【Abstract】 Chip Operating System (COS) is the manager of chip resources and the basis of security. We introduce a practical chip operating system MAXCOS, which is composed of transmission management, safety management, command management and file management. We deal with its design and implementation principles. Especially we emphasize its security structure, which includes the authentication between smart cards and terminals, the identification authentication of card holders, the security mechanisms for file access, the transmission of secure message and data cryptography.更多还原
