| Abstract(in English) | For smart security management of IoT systems, it is expected to utilize advanced cryptography such as identity-based encryption, broadcast encryption, searchable encryption, and aggregate signatures. Many of the practical advanced cryptosystems are based on the complex operation of pairing points on elliptic curves. One of the most promising pairings is the BLS12-381 curve, which is capable of achieving 128-bit security. Therefore, it is of great interest whether an advanced cryptographic protocol based on this pairing can be implemented in IoT end nodes with low resources. In this paper, we derive a method to implement the pairing with less than 4 Kbytes of RAM, and demonstrate that BLS signatures, one of the advanced cryptographic protocols, can be implemented on low-resource microcontrollers such as Arduino Nano Every, as long as the computation time is not too long. |
