| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Searchable encryption is one of the advanced cryptographic primitives, which is being studied and developed actively due to the feature of being the nearest to practical use. We focused on the point of updating client keys of a searchable encryption and showed an abstract model, in Matsuzaki et al. SCIS2017. In this paper, we further show a detailed model as well as the requirements for desirable functionalities. Then we propose a concrete construction that meets the requirements and that fits to our model. First we modify the scheme of proxy re-encryption with keyword search of Shao et al. 2010, which possesses the bidirectionality, so that it attains the unidirectionality,and we apply it into our model. |
