| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper proposes a firmware distribution method that provides incentives for distributors to help with distribu- tion to reduce the gas costs, using a smart contract and access control based on update records. The additional computations performed by IoT devices and distributor key management were reduced compared to those in previous studies by using access control instead of encryption. Further, the proposed approach was implemented and evaluated using a Raspberry Pi and laptop. The evaluation demonstrated that the gas cost per update was successfully lowered compared to the costs in previous studies. | |
