Bidirectional authentication method and device for storage system access based on hardware information

The invention provides a bidirectional authentication method and a bidirectional authentication device for storage system access based on hardware information. The method comprises the following steps: acquiring a host and stored hardware information and respectively storing the hardware information in an opposite-side system; enabling the host access memory to calculate a host hardware identification code according to the Hash value of the hardware information of the host access memory, generate a host authentication packet with the authentication information and send the host authentication packet to the memory for comparison, and when the comparison is not passed, refusing the host access; calculating a storage hardware identification code from the storage hardware information, putting the storage hardware identification code into a storage authentication packet, sending the storage authentication packet to a host for comparison, and abandoning access to storage when the comparison does not pass; and obtai
