    摘要: According to one embodiment, a device includes first and second data generator, a one-way function processor, and a data output interface. The first data generator generates a second key by encrypting a host constant with a first key in AES operation. The second data generator generates a session key by encrypting a random number with a second key in AES operation. The one-way function processor generates authentication information by processing secret identification information with the session key in one-way function operation. The data output interface outputs the encrypted secret identification information, a family key block, and the authentication information to outside of the device.

    摘要: According to one embodiment, a semiconductor memory device includes a memory which comprises an area accessible from outside and a confidential information area storing confidential information and a set flag. A controller reads the flag from the memory when instructed to erase data in the confidential information area, determines whether the flag is set, erases data in the confidential information area when the flag is clear, and abandons process requested by the data erase instruction when the flag is set. An authenticator uses data in the confidential information area to execute operation for authentication.

    摘要: In a wireless communication terminal, the other terminal existence confirmation section broadcasts a confirmation message at fixed intervals and receives a response message. The topology information management section computes the topology of the whole network to which the wireless communication terminal itself belongs, on the basis of the topology information on the network received at fixed intervals from other terminals. The path management section derives an optimum path to the terminal of the transmission destination. The QoS information collection section issues a communication start request instruction and, when a QoS information collect request instruction has been issued, unicasts a QoS request packet on the path and receives a reply QoS request packet. The judgment section adopts the path as the communication path when QoS information satisfies a predetermined quality standard.
