The Smart Card Remote Unlocking Method and Its Implementation
In order to protect smart card from being misused and leaking out sensitive data, security mechanisms of locking after repeatedly retry will be introduced while designing chip operating system, with which the smart card will be automatically locked if it is threatened by illegal operations. This mechanism can not only prevent brute-force attack, but also trouble the users, for unlocking method should be provided to legitimate users after attacks or misuses. The security of traditional unlocking methods depends on the shared unlocking key between smart card and unlocking tool; once the unlocking tool is lost or comprised, security risks will be caused. The remote unlocking method proposed by this paper unifies the unlocking interfaces, manages the unlocking keys centrally and adopts a multiple-level and flexible model containing key management center, agent and users. This can significantly reduce the risks of key leakage and loss of control, and also has the features of controlling the unlocking operations, tracing operating staffs, auditing total usage and deploying flexibly.
