信息中心网络中公钥认证技术综述

A Survey of Public Key Authentication Technology in Information-Center Networking

在信息中心网络(ICN)架构中,同IP网络一样,为了实现不可信环境下可靠的信息交换和身份认证,需要依靠公钥技术提供数字签名和数据加密支撑。而随着ICN网络的进一步部署和应用,关于公钥认证的需求也更加多样化。本文分析了现有几种典型ICN架构中的公钥认证方式,分析其原理并指出其局限性和安全性问题,说明设计分布式认证方案的必要性。同时对现有的分布式认证方式进行介绍,给出分布式认证系统研究的进展和方向,并说明ICN网络中部署分布式认证系统需要研究和解决的问题,为后续的ICN分布式公钥认证技术研究提供参考。

In the information-centric network(ICN),like the IP network,in order to achieve reliable information exchange and identity authentication in an untrusted environment,we need to rely on public key technology to provide digital signature and data encryption support.With the further deployment and application of ICN network,the demand for public key authentication is also more diversified.This paper analyzes the public key authentication methods in several typical ICN architectures,interpreting their principles,pointing out their limitations and security problems,and explains the necessity of designing distributed authentication schemes.At the same time,the existing distributed authentication methods are introduced,the progress and direction of distributed authentication system research are given,and the problems that need to be studied and solved in deploying distributed authentication system in ICN network are explained,which provides a reference for the subsequent research of ICN distributed public key authentication technology.
