<p>In a method for authentication of wireless communication, one cell is selected from a carousel-type memory region (22) to generate an encryption key Ks in accordance with location information stored on the selected cell. First packet data having a message authentication code MACs and a random number Rs which are generated in a sensor terminal (2) is encrypted with the encryption key Ks to transmit the first packet data to an access point (30). When the access point (30) receives the first packet data from the sensor terminal (2), one cell is selected from a carousel-type memory region (12) within the access point (30) to generate an encryption key Kc in accordance with location information stored on the selected cell, and decryption of the first packet data is attempted in accordance with the encryption key Kc. In the event of failing in decryption, other cells are selected sequentially, and in the event of success in decryption, the message authentication code MACs is acquired to authenticate wireless communication in accordance with such a message authentication code MACs.</p> |
