摘要: In 2004, Yang and Li addressed an access control scheme based on one-way hash function that uses limited number of keys and some public hash functions to solve the dynamic access control problem. Our research finds that in their scheme users can overstep his authority to access unauthorized information. We further propose a robust dynamic access control scheme to eliminate such an attack.
