| Abstract(in English) | Key agreement schemes using noise on the channel have been studied theoretically. Since these schemes require only an error correction circuit, they are suitable to share a key between small devices such as RFID tags. However, there are two practical problems. The first problem is that it is difficult to code information according to channel capacity. The second problem is that the size of a key is small if noise of a receiver strongly correlates with that of an eavesdropper. To solve the problems, we propose two methods. The first method is that a sender intentionally adds noise to signals. The second method is that after a receiver permutes received signals the receiver resends permuted signals to the sender. These methods enable us to share the large-size key by practical BCH codes. Specifically, simulation results show that a 50-bit key per 127-bit transmitted data can be shared using the (127, 120) BCH codes. |
