Proxy signature based on pairing applied in mobile Agent

Proxy signature based on pairing has the advantage of IBE(identity based encryption). Mobile agent is an autonomy software that can be executed in various environments, such as low bandwidth or asynchrony. The mobile users can authorize mobile agent to search for the products or services in network automatically. Because of the property of mobile agent, people applied proxy signature in mobile agent for a long time, but lack of efficiency for the limitation of PKI( public key infrastructure). The purpose of this article is to solve this problem using the identity based proxy signature.
