安全的实时传输协议SRTP的研究与实现

Research and Implementation of Secure Real-time Transport Protocol (SRTP)

安全的实时传输协议SRTP是实时传输协议RTP的一个扩展协议,该协议在RTP基础上加强了保密性,并定义了消息认证和完整性保护。本文分别介绍了SRTP/SRTCP包格式,加密环境和密钥产生方法等,并提出了用C/C++实现SRTP/SRTCP的方法。

Secure Real-time Transport Protocol (SRTP) is a profile of Real-time Transport Protocol (RTP). It enhances confidentiality and defines message authentication and integrity. This paper introduces SRTP/SRTCP format, Cryptographic Contexts and method of Key generation, respectively. Finally, a method to implement SRTP/SRTCP with C/C++ is proposed.
