摘要： An apparatus and a method for performing a hyperelliptic curve cryptography process at a high speed in a highly secure manner are provided. A base point D is produced such that the base point D and one or more of precalculated data in addition to the base point used in a scalar multiplication operation based on a window algorithm are degenerate divisors with a weight smaller than genus g of a hyperelliptic curve. An addition operation included in the scalar multiplication operation based on the window algorithm is accomplished by performing an addition operation of adding a degenerate divisor and a non-degenerate divisor, whereby a high-speed operation is achieved without causing degradation in security against key analysis attacks such as SPA.

摘要： An arithmetic processing device for inter-object data communication has an object manager for connecting objects so as to enable exchange of data between the objects, and a connection data supplying unit for supplying the object manager with connection data necessary for achieving the connection between the objects. Disclosed also are an inter-object communication method and a robot incorporating the arithmetic processing device. The robot may be designed to enable a user to replace parts thereof, thus changing the robot configuration. The robot preferably includes a part detection unit for detecting parts attached to the robot, and outputting a part detection result in accordance with the detection. An information storage unit stores information corresponding to the part detection result for each configuration obtained by replacement of the parts. A software changing unit revises robot-controlling software in correspondence with a changed configuration, based on a comparison of the part detection result with the information stored in the information storage unit. A controller controls general robot operations in accordance with the revised software.
