摘要： PROBLEM TO BE SOLVED: To allow communication to be performed by using a more appropriate electronic certificate even when the communication using any of a plurality of electronic certificates fails in a communication device having the plurality of electronic certificates.SOLUTION: When authentication processing performed by using any of a plurality of client certificates stored in a client certificate region fails (YES at a step 190), the plurality of client certificates other than the client certificate used at the time of failure is set as transmission certificates (a step S250), and the authentication processing is performed again by using the transmission certificates. Thus, when an electronic certificate capable of performing communication is included in a plurality of electronic certificates, there is a possibility that the communication might succeed by using the certificate and the communication might be able to be performed by using the appropriate electronic certificate.

摘要： PROBLEM TO BE SOLVED: To simply and accurately emulate a peripheral equipment, such as a hard disk, connected to an execution machine from a target machine. SOLUTION: A continuous empty area is reserved in the hard disk 84 connected to the execution machine as a virtual PC system file area using a file system of the execution machine. The content of the virtual PC system file is formatted to be as close as a hard disk recognized by the virtual PC as a target machine. When power is turned on, a BIOS of a DOS/V machine is developed, and a processing is transferred to an emulation apparatus when a device driver is read in, and a kernel and modules are developed. When a hard disk emulator HDM is incorporated, partitions are rearranged, and an address offset of the hard disk is written into a disk information block to be provided to accesses in emulation. Peripheral equipments are also accessed with use of both BIOS's by switching tasks. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To allow status information of a communication apparatus to be notified when authentication processing fails by a system in which the communication apparatus is disconnected from a network at the time of a failure in authentication.SOLUTION: A communication apparatus executes authentication processing according to IEEE 802.1X serving as a standard in which the communication apparatus is disconnected from a network at the time of a failure in authentication for connecting the communication apparatus to the network (steps S130 and S140), sequentially determines whether or not a plurality of predetermined check items concerning the authentication processing are right during the authentication processing and diagnoses error contents on the basis of the check items determined to be wrong. Further, when there is an error and the authentication processing fails (YES at a step S150), the communication apparatus notifies of the error contents not-through the network by printing the diagnosed error contents as a status sheet on a medium (a step S160). As a result, even if the authentication processing fails and the communication apparatus is disconnected from the network, status information of the communication apparatus can be notified.
