Abstract(in English) | Recently, many IoT devices have been used, and the number of IoT devices will increase in near future. In such era, it would be useful to control many IoT devices at once, and we propose a digital signature scheme with wildcards as a cryptographic primitive for doing it. In this paper, we define a formal model and security of the scheme, and propose a generic construction of it from identity-based encryption with wildcards. We also compare efficiency of possible instantiations obtained by the generic constructions. |
