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.
