A method, system and device for securing multi-party communication

Abstract

The utility model discloses a method that can realize multiparty communication security. The method is an improvement to the transport layer security protocol or the datagram transport layer security protocol, which aims to solve the disadvantages of bad portability and low deployment of the present multicast security protocol family and avoid the disadvantages of high input and big risk brought by developing a new technical proposal. The method comprises that: step a: identity authentication is performed to a group control key management server and a member equipment by running the transport layer security protocol or the datagram transport layer security protocol, and an initial session is created by negotiation; step b: the group control key management server and the member equipment distribute a group session and a key updating session to other group member equipments by running a group key management sub-protocol; step c: when the group control key management server detected a key updating event, the group control key management server and the member equipment update the key by running the group key management sub-protocol. The utility model also discloses a multiparty communication security system and equipment.

Description

technical field [0001] The present invention relates to a network communication, in particular to a network communication security technology, more precisely, the present invention relates to a multi-party communication security technology. Background technique [0002] With the rapid development of information technology, people's requirements for communication are no longer limited to point-to-point communication, but multi-party communication. Multi-party communication is also called group communication, which refers to a communication scenario involving more than two members. The scenario of only two parties is a special case of multi-party communication. Common multi-party communication scenarios include remote multi-party conferences, IP (Internet Protocol, Internet Protocol) telephones, IP televisions, online online games, grid computing, and the like. [0003] Security requirements for multiparty communications include: authorization and authentication, confidential...

AI Technical Summary

Problems solved by technology

[0012] The purpose of the present invention is to provide a method and system for realizing multi-party communication security by extending the TLS or DTLS protocol, to inherit the advantages of good portability and high deployability of the original TLS and DTLS, and to solve the problem of the existing MSEC protocol family. The disadvantages of poor portability and low deployability of the solution, and avoid the disadvantages of high investment and high risk of developing new solutions from scratch
