  • Publication number: 20090093244
    Abstract: A communication system limits use of compressed dictionary content stored in a mobile communication terminal to only the mobile communication terminal. The mobile communication terminal transmits terminal identification information to a communication server. The communication server uses the received terminal identification information as a master key to encrypt compression parameters and transmits encrypted compression parameters to the mobile communication terminal. The mobile communication terminal decrypts the compression parameters encrypted using the terminal identification information and uses the decrypted compression parameters to decompress the compressed dictionary content.
