fbreuer2 / u2f-ether

A reimplementation of https://github.com/Higgsboson-X/u2f-ethereum

Introduction

This is an implementation of the server-side part of the U2F protocol on the Ethereum blockchain.

No hardware key is needed to test the implementation since a software token is used for testing purposes.

The SmartContract implements U2F with curve SECP256R (standard) and with curve SECP256K (non-standard). This decision was made because the verification of signatures generated on curve SECP256K in Ethereum is a lot cheaper than verification of signatures on curve SECP256R. A user has the option to select which curve should be used for verification, since the user has to carry the cost of it.

Current benchmark:

Action	SECP256K (non-standard)	SECP256R (standard)	Factor (SECP256R/SECP256K)
Registration	316919	1706232	5,38
Create transaction	99115	99115	1
Verify transaction	176090	1522286	8,6
