A Lightweight Mutual Authentication Based on Proxy Certificate Trust List

We propose Proxy Certificate Trust List (PCTL) to efficiently record delegation traces for grid computing. Our security solution based on PCTL provides functions as follows: (1) On-demand inquiries about real time delegation information of grid computing underway; (2) Lightweight mutual authentication that is beneficial for proxy nodes with limited computation power as wireless devices in mobile computing; (3) A kind of revocation mechanism for proxy certificates to improve the security and availability of grid computing
