Design of Role-Based Access Control Scheme in USB Cryptographic Card

Role-Based Access Control (RBAC) is a kind of access control mechanism which is convenient and secure. To protect the resources of USB cryptographic card, a RBAC method is purposed and implemented in this paper, which meets the need of access control, least privilege, small computation and managed easily. Analyses the need of the USB cryptographic card, compares several main access control models, introduces the characteristic and application advantages of RBAC, finally demonstrates in detail how to apply RBAC in USB cryptographic card.
