One hindrance to the widespread adoption of mobile agent technology is the lack of security. Security will be the issue that has to be addressed carefully if a mobile agent is to be used in the field of electronic commerce. SAFER or Secure Agent Fabrication, Evolution, and Roaming is a mobile agent framework that is specially designed for the purpose of electronic commerce (Zhu, Guan, Yang, & Ko, 2000; Guan & Hua, 2003; Guan, Zhu, & Maung, 2004). Security has been a prime concern from the first day of our research (Guan & Yang, 1999, 2002; Yang & Guan, 2000). By building strong and efficient security mechanisms, SAFER aims to provide a trustworthy framework for mobile agents, increasing trust factors to end users by providing the ability to trust, predictable performance, and a communication channel (Patrick, 2002).
