摘要
隐私资源的保护是多域间互操作以及P2P等技术实施的关键性安全问题。已有的解决方案虽然解决部分问题,但仍然存在着隐私信息泄露的可能,并没有很好地保证隐私资源的机密性,或者会泄露其他的隐私信息。分析了隐私资源保护的安全目标,提出了一种基于标识的保护方案。该方案不仅满足了安全目标,而且一次通信就能完成隐私资源的交换。最后,该方案被证明具有IND-CCA2语义安全性。
Privacy preservation is a vital problem to interoperation among multi-domains. The existing schemes can not resolve those troubles in privacy preservation very well, such as confidentiality, or leaking additional privacy information. The target of security about privacy preservation was analyzed, and then an identify based privacy preservation scheme was proposed. The scheme not only satisfies the security target, but also need only once communication. Finally, the scheme was proved to be of IND-CCA2 semantic security.
