Anti-quantum digital signature encryption method based on post-quantum PoW

The invention belongs to the technical field of network security, and particularly relates to an anti-quantum digital signature encryption method based on post-quantum PoW. Generating a pair of public key and private key for the user by using a Rainbow signature algorithm, generating an address of the user according to the public key, and storing the public key and the address in a public key storage server in a network by the user; a user initiates a data request, and the initiated data request is signed and broadcasted by using the private key; the user sends the data request to the public key storage server according to the address in the broadcast of the received data request; the public key memory feeds back a public key to the corresponding user according to the received address; the user verifies the data request according to the received public key, if the verification is passed, the node initiates a consensus, and after the consensus succeeds, the successfully competed user generates a block for the
