Problems solved by technology

At present, quantum key distribution on quantum channels is relatively close to practicality, but quantum channels cannot be used as natural confidential channels to directly carry out secure communication of plaintext information.
[0005] At present, the research in the field of anti-quantum computing cryptography mainly focuses on public key encryption and digital signature, while the research on key exchange protocols with the potential of anti-quantum computing is less

Abstract

The invention relates to the technical field of information security, in particular to a shared secret key establishment method under quantum computing environment. The shared secret key establishment method comprises two steps of establishing a system and establishing a shared secret key between A and B which are communicated. The shared secret key establishment method is provided by adopting of a multinomial homomorphism problem and has the advantages that realizing efficiency is high, a cryptographic algorithm coprocessor is not needed, safety is high, and the attack from a quantum computer is resisted. In the safety fields such as intelligent cards and wireless sensor networks, the shared secret key establishment method has the advantages over traditional secret key exchange protocols such as a Diffie-Hellman secret key exchange protocol. The shared secret key establishment method can be widely applied to information security system fields such as network security and electronic commerce.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for establishing a shared key in a quantum computing environment. Background technique [0002] Aiming at the complex problem of key management in symmetric cryptosystems, Diffie and Hellman pioneered the concept of "public key cryptosystem" in 1976, pointing out that secret information can be transmitted on open channels. Compared with symmetric cryptography, encryption and decryption operations in public key cryptography systems are generally more complex and less efficient, so they are not suitable for directly encrypting large amounts of data. The usual practice is: use public key cryptography (key establishment protocol) to establish a shared session key; then, use the session key as the key of the symmetric cipher to encrypt a large amount of plaintext information. [0003] Generally speaking, key establishment protocols can be divided into: key distr...
