AB  - In this paper, a novel portable hard-disk encryption/decryption system with a 
      MEMS coded lock is presented, which can authenticate the user and provide the key 
      for the AES encryption/decryption module. The portable hard-disk 
      encryption/decryption system is composed of the authentication module, the USB 
      portable hard-disk interface card, the ATA protocol command decoder module, the 
      data encryption/decryption module, the cipher key management module, the MEMS 
      coded lock controlling circuit module, the MEMS coded lock and the hard disk. The 
      ATA protocol circuit, the MEMS control circuit and AES encryption/decryption 
      circuit are designed and realized by FPGA(Field Programmable Gate Array). The 
      MEMS coded lock with two couplers and two groups of counter-meshing-gears (CMGs) 
      are fabricated by a LIGA-like process and precision engineering method. The whole 
      prototype was fabricated and tested. The test results show that the user's 
      password could be correctly discriminated by the MEMS coded lock, and the AES 
      encryption module could get the key from the MEMS coded lock. Moreover, the data 
      in the hard-disk could be encrypted or decrypted, and the read-write speed of the 
      dataflow could reach 17 MB/s in Ultra DMA mode.
