Attack model library establishment method in quantum cryptographic protocol

Abstract

The invention discloses an attack model library establishment method in a quantum cryptographic protocol. An attack model library comprises an interception retransmission attack model, a random replacement attack model, a general attack model, a Trojan Horse attack model and an invisible photon attack model. The interception retransmission attack model is as follows: a transmitter transmits a sequence Ai to an information channel; an eavesdropper completely intercepts sequence and randomly selects a measurement basis to measure each photon and record a result Ei; the eavesdropper obtains a new sequence Ei' while all photons are measured and transmits the sequence to a receiver, and the receiver obtains a result Bi. The model library established by the method comprises the interception retransmission attack model, the random replacement attack model, the general attack model, the Trojan Horse attack model and the invisible photon attack model. By accurately describing the process of the five attack manners, the method is suitable for the communication protocol with similar property and could effectively detect the wiretap to ensure the communication safety.

Description

technical field [0001] The invention relates to a method for establishing an attack model library in a quantum cryptography protocol. Background technique [0002] The development of the network is becoming more and more complicated, and ensuring the security of the information network has become the core content of the national informatization strategy. In a specific network environment, the threat of stealing secrets through special means is becoming increasingly serious. , eavesdroppers can steal information from the channel, which poses a threat to information security. The main purpose of eavesdropping is to obtain secret information transmitted between legitimate users, and the most important thing about quantum cryptography protocol is its security. There are many ways to attack the quantum communication process. A model checking method is proposed to model eavesdropping in quantum cryptography protocols. When the security properties of a protocol need to be verifie...
