    摘要： It is aimed to prevent access to data when a storage device 1 is lost without damaging security and convenience of a user even if the storage device 1 is under condition in which communication with an authentication server is unavailable and further a personal identification number is leaked. The storage device 1 includes a data storing unit 11 which stores security target data and valid duration of use data showing a valid duration of use of the security target data and a validity checking unit 14 which implements a validity check process for checking if the security target data stored in the data storing unit 10 is valid based on the valid duration of use data stored in the data storing unit 10. Then, when the communication with the authentication server is unavailable, access to the data is controlled by implementing the validity check process.

    摘要： A method securely communicates data between members of a group of mobile devices using a wireless channel. The members include a group leader. Each member is associated with a physical token. Each member and associated token stores a binding key. Each member also stores an identification. A session key is stored by the group leader. Each token generates a member key, which is encrypted with the binding key and transmitted to the member where it is decrypted and stored. The session key is distributed securely to each member. Each member key is securely passed to the group leader. Then, data to be communicated between the group leader and a particular member can be encrypted using the using the associated member key of the particular member and the session key.

    摘要： It is an object to provide a method for invalidation and new registration of a storage medium, a method for backup of data stored in a storage medium and for restoration of backup data to a storage medium, and a method for encryption of and application of an electronic signature to data to be backed up, and for decryption of backup data to be restored and verification of a signature. A service device includes a reception unit for receiving a request for data processing regarding a storage medium from a communication terminal device connected to the storage medium, an authentication unit for performing authentication of whether or not the storage medium connected to the communication terminal device is valid, and a database for storing a public key of the storage medium, wherein, when the reception unit receives a request for invalidation of the first storage medium from the communication terminal device, and the authentication unit authenticates the second storage medium connected to the communication terminal device as a valid storage medium, the database deletes the public key of the first storage medium stored in the database.
