摘要： In a robot device, an action selecting/control system includes a plurality of elementary action modules each of which outputs an action when selected. An activation level calculation unit calculates an activation level AL of each elementary action on the basis of information from an internal-state manager and external-stimulus recognition unit and with reference to a data base. An action selector selects an elementary action whose activation level AL is highest as an action to be implemented. Each action is associated with a predetermined internal state and external stimulus. The activation level calculation unit calculates an activation level AL of each action on the basis of a predicted satisfaction level variation based on the level of an instinct for an action corresponding to an input internal state and a predicted internal-state variation predictable based on an input external stimulus.

摘要： A system and method for achieving secure and fast computation in hyperelliptic cryptography is realized. Fast scalar multiplication is achieve by executing computing operations including halving as computing processing in scalar multiplication with respect to a divisor D in hyperelliptic curve cryptography. For example, computing operations including halving are executed in scalar multiplication with respect to a divisor D on a hyperelliptic curve of genus 2 in characteristic 2 having h(x)=x2+x+h0, f4=0 as parameters, a hyperelliptic curve of genus 2 in characteristic 2 having h(x)=x2+h1x+h0, f4=0 as parameters, or a hyperelliptic curve of genus 2 in characteristic 2 having h(x)=x as a parameter. Further, reduced complexity and faster computation are realized through the application of a table that records which of k1, k1′, (k0, k0′) is correct on the basis of a computed value of [½iD] with respect to a fixed divisor D, and through a reduction in the number of inversion operations.

摘要： A secret communication and authentication scheme based on a public key cryptosystem in which a decryption speed is improved while maintaining a security level. In the RSA type secret communication, a plaintext is expressed in a form of a k-digit base n number and a ciphertext is obtained by applying a calculation using the first public key n and the second public key e to the base n number and transmitted. Then, from the received ciphertext, a lowest digit of the base n number is decrypted by using the first public key n and the second secret key d, upper digits of the base n number are sequentially decrypted by using a decrypted value of the lowest digit of the base n number at the receiver side, and the plaintext is recovered by using decrypted values of respective digits of the base n number. The Rabin type secret communication can also be realized by the similar scheme. Moreover, the same principle of the base n pubic key cryptosystem can also be used in realizing the RSA type or the Rabin type Authentication.
