Abstract

A session information interaction method, apparatus and system. The method includes: negotiating for encryption with an opposite end, determining the key and the encryption algorithm (101); sending or receiving session information, the message body of the session information is encrypted using the key and the encryption algorithm (102). In the embodiments of this invention, the client negotiates for encryption with the interactional opposite end by receiving and sending session request and session response information including the content of the key and the encryption algorithm. It does not need to involve third party flow, and the complication of the encryption flow is reduced; moreover, only the message body of the session information is encrypted, so that when the session information is transmitted in the network, the intermediate nodes do not need to encrypt and decrypt the session information, and the transmission time is saved.

Description

technical field [0001] The present invention relates to the field of network technology, and more specifically, to a session information interaction method, device and system. Background technique [0002] With the continuous development of NGN (Next Generation Network, next-generation network) technology, for NGN to realize VoIP (Voice over Internet Protocol, voice transmission protocol on the Internet) and multimedia communication on the IP network, SIP (Session Initiation Protocol, Session Initiation Protocol) has unique advantages in fully meeting the requirements of NGN characteristics, and has gradually become an important solution for VoIP in the next generation network. [0003] In order to ensure the security of SIP session information, at present, TLS (Transport Layer Security, transport layer security) and S / MIME (Secure Multipurpose Internet Mail Extensions, secure multipurpose Internet mail extensions) are commonly used to process SIP messages, thereby protectin...
