A communication method and system based on quantum ukey

Abstract

The invention discloses a communication method and system based on the quantum Ukey, aiming to solve the potential safety hazards that the algorithm is not safe, the user password strength is not highenough, the user password plaintext input, secret key distribution and management are difficult, and the secret key cannot be automatically updated in the aspects of current identity authentication and security access cloud service application. The communication method based on the quantum Ukey comprises the following steps that when an access application service instruction is acquired, a user terminal determines a first quantum key by the quantum Ukey established the connection relation, and sending the corresponding authentication message to an authentication management platform for identity authentication; the authentication management platform obtains a second quantum key from the KMS according to the authentication message, and decrypting the encrypted information in the authentication message, if the decrypted information is consistent with the plaintext information in the authentication message, the identity authentication is determined to pass, and the passing information isreturned to the user terminal, so that the user terminal accesses the application server through the first quantum key.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication method and system based on quantum UKey. Background technique [0002] Quantum communication technology is a new technology developed in recent decades. It is the product of the combination of quantum theory and information theory. It is the only secure communication technology whose security has been strictly proved, and can realize the safe distribution of keys. In the field of application, quantum gateways are generally used to generate symmetric quantum keys at two clients through quantum channels and use them to encrypt communication data at both ends to ensure the security of data communication. However, due to the large size of existing quantum gateway products, it is not suitable for certain occasions, such as mobile office. Quantum cryptography differs from traditional cryptographic systems in that it relies on physics rather than mathematics as a...
