Abstract
The present disclosure relates to a security locking device of computers having separate key pairs, and including an encryption board inserted between a main board and a hard disk, and an encryption board being inserted into the encryption board to perform a real-time authentication process. The electronic key and the encryption board performs the real-time authentication process and hardware anti-copy self-testing process, and encrypt the data communicated between the encryption board and the electronic key. After passing the authentication process and the hardware anti-copy self-testing process, the electronic key combines an internally stored key list with the key list on the encryption board, and selects a user key to encrypt/decrypt the data on the disk according to the partition of the hard disk where the encrypted data is written to. The security locking device can assure the safety of the data, and the hardware is prevented from being copied.
