A public key certificate issuing system is disclosed which comprises a certificate authority for issuing a public key certificate used by an entity, and a registration authority which, on receiving a public key certificate issuance request from anyone of entities under jurisdiction thereof, transmits the received request to the certificate authority. The certificate authority, having a plurality of signature modules each executing a different signature algorithm, selects at least one of the plurality of signature modules in accordance with the public key certificate issuance request from the registration authority, and causes the selected signature module to attach a digital signature to message data constituting a public key certificate.

A communication device relates a plurality of identification information to specifying information included in the identification information and manages them, and thereby enhances easiness of identifying and specifying of a device of the other party and usability of a connection with the device of the other party. The communication device has an identification information reception part (a radio transmission/reception part, a baseband part and a control part), a storage part (a data base part) and an information processing part (a control part). The identification information reception part receives the pieces of identification information concerning the device of the other party to be connected, and in the storage part the pieces of identification information which are received are stored. The information processing part stores the pieces of identification information, which are received, in the storage part, and retrieves the identification information from the storage part by receiving input of the specifying information out of the pieces of identification information, and relates a result of that retrieval to the specifying information and outputs them, or makes that output possible. By this, it is possible to use the pieces of identification information related to the specifying information for specifying of the device of the other party and connection with it.

A spin injection magnetization reversal device is disclosed which inhibits an increase in resistance to enable multi-valued data recording. A ferromagnetic fixed layer and n groups each including a ferromagnetic free layer and an isolation layer are disclosed. The groups are disposed from the group including the first ferromagnetic free layer provided on the ferromagnetic fixed layer to the group including the n-th ferromagnetic free layer in the order. Each of the ferromagnetic free layers is preferably formed of one of a CoCrPt alloy, a CoCr alloy and a CoPt alloy with Pt or Cu concentration therein made monotonically decreased from the concentration in the first ferromagnetic free layer to that in the n-th ferromagnetic free layer.

A magnetic recording medium comprising a non-magnetic support, at least one primer layer formed on one surface of the non-magnetic support, comprising a non-magnetic powder and a binder resin, at least one magnetic layer formed on the primer layer, comprising a magnetic powder and a binder resin, and a back layer formed on the other surface of the non-magnetic support, wherein the magnetic powder contained in the uppermost layer of the magnetic layer is a rare earth metal-iron type magnetic powder of substantially spherical or ellipsoidal particles comprising a rare earth element and iron or a transition metal which comprises iron, and has a number average particle size of 5 to 50 nm and an average axis ratio of 1 to 2, and the total thickness of the magnetic recording medium is less than 6 μm. This magnetic recording medium can achieve an excellent block error rate.
摘要:
To provide an improved management structure of memory devices storing service-use applications. A card for a memory device applied to use various services is provided as one child card or more corresponding to each of the services, a parent card stores data for child-card issue management, and the child-card issue processing is executed based on the parent card, such as parent card authentication. An issue certificate having a parent-card digital signature is stored in the child card, the issue certificate contains a service code and a child-card identification, and thus it becomes possible to confirm a service set in the child card based on the issue certificate as the parent-card signature data.
