An authentication method for network signaling between quantum secure network devices

Abstract

The invention discloses an authentication method for network signaling between quantum safety network equipment. The authentication method includes the following steps: creating synchronous signaling key stores used for signaling authentication for both sides between the communicated network equipment, wherein the synchronous signaling key stores are divided into an encrypting signaling key store and a decrypting signaling key store, and setting a read indicator and a write indicator for each signaling key store; a sending end calculating related hash operation message authentication codes H of keys based on key data and a read indicator offset address of the encrypting signaling key store of the sending end, and sending a corresponding signaling data packet to a receiving end; the receiving end receiving the signaling data packet, acquiring a read indicator offset address in the signaling data packet, and judging whether the key data of the read indicator offset address of the decrypting signaling key store of the receiving end is already used or not; and if the key data is not used, calculating H and verifying the content of the signaling data packet. The authentication method for the network signaling between the quantum safety network equipment has the advantages that the authentication is fast, and the method has a certain preventive effect on distributed denial of service (DDoS) attacks, can achieve true one-time-one-key encrypting authentication and is absolutely safe theoretically.

Description

technical field [0001] The invention relates to a quantum security communication network, in particular to an authentication method for communication signaling between network communication terminal devices in the quantum security communication network. Background technique [0002] Security is an important evaluation index in communication network, and cryptography provides a strong guarantee for secure communication. Traditional cryptography is based on the computational complexity of mathematical algorithms and cannot guarantee the absolute security of keys. Quantum cryptography uses the basic principles of quantum mechanics to ensure the absolute security of passwords: any measurement of a quantum system will interfere with the system, and if a third party tries to eavesdrop on the password, it must be measured in a certain way, and its measurement will bring security. The perceived abnormality will be known to the communicating parties, which is one of the most importa...

Problems solved by technology

The one-time secret key mechanism of the quantum security network makes the key impossible to be cracked, and the encrypted data cannot be effectively constructed by itself. The only thing that the attacker can effectively use is the intercepted encrypted data
