摘要

摘要: 由于命名数据网络(NDN)具有网内缓存特点，任意用户可直接从中间路由节点获取数据，同时，内容提供商也无法得知用户的访问信息。针对这些问题，该文结合基于身份的组合公钥和Schnorr签名方法，提出了“三次握手”匿名安全认证协议，同时，采用改进的秘密共享方法来高效分发内容密钥，实现了一种可追溯且轻量级的细粒度访问控制机制(TLAC)，最后，通过实验验证了TLAC机制的高效性。

Abstract: Due to the feature of in-network caching in Named Data Networking (NDN), any consumer might fetch the cached contents from NDN routers, but the content producers have no idea about details of certain contents being accessed. Considering these problems, a fine-grained Traceable and Lightweight Access Control (TLAC) scheme is presented. In the TLAC scheme, an anonymous and secure " three-way handshake” authentication protocol is presented by collaboratively leveraging the combined public key and the Schnorr signature, and an improved secret sharing method is used to distribute the key efficiently. Finally, the experimental results prove the efficiency of TLAC scheme.
