摘要： A content management system which can prevent a content from being copied exceeding the limited number of copies for the content. The content management system includes a first content management device and a second content management device. The first content management device stores period information that indicates an available period during which a first external device is permitted to use a copied content which has been copied from the content, and outputs the period information to the second content management device when the content is moved. Upon receiving the period information from the first content management device, the second content management device judges whether the available period of the copied content has expired, using the received period information, and if it is judges that the available period has not expired, it inhibits the content from being copied to the second external device.

摘要： To aim to provide an information security device capable of reducing a period necessary for performing a power operation used for secret communication or authentication. The information security device performs secret communication or authentication by calculating an exponentiation X^d based on target data X and a secret value d using the window method. In the process of calculating the exponentiation X^d, immediately after square of a random value R acquired for multiplication is repeatedly performed a predetermined number of times, for example 256 times, a result of square of the random value R is cancelled using a cancellation value S (=R^(−2^256)). This makes it unnecessary to perform cancellation processing that has been conventionally performed.

摘要： In the telemedical system securely sharing encryption keys for enabling secure exchange of the encrypted biological data between the measurement terminal and the server to prevent the data from being stolen by the malicious third party, a service key is transferred to the second adapter attached to a measurement terminal from the server via the first adapter attached to the management apparatus. First, the first adapter attached to the management apparatus receives the service key from the server. Next, the first adapter is temporarily detached from the management apparatus and is attached to the measurement terminal to store the symmetric key. The first adapter is detached from the measurement terminal, and is attached to the management apparatus again. The service key received in the first adapter is encrypted using the symmetric key, and the encrypted key is transmitted to the second adapter attached to the measurement terminal.

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 group formation/management system rigidly sets a group range, allows contents to be used freely among member devices in the group, and includes one or more registered member devices for holding common secret information unique to the group, a new member device for transmitting a request for registration in the group and receiving and holding common secret information, and a group management device for receiving the registration request from the new member device and, when the number of registered member devices is less than the maximum number of registerable member devices, outputting the common secret information to the new member device. Furthermore, because member devices are authenticated using the common secret information when contents are to be used, and contents are only delivered if the authentication is successful, member devices that do not hold the common secret information (i.e. unregistered member devices) can be prevented from using contents.

摘要： The present invention aims to provide a time authentication device for distinguishing clocks that show a time falling within the predetermined permissible range as compared with a time shown by the time authentication device. In a time authentication device embodied as a distribution device 11, a time-relation information storage unit 104 stores a playback-device-time measured by a clock unit 203 of a playback device 12, and also stores a distribution-device-time measured by a clock unit 103 when the playback-device-time is acquired. The time authentication unit 107 acquires from the playback device 12 a target time measured by the clock unit 203, and also acquires an authentication time measured by the clock unit when the target time is received. The time authentication unit 107 then calculates a first difference (=Authentication Time−Distribution-Device-Time), a second difference (=Target Time−Playback-Device-Time), an authentication difference (=First Difference−Second Difference). If the authentication difference is smaller than or equal to a predetermined threshold, the time authentication unit 107 judges that the clock unit 203 of the playback device 12 is valid.
