A New Authentication Scheme for Protecting Mobile Agent Platforms Using Pairing-Based Cryptosystems

Abstract

This paper presents an authentication scheme for protecting mobile agent platforms against unauthorized mobile agents using the proposed self-certified pairing-based public key cryptosystem. The proposed cryptosystem is constructed using the pairing-based cryptosystems, and is developed by integrating the identity- based public key cryptosystems with the self-certified public key cryptosystems to provide higher security strength. In addition, we employ the integrated cryptosystems to design an authentication scheme so that a mobile agent can register once to a system authority for many services in the mobile agent based networks. As far as agent platform security is concerned, we apply the idea of proxy signature to construct the proposed authentication scheme to protect mobile agent platforms. In summary, this platform protection scheme is based on the proposed cryptosystem to accomplish the requirements of authentication and authorization of mobile agents in a new way by proxy signature.
