Abstract

The invention provides a post quantum cryptography communication method, which comprises the following steps that: a sender encrypts a signature through a first random number, encrypts the first random number through a private key of the sender, encrypts a message to be sent according to a message encryption key generated by a second random number, encrypts the second random number according to a key encryption key generated by the third random number, and sends the encrypted datato a receiver; and the receiver obtains the second random number through the key encryption key generated by the third random number, obtains a message through the second random number, obtains a public key of the sender through a public key pointer random number of the sender, obtains a first random number through the public key of the sender, obtains a signature through the first random number, and performs verification according to the message, the public key and the signature. According to the post quantum cryptography communication method provided by the invention, message transmission communication and digital signature authentication are realized, and the risk that a key is stolen or cracked by a quantum computer is reduced.

Description

technical field [0001] The invention relates to the technical field of secure communication, in particular to an anti-quantum computing encrypted communication method. Background technique [0002] With the outbreak of the information revolution in the 21st century and the continuous development of science and technology, how to ensure the secure communication between clients is a current research hotspot. To achieve information security such as data encryption, transmission and privacy, whether it is an enterprise company that conducts daily business activities, or a government agency, bank, etc., there is an urgent need for this, especially in today's globalized economic era, to ensure the unconditional security of information , is one of the focuses of current public attention. It was first proposed that the transmission of communication information between clients is almost all plaintext information, which is very easy to be eavesdropped and has low security. Later, peo...
