COMMUNICATION PROGRAM, COMMUNICATION SERVER, MOBILE COMMUNICATION TERMINAL, AND COMMUNICATION METHOD

摘要

A communication system (900) is a system for enabling only a mobile communication terminal (103) to use a compressed dictionary content (112A) stored in the mobile communication terminal (103).The mobile communication terminal (103) transmits (901) its terminal identifier (802) to a communication server (101). The communication server (101) encrypts (902) a compressed parameter (113) by using the received terminal identifier (802) as a master key. The communication server (101) transmits (903) the encrypted compressed parameter (113A) to the mobile communication terminal (103). The mobile communication terminal (103) decrypts (904) the encrypted compressed parameter (113A) by using the terminal identifier (802). By using the decrypted compressed parameter (113), the compressed dictionary content (112A) is decompressed (905).
