Summary: | The invention provides an industrial internet of things certificateless lattice-based authentication key negotiation method and system, and the method comprises the steps: in a setting stage, a key generation center generates a public parameter through employing a given security parameter according to the requirement that a non-homogeneous small integer solution problem on a lattice is difficult to solve, and generates a main public and private key pair; in the secret key generation stage, the equipment selects a secret value, then a secret key generation center extracts part of private keys for the equipment, and finally a public and private key pair of the equipment is formed; in the key negotiation stage, the two devices complete authentication through two rounds of interaction and negotiate to generate a session key. According to the method, the security problem of certificate management and key escrow is solved based on the certificateless password, and meanwhile, the security of the scheme is ensured by |
