Mobile Storage Device Embedded Encryption System Design Zhang Zuying （Nanjing college of chemical technology，Nanjing ,210048 ） Abstract：Through doing research on USB2.0 interface technology and hardware encryption technology, this thesis designed and realized a encryption storage adaptor based on USB2.0 interface. This thesis is for designing system hardware and firm ware. USB2.0 interface chip CY7C68013 of Cypress company is the core part of hardware. Centering on CY7C68013, this paper designed the outline of hardware, further to partly design in detail of periphery circuit, then complete the design of hardware theory outline, and briefed on the firmware design process.
