基于PKI的安全的点对点信息共享

摘要：信息自由流通的功能，使得了点对点的信息共享应用受欢迎。然而，这个非常功能阻碍接受这些应用程序的企业和科研社区。在这些社区提供保密性和完整性的通信并强制访问控制，以共享资源是很重要的。我们目前收集了安全机制，可用于满足这些安全要求。我们的解决方案是基于已建立和已被证明的安全技术上的，在可能的情况下我们利用现有的技术。作为一个概念证明，我们已经制定了一个信息共享系统，称为scishare ，它集成了一些安全机制，以提供一个安全的环境信息共享。这一系统将让更广泛的用户群体能够受益于点对点的信息共享。

Abstract: Free flow of information is the feature that has made peer-to-peer information sharing applications popular. However, this very feature holds back the acceptance of these applications by the corporate and scientific communities. In these communities it is important to provide confidentiality and integrity of communication and to enforce access control to shared resources. We present a collection of security mechanisms that can be used to satisfy these security requirements. Our solutions are based on established and proven security techniques and we utilize existing technologies when possible. As a proof of concept, we have developed an information sharing system, called scishare, which integrates a number of these security mechanisms to provide a secure environment for information sharing. This system will allow a broader set of user communities to benefit from peer-to-peer information sharing.
