proof of concept for 2p-ecdsa from HPS #69

Closed omershlo closed 4 years ago

Two-Party ECDSA from Hash Proof Systems and Efficient Instantiations (https://eprint.iacr.org/2019/503.pdf, Crypto19') is similar to Lindell17 but provides tight security and maybe performance improvement. It is required to implement the paper and evaluate it in comparison to Lindell17.
