Towards Better Encryption Based Software Self-Checking Tamper Resistance

Upon with the encryption technology based on software self-checking tamperresistance and taken self- checking and software behavior tracing as the key technology,the branch-based code obfuscation is introduced to protect the integrity and security of client software.This paper offers the modified tamper resistant system and its main modules, and analyzes the security of the scheme,and provides results of the experiment test.
