An Attack and Repair of Secure Web Transaction Protocol for Anonymous Mobile Agents

The security problems that impact mobile agents include authentication and privacy. A challenging task is to implement secure mobile agents that provide anonymity for the mobile agent. Wang, Zhang, and Wang constructed a scheme that provides secure web transactions with anonymous mobile agents over the internet. Our paper will discuss the Wang, Zhang and Wang protocol(WZW) thoroughly, our work demonstrates the weaknesses of the WZW protocol, showing that it is not as secure as it is claimed to be. In this paper, we will construct attacks on the WZW protocol, provide several repairs and construct a secure scheme for conducting E-commerce using anonymous mobile agents.
