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.
摘要翻译：服务器和客户端在各个秘密信息保持单元中保存公用秘密信息。服务器中的服务器循环冗余校验（CRC）单元在将秘密信息添加到通信数据后生成CRC代码，并发送带有附加CRC码的通信数据。客户端CRC单元在将秘密信息添加到通信数据之后生成CRC码，并且检查通信路径中的通信数据中是否发生错误。由于客户端保存秘密信息，所以客户机确定没有发生错误，并获得通信数据。另一方面，不保存秘密信息的路由器不能获得通信数据。这样可以防止通信数据被传送到授权域之外的设备。

摘要： A content distribution system in which content transmission/reception is suppressed when there is a high risk of contents being stolen by a third party during communication. A content server acquires a communication distance indicating how far the content server is from a terminal in data communication. The content server conducts content transmission/reception when the communication distance is less than or equal to a predetermined value, and suppresses content transmission/reception when the communication distance exceeds the predetermined value.

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.
