Equipment identity authentication system, method and device applied to oil storage system

The invention provides an equipment identity authentication system, method and device applied to an oil storage system. The equipment identity authentication system applied to the oil storage system comprises a background management system, master equipment and slave equipment. The equipment identity authentication system, method and device applied to the oil storage system have the advantages that the identity authentication of the equipment is realized, and the access security of the equipment is ensured. The equipment authentication is completely realized by using a domestic cryptographic algorithm, so that the safety and reliability of the system are ensured at the algorithm level. Only a national cryptographic algorithm SM3 is used in equipment authentication. The HMAC-SM3 algorithm is also implemented by executing the SM3 hash algorithm for two times. Therefore, a cipher module does not need to integrate too many cipher algorithms, and especially for the slave equipment, the scale, overhead and cost of
