Polytechnic · 2010
As one of program transformation techniques to protect mobile codes and software intellectual property,this paper introduces principles and research of confusion,then confusion based on fuzzy predicates is examined.A Java-based construction of fuzzy predicates is offered,which,for each branch point,can read the linked list structure,re-encode into the original output fuzzy predicate,and use knapsack encryption system to map the output,all of which increases the fuzzy predicate complexity,dynamic analysis of resistance against attackers and difficulty of de-complication.
