Abstract: A radio communication CPU (89) controls equipment by using network setting information in a network setting storage unit (86) of a radio communication device (3) included in a short-distance radio communication network so as to set up the connection relation with a communication network (for example, the Internet) and to control the transmission/reception of data between devices included in the communication network through the short-distance radio communication network. Thus, the network setting for connection to, e.g., the Internet for each portable device being present in the short-distance radio communication network is simplified.

Abstract: The input is enciphered by means of at least one of a sectoring circuit (13) used for processing the input data to generate recording signals, a scramble processing circuit (14), a header adding circuit (15), an error correcting/encoding circuit (16), a modulation circuit (17), and a synchronism adding circuit (18), and the enciphered signal is outputted. In addition to the key of the enciphering itself in the circuit, which circuit performs the processing, is also an enciphering key. Therefore, data are enciphered with a simple circuit structure and ciphered data are hardly deciphered.

Abstract: An optical disk (D) has a first working area and a second working area having two recording formats. Encrypted data is recorded on the second working area. Encrypting key data is recorded on the first working area. The encrypting key data is used for decoding the encrypted data. This recording technique makes easy reproduction of the recorded data quite difficult. If data recorded on a bit-formed portion can be reproduced by any means, the data signal recorded on the optical disk cannot easily be reproduced.
