Terminal mutual-trust building method without agent quantum bit commitment agreement and simulation device

Abstract

The invention discloses a terminal mutual-trust building method without an agent quantum bit commitment agreement and a simulation device. The method comprises the steps of 1, obtaining target bits bymutually communicated terminals; 2, generating a commitment message and sending the commitment message to a verification terminal by a commitment terminal; and 3, verifying whether the commitment terminal is a lawful commitment party by the verification terminal, if so, judging that communication between the verification terminal and the commitment terminal is trusted, otherwise, ending current communication with the commitment terminal by the verification terminal, wherein the verification terminal compares the decrypted commitment message with the target bits to obtain a verification control bit or a conclusion that the commitment terminal is not the lawful commitment party, the verification terminal compares whether the verification control bit is same as the commitment bit or not, ifso, judging that the commitment terminal is the lawful commitment party, otherwise, judging that the commitment party is not a lawful commitment party. Trust between communication terminals is built without a third-party public platform, and the complexity of a communication protocol is reduced while communication safety is improved.

Description

technical field [0001] The invention belongs to the technical field of quantum communication, and in particular relates to a terminal mutual trust construction method and a simulation device of an agentless qubit commitment protocol. Background technique [0002] With the rapid development of e-commerce, especially Internet finance, more and more communicators who lack mutual trust, such as Internet terminals, need to cooperate. Therefore, ensuring the establishment of trust between terminals that do not trust each other has become a guarantee for the future Internet. The foundation of healthy economic development, and the realization of a secure "bit promise" is the foundational topic that must be resolved in this type of research. In order to realize the security "bit promise", scientists from various countries have made unremitting efforts in the past few decades. Among them, there are two solutions in classical cryptography, which are using third-party public platforms ...
