| Abstract(in English) | In recent years, with the proliferation of IoT devices and computer performance improvement, there are increasing expectations for advanced cryptography to cope with complex network security issues. The BLS signature, based on bilinear and non-degenerate pairing mappings, and its extension, the aggregate signature, are the examples. There are various types of elliptic curves and pairings based on them, which differ in computational cost and security against attacks. In this paper, we propose an implementation of pairing on Cocks-Pinch curves of embedding degree 6, for which new parameters were investigated in 2019. In particular, we show how to compute the final exponentiation efficiently on a PC with x64 architecture and evaluate the implementation performance. We also discuss the challenges for faster implementation. |
