| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Server-aided computation is the method which delegates computation to server side to execute heavy computation like a digital signature on the device which has low computational resource. In this paper, we propose a delegation protocol which can compute scalar multiplication efficiently without exposing the secret information and can verify computational result. We also evaluate performance of the proposed protocol from the viewpoint of computational complexity of the small device side and tolerance to the cheat of the server side. |
