会话发起协议中的无公钥认证机制

Towards Public Key Infrastructure less authentication in Session Initiation Protocol

Abdullah Al Hasib, Abdullah Azfar, Md. Sarwar Morshed

摘要:

会话发起协议(SIP)已经成为用于互联网协议语音(VoIP)信令的最主要协议。SIP协议的安全性是VoIP通信的一个重要考虑因素,因为流量是在不安全的IP网络上传输的。SIP中的认证过程从基于预共享秘密的解决方案到基于公钥基础设施(PKI)的解决方案。然而,由于基于PKI的解决方案的局限性,一些无PKI认证机制被提出。本文旨在介绍SIP中使用的或与SIP一起使用的不同认证方法的概述。我们首先强调SIP在VoIP通信的背景下的安全问题。然后我们说明了有关SIP认证机制的当前活动,包括研究界的最新发展和互联网工程任务组(IETF)内的标准化工作。最后,我们分析了这些方法的安全方面。

英文摘要:

The Session Initiation Protocol (SIP) has become the most predominant protocol for Voice over Internet Protocol (VoIP) signaling. Security of SIP is an important consideration for VoIP communication as the traffic is transmitted over the insecure IP network. And the authentication process in SIP ranges from pre-shared secret based solutions to Public Key Infrastructure (PKI) based solution. However, due to the limitations in PKI based solutions, some PKI less authentications mechanisms are proposed. This paper aims to present an overview of different authentication methods used in or together with SIP. We start by highlighting the security issues in SIP in the context of VoIP communication. Then we illustrate the current activities regarding the SIP authentication mechanisms including the recent developments in the research community and standardization efforts within the Internet Engineering Task Force (IETF). Finally we analyze the security aspects of these approaches.
