Substitution Encryption Algorithm Study for Embedded Mobile Code Protection
Jingde Hu, Shi Gang · 2009
Protecting against software attacks is becoming a major concern in embedded systems since many of them have more and more functionality added. In this paper, an obfuscation-based approach for providing security of programming a remote embedded Java device is proposed. The basic idea of the proposed approach is that the programming system and the authorized embedded node exchange a Java bytecode substitution table using standard encryption techniques.
