Abstract(in English) | In recent years, cyber-attacks targeting Internet of things (IoT) terminals have been increasing. As a countermeasure, encryption methods such as public key cryptography are widely used. However, the increase in the number of IoT terminals has made it difficult to distribute and manage public keys. Therefore, a secret key sharing method in time-division duplex transmission systems using location and time-dependent channel state information (CSI) is attracting attention. On the other hand, we have proposed a chaos modulation scheme having channel coding effect and physical layer security based on common key cryptography. However, an advanced key sharing scheme was not considered in the previous studies. therefore, in this paper, we propose a secret key sharing method using CSI suitable for the chaos modulation. It is shown through numerical results that the proposed method achieves a key agreement rate close to 100% in high signal-to-noise ratio region, and that the coding gain is almost equivalent to that of the chaos modulation with perfect key sharing. |
