摘要： An optical fiber monitoring system monitors an inter-building optical fiber connecting a first building and a second building. The optical fiber monitoring system includes a first visualization panel provided in the first building and optically connected to an one end of the inter-building optical fiber, a second visualization panel provided in the second building and optically connected to an other end of the inter-building optical fiber, and a monitoring light source provided in the first building to input a monitoring light into the inter-building optical fiber. The first visualization panel includes a first photosensor that partially leaks the monitoring light inputted into the inter-building optical fiber from the monitoring light source and detects an amount of a leaked light. The second visualization panel includes a second photosensor that partially leaks a light from the inter-building optical fiber and detects amount of a leaked light.

摘要： A storage device sends its storage-device-specific information A to a client apparatus. The client apparatus generates an encryption key P1, using client-apparatus key generation information B1 specific to the client apparatus and the received information A. The client apparatus generates information D′ by encrypting its client-apparatus-specific information D, using the encryption key P1, and sends the information D′ to the storage device. The storage device stores the information D′. When the storage device authenticates a client apparatus, the storage device has the client apparatus generate information D′ through the process as described above and judges whether or not the information D′ stored in the storage device matches the information D′ generated by the client apparatus being examined.
