"Communication system in ad hoc wireless terminal.Methods for decoding and encrypting a framework for broadcasting in a terminal, and to distribute a key for encryption of broadcasting in a second terminal, and program.Each terminal in a communication system in ad hoc wireless includes a table list of cryptographic key management (660).The table of the list of key management for encryption (660) stores, in association with a terminal identifier 661, such as a MAC address.An encryption key of unidifusu00e3o (662) for use in communication by unidifusu00e3o, with a terminal identified by the terminal identifier (661).And an encryption key broadcasting (663) used when the terminal identified by the terminal identifier (661) performs broadcast communication.Therefore, an encryption key is provided for each radio terminal that performs broadcast communication.And the encryption keys are managed by individual broadcasting terminal in a way independent and distributed.This allows independent and distributed management of encryption keys in a broadcasting communication system wireless ad hoc.
