摘要： The present invention provides a password recovery system that re-supplies a password to only the legitimate user of the password. The password recovery system includes a memory card with CPU and a mobile phone. When a password needs to be recovered, a phone call is made, to the mobile phone, from a telephone connected to a phone line whose phone number is registered in advance into the memory card with CPU. The mobile phone then obtains the telephone number of the phone line via a caller's telephone number notifying service. It is judged whether the obtained telephone number and the registered phone number are the same, and when they are the same, the password stored in the memory card with CPU will be re-supplied so that the user can recover it.

摘要： An information distribution system is composed of: an information distribution device that transmits advertisement information issued by an information provider; a communication terminal that receives the advertisement information and sends the received advertisement information to a memory card; the memory card that is portable and mountable on the communication terminal. The memory card is provided to the user at a cost borne by the information provider at least partly, and includes a storage unit having an area for storing advertisement information, a judging unit for judging whether the received advertisement information is issued by the information provider, and a writing unit for writing the received advertisement information if judged to be issued by the information provider. The information distribution system enables a memory card provider to provide a memory card to a user at no or lower cost than would otherwise be fully payable by the user.

摘要： A revocation list generation apparatus and a revocation judgement apparatus suppress the size of a CRL even if a number of public key certificates to be revoked increases.The revocation list generation apparatus, in which leaves in a tree structure correspond to public key certificates, which are identified by leaf identifiers, and nodes from a leaf that corresponds to a revoked public key certificate to a root are revoked, generates, for each revoked node excluding leaves, revocation information showing whether directly subordinate nodes are revoked, and generates a revocation list that includes a plurality of pieces of revocation information arranged in an particular order.The revocation judgement apparatus obtains the revocation list, attempts to construct a path from the root to the leaf, using the revocation information in the revocation list, and when the leaf is included in the constructed path, judges the obtained public key certificate is revoked.

摘要： In an information input/output system, a user device inputs and outputs information to and from external sources including a key management device. The system includes the key management device that securely outputs encrypted certificate revocation list (CRL) information specifying an invalid device unit that has been made invalid for use, and the user device that includes an input/output unit and a host unit. Via the input/output unit, input and output of information is enabled between the host unit and the external sources. The host unit securely receives, via the input/output unit, the encrypted certificate revocation list (CRL) information outputted by the key management device and judges whether the input/output unit is an invalid device unit.
