| 20090100524 | COMMUNICATION TERMINAL APPARATUS, SERVER TERMINAL APPARATUS, AND COMMUNICATION SYSTEM USING THE SAME - A communication terminal apparatus includes a storage section configured to store a library function in which a first specific instruction is executed a process to be executed prior to a communication with a communication target and a second specific instruction is executed before returning to a call source, a client application, an attribute value group of the client application, and an permissible address range of the first specific instruction. A communication instruction execution control section controls execution of a communication instruction based on the attribute value group of the client application, when the client application executes the communication instruction to generate an internal interruption. A security gate entering section checks whether or not an address of the first specific instruction is within a permissible address range when the client application executes the first specific instruction to generate the internal interrupt, and changes the attribute value group of the client application when the address of the first specific instruction is within the permissible address range. A security gate exiting section returns the attribute value group of the client application to an original state when the client application executes the second specific instruction to generate the internal interrupt. | 04-16-2009 |
