In general applications’, changing a secret key of a user provides maximum security for the system. Thus, a user in an organization needs to change his/her secret key from time to time to achieve maximum security. Changing the secret key of a user in an organization is more frequent than a user simply joining or leaving the organization. Dynamic properties such as changing the key of a user in a hierarchy affects the performance of an access control scheme more than other dynamic properties such as adding or deleting a security class to the hierarchy. As a result, we need to design an effective access control scheme to change keys of users in the hierarchy. However, most schemes proposed in the literature do not provide an efficient solution. In this paper, we propose a new key management mechanism for hierarchical access control that provides an effective solution. Moreover, our scheme efficiently supports other dynamic properties, such as adding or deleting a security class. Further, we proposed an efficient procedure for key generation and key derivation for access control. Through formal and informal security analysis, we prove our scheme tolerates various known attacks in access control. We show that our scheme has better performance compared to other related schemes. As a result, higher security along with efficient access control properties makes our scheme more suitable for practical applications.
