Yong Sheng · Journal of Information Engineering University · 2004
Secure 0S need adequate protection mechanisms to flexible support wide range of security policies.The policy flexibilities include controlling migrated access permissions,performing fine grain access control and revoking permitted access permission.But some 0S have shortcomings in these characteristics.The author introduces a flexible security architecture to overcome the limitation of traditional mechanisms.The architecture implemented the mechanisms to control migrated access permissions,to use access decision cache,fine grain control and migrated permission revocation mechanism.
