• The application of Elliptic Curve Cryptosystem has gained more and more attention. ECC uses smaller key size and lower memory requirement to retain the security level and can be a crucial factor in the smart card system. In this paper, an ECC based implementation of security schemes in smart card system to access control the door of some confidential places is proposed. The confidential place, for example a coffer, a strong room in the bank is used to store treasures as well as cashes, and where the mutual vigilance could be required. For the safety consideration, the going in and out a coffer by a person is not permissive but a group of authorized people. It involves the problem of secret sharing. The adopted solution of sharing secret is threshold scheme. Every participant possesses a secret shadow, which will be saved in the smart card. After correct reconstructing the shared secrets, it is permissible to access the coffer's door. For resisting dishonest participants, cheating detection and cheater identification will be included. The user can change his password of smart card freely and need not memorize his assigned lengthy password and shadow as traditional ID-based schemes makes our implementation much more user friendly.
