    摘要： Resistance against simple power analysis is maintained while a smaller table is used. An IC card 100 decrypts encrypted information using elliptic curve calculation for calculating a point k*C by multiplying a point C on an elliptic curve E with a coefficient k that is a positive integer less that a prime p. The calculation of the point k*C is performed by adding a multiplication result obtained by multiplying a digit position (window) value w of the acquired coefficient k with the point C in a position corresponding to the digit position, and is performed with respect to all digit positions. When a non-negative integer t exists that fulfills a condition that the acquired digit value w_can be divided by 2t and cannot be divided by 2t+1, the multiplication includes adding a point obtained by multiplying a point Q with w/2t.

    摘要： An authentication system, including a service use device 1 which presents blurred information obtained by blurring certification information desired to be certified, service providing devices 3a to 3c which verify the validity of blurred information presented by the service use device 1, and an authentication device 2 which supports the service use device 1 to issue valid blurred information. The authentication device 2 adds a digital signature to information including certification information and blurred information, and generates authentication information including the obtained digital signature, certification information, and blurred information (S2). The service use device 1 generates, based on the authentication information generated in the authentication device 2, blurred authentication information including blurred information selected according to an instruction from a user, instruction information representing the instruction, and a digital signature (S4). The service providing devices 3a to 3c verify the validity of blurred information indicated by instruction information included in the blurred authentication information generated by the service use device 1, based on the digital signature included in the blurred authentication information (S6).

    摘要： Provided is a health care system including a key management server that receives from a server a request for a decryption key, with first identification information identifying a measuring apparatus, second identification information identifying vital sign data, and third identification information identifying the server. The key management server generates the decryption key using the first identification information, and stores fourth identification information identifying a server predetermined as a destination of the decryption key, and fifth identification information indicating the category of the vital sign data in correspondence with the fourth identification information. The key management server transmits the decryption key to the server, when the received third identification information matches the fourth identification information, and the received second identification information matches the fifth identification information.

    摘要： A server and a client hold common secret information in respective secret information holding units. A server Cyclic Redundancy Check (CRC) unit in the server generates a CRC code after adding the secret information to communication data, and transmits the communication data with the CRC code attached. A client CRC unit of the client generates a CRC code after adding the secret information to communication data, and checks whether or not an error has occurred in the communication data on the communication path. Since the client holds the secret information, the client determines that an error has not occurred, and obtains the communication data. On the other hand, a router, which does not hold the secret information, is unable to obtain the communication data. This prevents the communication data from being transferred to devices outside an authorized domain.
