31.3 μs/Signature-Generation 256-bit 𝔽p ECDSA Cryptoprocessor
Shotaro Sugiyama, Hiromitsu Awano, Makoto Ikeda · 2018
A 256-bit Fpelliptic curve digital signature algorithm (ECDSA) cryptoprocessor featuring low latency, low energy consumption, and the ability to change the elliptic curve parameters is designed and fabricated in a 65-nm silicon on thin buried oxide (SOTB) CMOS process. We have demonstrated the lowest ever reported signature-generation time of 31.3 μs. Energy consumption is 3.28 μJ/signature-generation, which is same as the lowest reported to date.
