PCT No. PCT/JP97/02303 Sec. 371 Date Mar. 26, 1998 Sec. 102(e) Date Mar. 26, 1998 PCT Filed Jul. 3, 1997 PCT Pub. No. WO98/01975 PCT Pub. Date Jan. 15, 1998Wireless communication method and apparatus which can perform the wireless transmission/reception of encrypted data without previous provision of a cryptographic key and without any system for registering a cryptographic key. Under control of a communication control section 504 in PC 1, the PC 1 transmits its own identification information to a printer 2 and receives identification information of the printer 2. The PC 1 has an encrypting/decrypting section 502 which generates a cryptographic key by using the identification information of the printer 2 and its own secret algorithm read out of an identification information storage section 510. According to a cryptographic program using such a cryptographic key, data is encrypted and transmitted toward the printer 2.
