FPGA implementation of ECDSA for Blockchain

2019 IEEE International Conference on Consumer Electronics - Taiwan (ICCE-TW), 2019
In this paper, we address Field Programmable Gate Array (FPGA) implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA), which is suitable for cryptocurrencies in blockchain. Although the ECDSA requires high computational efforts, utilization of a specific logic circuit allows us quick and easy computation.

The Security of DSA and ECDSA [PDF]

, 2002
DSA and ECDSA are well established standards for digital signature based on the discrete logarithmp roblem. In this paper we survey known properties, certification issues regarding the public parameters, and security proofs.ECDSA also includes a standard certification scheme for elliptic curve which is assumed to guarantee that the elliptic curve was ...
