【摘要】 P2P网络的安全需求中,信任关系的建立是重点也是难点。传统的信任评估模型,采用适当的信任评估手段,能够在一定程度上削弱单纯欺骗、不作为、诽谤和联合作弊的安全威胁,但却不能有效地抵御Pseudospoofing和Pseudostheft攻击。在本文中,我们将可信计算组织推出的可信计算技术引入P2P网络,提出了一种有效的P2P网络实体数字身份的创建和管理策略。新的信任模型在信任评估过程中贯穿着平台认证,很好地解决了P2P网络的安全问题。更多还原

【Abstract】 Building trust relationships between entities is an important and difficult part in the security needs of P2P networks.By using appropriate assessment tools,traditional trust models can weaken some security threats such as simple deception,an omission,defamation and joint cheating to a certain extent,however they are unable to resist the attacks of Pseudospoofing and Pseudostheft effectively.In this paper,the trusted computing method initiated by Trusted Computing Group(TCG) is introduced into P2P networks,and we propose an efficient scheme on foundation and management of stable and verifiable digital identities of entities.The new designed trust model,using platform attestation technology through the whole process of trust evaluation,perfectly solved security problems of P2P networks.更多还原
