Abstract: A user device uses, instead of agreement information, only second session information contained in the agreement information, to generate an electronic signature for information containing the session information and information indicating an abort request, and outputs abort request information containing the session information, the information indicating the abort request, and the electronic signature, whereby transmission/reception can be performed without unnecessary information. Similarly, it may be configured to use only the second session information to generate an electronic signature for information containing the session information and information indicating a commitment request, and to output commitment request information containing the electronic signature. Since a third-party device defines a third session state as abort in correspondence to the second session information, it is able to manage states while appropriately discriminating a plurality of concurrent electronic value exchanges.

Abstract: In a mobile terminal that performs transmission and reception of a message between an IC card and a terminal program, the security is improved by preventing an imposture of a source of a message or an interception of a message. A mobile terminal comprises an IC card and a terminal program. The terminal program generates a program identifier (i1:1) from a domain ID “i1” of the IC card and a port number “1” that can be updated in the IC card. Then, a message is transmitted, the source ID of which is the program identifier and the destination ID of which is the identifier “i1:0” of the IC card. Upon receipt of the message, the IC card collates the domain ID with the domain ID that the IC card has, as to the source ID. When they coincide, processing in accordance with the contents of the above-mentioned message is performed.

Abstract: When a portable terminal receives a condition for an exchange object from a portable terminal, it selects electronic values as exchange objects, out of lists constituting the condition. An IC card deletes the electronic value and sends a message addressed to the portable terminal. An IC card deletes the electronic value in conjunction with fulfillment of a predetermined condition and thereafter sends a message addressed to the IC card. The IC card stores the electronic value in conjunction with fulfillment of a predetermined condition and sends a message addressed to the IC card. The IC card stores the electronic value.

Abstract: The security of an IC card is improved by managing success and failure in authentication individually for each terminal program. An IC card includes a random number generation section, a source authentication section, and a process execution section. Upon receipt of a message of type “1”, the random number generation section generates a random number n, and stores it in a random number storage section by associating the random number n with a source included in the message. Upon receipt of a message of type “2” from the source and in a case where the random number n corresponding to the source is stored, the source authentication section collates a value m calculated from an authentication key held by the IC card and the random number n with a value m included in the message of type “2”. When both values agree, upon receipt of a message of type “3” from the source, the process execution section executes a process in accordance with a type of the message.
