Abstract
The present invention relates to an information processing apparatus by which a communication channel providing a high degree of privacy is established between a PDA and a data communication server. In the information processing apparatus, first, the PDA and a memory card are connected to each other, and perform mutual authentication. Data encrypted with a temporary key shared by the PDA and the memory card as a result of the authentication is transferred from the PDA to the memory card, decrypted by the shared temporary key, and then stored in the memory card. Next, a PC and the memory card are connected to each other, and perform mutual authentication. The data encrypted with a temporary key shared by the PC and the memory card as a result of the authentication is transferred from the memory card to the PC, decrypted by the shared temporary key, and then stored in the PC. Then, the PC and the data communication server are connected to each other, and perform mutual authentication. The data encrypted with a temporary key shared by the PC and the data communication server as a result of the authentication is transmitted from the PC to the data communication server via a broadband network.
