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\u2019s 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.<\/jats:p>","DOI":"10.3390\/s91109300","type":"journal-article","created":{"date-parts":[[2009,11,19]],"date-time":"2009-11-19T12:39:06Z","timestamp":1258634346000},"page":"9300-9331","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["The Development of a Portable Hard Disk Encryption\/Decryption System with a MEMS Coded Lock"],"prefix":"10.3390","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4515-7955","authenticated-orcid":false,"given":"Weiping","family":"Zhang","sequence":"first","affiliation":[{"name":"Key Laboratory for Thin Film and Microfabrication of Ministry of Education, National Key Laboratory of Nano\/Micro Fabrication Technology, Research Institute of Micro\/Nano Technology, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenyuan","family":"Chen","sequence":"additional","affiliation":[{"name":"Key Laboratory for Thin Film and Microfabrication of Ministry of Education, National Key Laboratory of Nano\/Micro Fabrication Technology, Research Institute of Micro\/Nano Technology, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jian","family":"Tang","sequence":"additional","affiliation":[{"name":"Key Laboratory for Thin Film and Microfabrication of Ministry of Education, National Key Laboratory of Nano\/Micro Fabrication Technology, Research Institute of Micro\/Nano Technology, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peng","family":"Xu","sequence":"additional","affiliation":[{"name":"Key Laboratory for Thin Film and Microfabrication of Ministry of Education, National Key Laboratory of Nano\/Micro Fabrication Technology, Research Institute of Micro\/Nano Technology, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yibin","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory for Thin Film and Microfabrication of Ministry of Education, National Key Laboratory of Nano\/Micro Fabrication Technology, Research Institute of Micro\/Nano Technology, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shengyong","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory for Thin Film and Microfabrication of Ministry of Education, National Key Laboratory of Nano\/Micro Fabrication Technology, Research Institute of Micro\/Nano Technology, Shanghai Jiao Tong University, Shanghai 200240, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2009,11,19]]},"reference":[{"key":"ref_1","unstructured":"Netac technology Co., Ltd.
