Anti-collision interruptible recovery voice secret transmission method, device and system

Abstract

The invention relates to the technical field of communication security, and discloses an anti-collision interruptible recovery voice secret transmission method, device and system, and the method comprises the steps: carrying out grading of a user terminal, employing an identity secret key to read an identifier, obtaining a transmission secret key through the identifier, carrying out transmission of a session secret key through the transmission secret key, and establishing an encrypted session through the session key. The device comprises a user terminal, a server and a background database, thesystem comprises one or more processors, a storage device and an anti-collision interruptible recovery voice secret transmission device. Conflict processing of multiple voice communication requests can be achieved, voice communication can be conveniently and reliably kept secret, and meanwhile, when the session is accidentally interrupted, effective unification of confidentiality recovery, data two-party identification and data confidential transmission can be realized, so that the confidential data is prevented from being maliciously eavesdropped or counterfeited, and the method has a relatively good practical value.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to a method, device and system for anti-collision and interruptible and recoverable speech confidential transmission. Background technique [0002] With the continuous development of technology, mobile or wireless communication has been widely used by people as a convenient way of communication. With the increasing popularity of wireless or mobile communication technology, the issue of communication security has become increasingly prominent and has become an important issue that people pay attention to. [0003] On the one hand, in the prior art, when multiple confidential calls are required, key coverage or session conflicts may occur, resulting in the inability to decrypt, leading to the problem that confidential communication cannot be carried out; [0004] On the other hand, in existing communication, in order to realize secure communication, confidential convers...
