Constructing Opaque Predicates for Java Programs

This paper proposes a new method to construct a family of opaque predicates for Java programs by combining indeterminate equation and cryptography. In our construction, cryptography is first exploited for manufacturing opaque predicates. Our opaque predicates are more resilient, stealthier and cheaper. Our opaque predicates are dynamic and secure against all usual types of static attacks and dynamic attacks, also secure against crypto analysis
