Abstract :
This paper presents a cryptographic key management solution to solve the access control problem in the role hierarchy. Based on one-way hash functions, we propose an efficient key assignment and derivation method. This solution uses a limited number of keys and hash functions. Also, the dynamic access control problems, such as adding/deleting roles, or modifying relationships between roles in the role hierarchy are considered and can be resolved.
