| Abstract: | Based on the insufficiency of existent secret USB disks,an method of hardware designing for secret USB disk is presented,which integrates data encryption/decryption,passwords authentication,attack counteraction.It can well protect arithmetic and encryption/ decryption key,destroy data automatically while over times or overdate.Security model and framework model are introduced,the details of the design and implementation in USB interface control part,encryption/decryption,security chip operation are introduced emphatically.Finally,the security performance of the secret carrier design is analyzed from encryption policy and key security. |
