Secure Transmission of Mobile Agent in Dynamic Distributed Environments

Huang et al. has recently proposed an efficient key management and access control scheme for mobile agent environments based on Elliptic Curve Cryptosystem (ECC). Although their scheme provides superior efficiency in comparison with the previous works, however some active attacks threaten its security. In this paper a new dynamic key management scheme based on ECC is proposed that is secure and also is efficient in computation cost. Analyzing the security criteria and performance confirms suitability of the proposed scheme for mobile agent environments.
