摘要:
An information processing device includes a scalar multiplication operating unit calculating, based on a point P on an elliptic curve E defined on a predetermined defined field, a point Q=s·P by scalar-multiplying the point P and an operation verifying unit verifying whether an equation (P+Q)+G=P+(Q+G) holds by using the point P on the elliptic curve E, the point Q=s·P calculated by the scalar multiplication operating unit, and an arbitrary point G on the elliptic curve E.

There is provided a power management apparatus including an authentication processing unit that carries out an authentication process on each individual electronic appliance that is to be managed, a consumption amount acquiring unit that acquires information on power consumption from the electronic appliance, and an information display unit that displays an authentication state or an authentication result obtained from the authentication processing unit, together with the information on power consumption acquired by the consumption amount acquiring unit.
摘要:
There is provided a power management apparatus including: a managed appliance registering unit carrying out authentication on an electronic appliance connected to a power network and registering the electronic appliance as a managed appliance if the authentication has succeeded; and a control unit controlling operation of and supplying of power to the managed appliance. The managed appliance registering unit is operable, when an electronic appliance registered in another power management apparatus is connected to the power network, to acquire, from the electronic appliance, a digital signature, which has been assigned to identification information that is unique to the electronic appliance by the other power management apparatus, and identification information that is unique to the other power management apparatus, and is operable when verification of the digital signature assigned by the other power management apparatus has succeeded, to temporarily register the electronic appliance registered in the other power management apparatus.

There is provided a power management apparatus including a game service providing unit providing, to an electronic appliance, a service using game contents whose theme is power. The game service providing unit includes a game control unit controlling execution of the game contents, a real world constructing unit constructing a setting of a game reflecting a real-world environment, based on managed appliance information stored in a database, and a virtual world constructing unit constructing a setting of the game reflecting a virtual environment, based on a setting set in advance in the game contents. The game control unit is operable to initialize the game contents by combining the setting of the game constructed by the real world constructing unit and the setting of the game constructed by the virtual world constructing unit.
