Abstract: Mobile storage device has brought the security problem of the sensitive data while enjoying the convenience brought by it. According to the requirement analysis of the security of mobile storage device, a Secure-Mobile Storage System(S-MSS) is designed. The key technology which the S-MSS involves is analyzed, such as the driver of mobile storage device, read-write of the disk sector, the mechanism of data encrypted storage and the strategy setting of virus protection. This paper gives a prototype system, which implements the encryption and protection to the data stored in the mobile storage device.

Key words: mobile storage device, security storage, data encryption, virus protection strategy
