WiPSec: security service architecture for wireless pervasive computations

The uncompleted structure of secure protocols blocks wireless/mobile users from conducting secure E-transactions. We first propose practical system architectures, called WiPSec, for secure wireless pervasive computing. We then describe how security and privacy are enforced using four separate protocols, one for each of the following: device and proxy communication; proxy and proxy communication; proxy and server communication; server and server communication. A concrete example is presented to illustrate how WiPSec solves the computationally intensive problem in a wireless environment. Finally, we extend the architecture and protocols to a wireless peer-to-peer (P2P) network.
