英文摘要	A formal definition and analysis on the hierarchical key management is presented for permission management and access control problem in the role hierarchy. Based on one-way hash function, a practical hierarchical key management scheme is proposed. This scheme allows the role to select its master key by itself, and constructs the hierarchical permission relationship with secure hash function and public parameters. The process of key generation and derivation is simple and effective in this proposed scheme, which satisfies the security requirement of the hierarchical permission management. Compared with other present schemes, the new scheme optimizes the efficiency of key derivation and storage overhead. The dynamic access control of hierarchical role can be adapted in this new scheme.; EI; 0; 4; 527-536; 44
