Abstract

The invention provides a mail transmission system and a mail transmission method based on a quantum security key. The mail transmission system comprises a mail box system; a quantum random number generator; a quantum exchange cipher machine in which a secret key is pre-stored; a quantum key charging machine which is connected with the output end of the quantum exchange cipher machine; a quantum password management service system which is used for providing a mail encryption key and an identity authentication function; quantum security chips which are used for storing quantum security keys, the keys stored in each quantum security chip and the keys pre-stored in the quantum exchange cipher machine are symmetric keys, and symmetric entity authentication is carried out on the security keys in the quantum security chips through a network and a quantum cipher management service system; and a mail transceiver which is internally or externally connected with a quantum security chip. By adopting the technical scheme, the threat of an environment with increasingly severe network attacks to a mailbox transceiving environment is solved, the security threat brought by a quantum computer and a quantum algorithm in the future is prevented, and the scheme is easy to implement.

Description

technical field [0001] The application belongs to the field of security application products, and in particular relates to a quantum key-based system and method for secure email authentication and email encryption. Background technique [0002] At present, the increasingly severe environment of network attacks poses a threat to the mailbox sending and receiving environment, including: the identity authentication of the sending and receiving entity of the mail, the problem of the content of the mail being stolen during the process of mail transmission and storage, and the possible existence of the sender and receiver during the mail transmission process. Tampering and email message tampering issues. [0003] Application date: 2019.09.24, application number: CN201910904251.5 The patent application discloses a quantum digital signature-based mail system and sending and receiving method. In order to ensure the authenticity of the sent information, a specific signature algorithm ...
