摘要:
A structured document signature device includes an adaptation policy associator configured to associate each element forming a structured document with an adaptation policy indicating an action which can be adapted to a child element of the element or a value of the element; a hash tree constructor configured to insert a hash value of the child element of the element or a hash value of the value of the element into the structured document as an attribute value of the element, and to construct a hash tree including the hash value; a digital signature adder configured to add a digital signature to a root of the hash tree and the adaptation policy; and an output configured to output the structured document and the digital signature.

A multi signature verification system adds new additional data to original data with a signature attached thereto and verifies validity of the original data and the additional data. The system includes an electronic signature attaching apparatus including an electronic signature attaching unit attaching an electronic signature to original data previously created, acquired trapdoor hash value, and identification information, a data addition apparatus, and an electronic signature verification apparatus.

The present invention provides a communication terminal, a billing apparatus, a service providing apparatus, and a program all of which operate when a service is provided via communications, to enable a billing process based on diversified billing rules to be accomplished without increasing loads on network facilities. A billing rule acquiring function 1011 of a communication terminal 100 receives a first billing rule for a communication charge required to distribute service information, from a billing server 200. The billing rule acquiring function 1011 receives, from a service providing server 300, metadata containing second billing information individually set for service information. A communication history recording section 106 records a communication history when service information is received via a communication network. A billing information generating section 110 generates billing information on provision of a service on the basis of the billing rule information and communication history.

摘要:
An access controller controls access to control target resources by a program. The access controller includes a function access detection unit and a resource access control unit. The function access detection unit detects loading of a control target function from the program and generates identification information to specify an access request issued from the detected control target function. The resource access control unit obtains a request of accessing the control target resources from the program and determines permission of the access request based on the identification information.
摘要:
A communications terminal apparatus, a reception apparatus, and a method can enhance the effect of reducing the amount of information to be transmitted when text data is generated and transmitted. The communications terminal apparatus 100 stores key identifier definition information in a key identifier definition-storage area 1071. The communications terminal apparatus 100 obtains a key identifier corresponding to an operated key from the key identifier definition-storage area 1071 when the key is operated, and adds and stores it as a key identifier string in the input key identifier storage area 1073. The communications terminal apparatus 100 transmits the key identifier string stored in the input key identifier storage area 1073 by the transmission function 1031 when a transmit instruction is detected.

摘要:
A communication terminal device includes a wireless communication unit, an integrity measurement request unit, a cryptographic processing unit, a pointing unit. The integrity measurement request unit generates a command to request another computer device to measure integrity. The cryptographic processing unit performs cryptographic processing concerning communication with the another computer device. The pointing unit acquires positional information when a result of the integrity measurement satisfies a predetermined condition.
