| Outline of Annual Research Achievements |
To incentivize the incumbent to share the spectrum in efficient and profitable ways, auction based mechanisms are extensively discussed. Based on our research results on last two years, we propose an efficient privacy preserving spectrum sharing framework for IoT system by utilizing ElGamal cyptosystem. The proposed scheme hides the user’s bid from both the auctioneer and other users. By extensive evaluation results, we show that the proposed framework could achieve good spectrum utilization efficiency and user satisfactory ratio, at the cost of acceptable communication and computation overheads.

| Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
We consider that the research progresses smoothly. We have published 2 journal papers, 2 internal conference papers and multiple domestic
conference papers in 2019 under the support of this funding.
|
| Strategy for Future Research Activity |
In the following year, we will consider the problems with sophisticated and practical models. Meanwhile, we will perform the experiments by realizing the proposed scheme in testbeds.

| Causes of Carryover |
コロナウィルス感染防止のため、多数の学会が中止するため、残額が生じてしまう。残りの助成金は２０２０年度の国内学会の参加費として使用する予定である。
