ABSTRACT:
A node terminal including an internal memory for saving a program transmitted from a server, a CPU for executing the program, a hash value calculating section for performing an operation of the program using a specified hash function when the execution of the program is completed, and a digital signature executing section for digitally signing the program operated using the hash function and the execution result of the program, using a secret key peculiar to the node and saved in a secret key storage, and a microprocessor capable of guaranteeing that the content of a memory is not unjustly falsified during the execution of the program.
