Abstract

The invention provides a network telephone processing method and device and a terminal, and relates to the technical field of communication. The method is applied to a called terminal, and comprises the following steps: receiving a message for inviting a network call sent by a calling terminal, the message carrying first signature information and recognition information of the calling terminal, and the first signature information being signature information for signing a message header for inviting the network call; querying a blockchain certificate of the calling terminal according to the recognition information of the calling terminal; and verifying the first signature information according to a public key in a blockchain certificate of the calling terminal, and establishing a network telephone connection with the calling terminal when the verification is passed. According to the scheme provided by the invention, the problem of mutual trust among multiple CAs in the existing networktelephone is solved.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a network phone processing method, device and terminal. Background technique [0002] With the recent rise of Internet Protocol address IP access to the public switched telephone network PSTN, inexpensive IP-based client protocols (such as Session Initiation Protocol (SIP)) are replacing expensive traditional telephone services (such as Integrated Services Digital Network ISDN). Inexpensive Voice over IP (VoIP) phone service is now becoming the norm. The bearer of PSTN is also developing towards IP-based direction. [0003] Currently, if figure 1 As shown, the security mechanism in VoIP is to identify the identity of the initiator of the SIP request, and the identification process is as follows: [0004] (1) SIP client A sends a SIP invite message to the authentication server. [0005] (2) The authentication server signs the header of the SIP invitation message...
