lrs

Implementation of linkable ring signatures using elliptic curve cryptography in Go. This prototype is research code and should not be used with sensitive data. It definitely has bugs!

Getting Started

Installing

To start using linkable ring signatures, install Go 1.14 or above and build:

$ go build

Run all tests

$ go test ./...

Create keys

Before starting you have to generate the signers public and private keys and a folder with public keys. Create key pairs:

$ lrs --gen

Sign a message

$ lrs --sign /path/to/pubkey/dir /path/to/privkey.priv message.txt

Check if signature is valid

$ lrs --verify /path/to/signature.sig

Check if signatures are created by the same private key

$ lrs --link /path/to/signature1.sig /path/to/signature2.sig

Benchmark 1000 public keys

$ lrs --benchmark 1000
Linked ring signature:
Total avg sign time was 0.771589(0.009996)
Total avg verify time was 0.765127(0.013479)
Simple ECC signature:
Total avg sign time was 0.0001766443(0.0001004724)
Total avg verify time was 0.0000000856(0.0000000311)
