However, it is still possible that the key can be broken because the key is usually stored in special sectors of the hard-disk or USB's flash. The security of hardware-based hard-disk encryption/decryption is higher than that of the software-based hard-disk encryption/decryption. Usually, the key is stored in special sectors of the hard disk or USB's flash in both of software-based and the hardware-based encryption/decryption system.

The E906 portable hard-disk of the EAGET company, the P681 portable hard-disk of the Agio company and the Drive trust hard-disk of Seagate company use the hardware encryption/decryption method. This method needs less computer resources. The hardware-based method uses special chips to accelerate the encryption/decryption process.

The K210 portable hard disk of Netac Technology Company, NetDisk Mini portable hard disk of Ximeta Company and Truecrypt Foundation use the software encrypted/decryption method. But this kind of method has some disadvantages: (1) The encryption/decryption software can easily to be monitored by a Trojan program (2) The instructions of the encryption/decryption are executed by the CPU, which will consume more computer resources (3) It is difficult to transfer the encryption/decryption software among different operating systems. The software-based method uses the computer's CPU to perform encryption/decryption tasks. There are mainly two encryption approaches to protect the data in the portable hard disk: the software-based method and the hardware-based method.

As more and more important data is stored in portable hard disks, how to protect the data has become a hot issue. Various security threats, such as the malicious data modification, data leaks and the stolen hard-disk events, may cause inestimable loss to some organizations, such as the military, governments and enterprises.

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. 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. The whole prototype was fabricated and tested. 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 ATA protocol circuit, the MEMS control circuit and AES encryption/decryption circuit are designed and realized by FPGA(Field Programmable Gate Array). 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. 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.
