摘要： A folder containing at least one file can be created in a file storage (17) in response to a folder creation request from an owner (30) of an IC card (10), and an access authority to the folder can be set as an access control list (18A) of the folder in response to an access authority setting request from the owner (30). Then access to the file is controlled not only on the basis of the access authority to the file set by an issuer of a voucher (issuer of the file), but also on the basis of the access authority to the folder set by the owner (30).

摘要： Between an IC card (1) and a electronic ticket server (2), upon purchasing an electronic ticket a public key cryptosystem is employed for a mutual authentication to keep a strict security, and a shared secret between the electronic ticket and a ticket collecting machine is sent on a secure channel as well as the electronic ticket. Upon usage of the electronic ticket, the IC card (1) and the ticket collecting machine (6) mutually judge whether they carry out the mutual authentication by using a public key cryptosystem or a symmetric key cryptosystem. When they determine to use the symmetric key cryptosystem, they carry out the mutual authentication by using the shared secret exchanged beforehand. When they determine to use the public key cryptosystem, they carry out the mutual authentication by using the same method as that used upon purchasing the electronic ticket. This method of mutual authentication can dynamically switch cryptosystems for cryptographic communication between the IC cards or between the IC card and a tamper resistant device having an equivalent function to an IC card installed in related servers or the ticket collecting machine, based on their judgment of the types of bearers, the required degree of security and the required processing speed.

摘要： The object of the present invention is to prevent the fraudulent copying and creation of digital contents. A digital contents issuing system according to the present invention issues digital contents to be stored in an IC card 1. The digital contents issuing system comprises a first server 11 and a second server 3 configured to carry out an authentication regarding whether the first server 11 has the authority to execute a CREATE command or not. The first server 11 executes the CREATE command so as to create and store the digital contents in the IC card 1, when the first server 11 is authenticated, and found to have the authority.

摘要： In a token-ring-type local area network (LAN), a plurality of communication nodes are linked together into a ring by a transmission path, onto which a token used for obtaining a transmission right is circulating through and a frame carrying data is transferred through. Herein, the token has a first memory area for memorizing a ring priority, while the frame has a second memory area for memorizing a reservation priority corresponding to a data priority of the data owned by each communication node. When a current communication node receives the token, the frame is generated and transmitted therefrom without transmitting the token if the data priority is higher than the reservation priority. When the current communication node receives the frame, the data priority of the current communication node is written into the second memory area of the frame if the data priority is higher than the reservation priority. Transmission of the frame is stopped and thereby a new token is generated having the reservation priority of the frame when the data priority of the current node is lower than the reservation priority of the frame which is now transmitted from the current node and then recovered by the current node. Preferably, the frame of data can be transferred in the LAN based on the frame-division manner.
摘要翻译：在令牌环型局域网（LAN）中，多个通信节点通过传输路径链接在一起成为环，用于获得发送权的令牌正在其上传播，并且传送数据的帧被传送通过。这里，令牌具有用于存储环优先级的第一存储区域，而帧具有用于存储与每个通信节点所拥有的数据的数据优先级相对应的预留优先级的第二存储区域。当当前通信节点接收到令牌时，如果数据优先级高于预留优先级，则生成并发送该帧而不发送令牌。当当前通信节点接收到帧时，如果数据优先级高于预留优先级，则当前通信节点的数据优先级被写入到帧的第二存储器区域中。当帧的数据优先级低于现在从当前节点发送的帧的预留优先级，然后由帧的恢复时，帧的传输被停止，从而产生具有帧的预留优先级的新令牌当前节点。优选地，可以基于帧分割方式在LAN中传送数据帧。
