<p>A wireless data communication device for performing a short-distance wireless data communication. The device comprises an infrared communication section, a CPU, a memory, an encryption/ decryption unit, and a wireless communication section. The infrared communication section exchanges shared key data with a station that is another party of wireless data communication. The key data is required in identifying the station and encrypting data to be transmitted to the station. The CPU stores the shared key data into the memory. The key data is read from the memory. Using the key data, the encryption/decryption unit encrypts and decrypts data. The wireless communication section receives the data encrypted by the encryption/decryption unit and transmits it to external apparatuses. <IMAGE></p> |
