摘要： A storage device allows expanding user utilizable applications by storing information permitted to be read according to a certificate and information permitted to be read according to information determined by a user. An information distributor receives a certificate from the storage device and after verifying the certificate, transmits data of a license and access control conditions to the storage device. After receiving data of a certificate from an information browser, verifying the certificate and imposing a limit on access based upon one of access control conditions, the storage device transmits data of the license and the other to the information browser. The information browser permits utilization of the license under the limitation defined by the access control condition. The certificate includes either or both of a certificate approved by a certificate authority and a PIN (personal identifying number) determined by the user.

摘要： A memory card has: a flash memory chip for storing digital certificates and a seed of random numbers; a controller chip which can execute a managing process for managing the digital certificates and a random number generating process for generating the pseudo random numbers by using the seed of random numbers; and an IC card chip which can execute an authenticating process for authenticating personal identification information (PIN) inputted from a host apparatus and an encrypting process for encrypting the seed of random numbers. Thus, a processing time of security processes is reduced while assuring safety of the security processes.

摘要： A storage medium includes a storage device for storing information, information required for encryption and encrypted information, and an I/F device for inputting and outputting information, information required for coding and store encrypted information in a storage device or from an external apparatus other than the storage device, and an encoding device for coding of information and decoding of encoded information. When outputting information stored inside the storage device, information is encoded using encryption key information, and along with obtaining the encoded information and obtaining the encoded encryption key information by using another encryption key. Both the encoded information and encoded encryption key information are output so that decoding the information without the storage medium is impossible.

摘要： The external storage device according to the present invention which uses a non-volatile semiconductor memory such as a flash memory is provided with plural areas which store user data, and restricts access to the user data from a host computer and also dynamically changes an area an access to which is to be restricted. Accordingly, the ease of use of the external storage device for the host computer is improved. Specifically, the interior of the flash memory is divided into a normal area not protected by a password or the like and a protected area protected by a password or the like. A microprocessor controls accesses to the normal area and the protected area in accordance with a command from the host computer. In addition, the host computer can access the protected area after passing through authentication using a password. Moreover, the host computer changes information indicative of the location of the protected area, thereby dynamically changing the protection area.
