| 摘 要： | 针对P2P环境中访问控制问题,将信任机制、信息的机密性和完整性及用户兴趣结合进行研究.引入了主体、客体的密级、完整性等级、兴趣值和信誉等级等概念.根据用户对资源感兴趣的程度并利用已有的访问控制策略思想,定义了新的基于兴趣分类、信任和安全等级的P2P访问控制策略.通过对其合理性的分析和研究得知,该策略是对已有的模型的访问控制策略的改进和扩展,适用于P2P网络环境的安全访问控制策略.

| Abstract: | In view of access control issues in the P2P environment,the trust mechanisms,information confidentiality and integrality,and the user interest are studied in this paper.In this regard,the classifications,and the integrality grade,the interest value,and the reputation grade,of the subject and of the object are introduced.A new access control P2P strategy based on interest classification,trust and security grade is defined in this paper,according to users' interest in the extent of the resource,and with the i... |
