| Outline of Final Research Achievements |
To construct networks securely and efficiently for IoT devices, we proposed several digital signature schemes with low costs. In particular, for ID-based signatures which allow any user to utilize its own ID information or MAC address as a public key, we proposed more secure scheme even for a shorter key length and a key-updatable scheme if a secret key is revealed. Next, we proposed a security analysis method for networks with digital signatures. We also conducted experiments the above results on Raspberry-Pi to confirm the performance. We published these results as seven academic articles and seven international conference proceedings.
