Summary: | 碩士 === 亞洲大學 === 資訊工程學系 === 102 === The role-based hierarchical key assignment problem is to assign sensitive keys to security role-based classes in a partially ordered hierarchy so that legal data accesses among classes can be enforced according to the role’s privileges. In role-based RSA key hierarchy management scheme, a user is assigned the role which could derive the RSA key corresponding to the assigned role-based class and its successors’ classes in order to access specific contents of resources. A novel scheme based on keys is proposed to manage the cryptographic key for access control in role-based hierarchical system. Both RSA algorithm and Akl approach are applied to the scheme. The performance comparison is presented in this paper. Besides, our scheme provides a very easy implement and simple key storage manner to increase the availability of user access.
