SIP security authentication method and system based on on-loop error learning problem

Abstract

The invention discloses an SIP security authentication method and system based on an on-loop error learning problem, and the method comprises the steps: a user client U encrypts a password PW to obtain encrypted data PWE, and transmits a user name ID, the encrypted data PWE and a verification key to a server S; the server S receives the user name ID and the encrypted data PWE sent by the user client U, and encrypts the received data to obtain encrypted data VPW; the U sends a verification request to the S; the S uses the verification key to process the encrypted data VPW to obtain a first verification message; and the server sends the first verification message to the U; after the U receives the first verification message, the user client verifies the first verification message, and if theverification is passed, the client returns a second verification message to the server S; and the server S verifies the second verification message, and if the second verification message passes theverification, the client U and the server S use a common session key to encrypt the communication information.

Description

technical field [0001] The present application relates to the technical field of secure communication, in particular to a SIP security authentication method and system based on a learning problem with errors on a ring. Background technique [0002] The statements in this section merely mention the background art related to this application, and do not necessarily constitute the prior art. [0003] Authentication protocol is one of the important means to ensure the secure exchange of information between communicating entities in an untrusted environment. Session Initiation Protocol (SIP) has become the most widely accepted signaling protocol for Internet telephony due to its simplicity, openness, publicity, standardization and personalization. It is a signaling protocol for multimedia conferences and telephones developed by the Internet Engineering Project Group, and is used to create, modify and terminate two-party or multi-party multimedia session processes. When a remote...
