    Abstract: PROBLEM TO BE SOLVED: To make it possible to incorporate a public key type authentication active mechanism in an application deploying a number of chips in a wired logic chip.
    SOLUTION: An input parameter includes a public key p in a process in which a pseudo random number so called a probability variable r unique to transaction is generated by a chip using a pseudo random number generator 7, a process in which the parameter is connected to the probability variable r by a mathematical relation formula, and is stored in a data memory of a chip in a process in which a parameter x is transmitted from the chip to the application, a process in which a serial function 10 has the probability variable r unique to the transaction and a private key s as input parameters, and a parameter y composes an authentication value V in a process in which the parameter y is calculated using the serial function 10, and a process in which the authentication value V is confirmed by the application.

    Abstract: PROBLEM TO BE SOLVED: To provide a technique related to a communication system that is not affected by a change of an IP address of a mobile node and the operation thereof is stabilized.SOLUTION: An application program 410 is operable to provide a communications session using an internet protocol address information. An operating system 420 is operable to monitor the internet protocol address information and to inform the application program of a change of internet protocol address information. The application program is arranged to adapt the communications session in accordance with the change of internet protocol address information. As a result of the operating system informing the application program of a change of the internet protocol address information, the application program can adapt the operation of the communications session to reduce a likelihood of the communications session being affected when the IP address changes.
