摘要： 针对多安全政策支持结构，特别是通用访问控制框架在加入多个安全政策后效率明显下降的问题，该文借用人工免疫系统的一些原理，通过引入免疫识别、免疫学习和免疫记忆等机制，提出一个基于免疫功能的通用访问控制框架。仿真实验表明，该框架有效提高了系统访问控制决策的效率，具备一定的自适应能力和多样性。

Abstract: With regard to the problem that the efficiency of the classical multi-policies supporting mechanism, namely the Generalized Framework for Access Control(GFAC), markedly declines after enforcing several policy modules, a novel access control framework based on immunity is constructed with employing multiple principles and mechanisms of the artificial immune system, such as the immune recognition, the immune learning and the immune memory. Simulation result shows that IGFAC is able to improve the performance of the original GFAC, and it has some self-adaptive capabilities and diversity behaviors.

Key words: access control, information security, artificial immune system, self-adaptive
