Bitcoin makes use of two hashing functions, SHA-256 and RIPEMD-160 , but it also uses Elliptic Curve DSA on the curve secp256k1 to perform signatures. The C++ implementation uses a local copy of the Crypto++ library for mining, and OpenSSL for normal usage. The field of the elliptic curve is not over the field of real numbers. It's over a finite field modulo some prime. For Secp256k1 the prime p = 2^256 - 2^32 - 2^9 - 2^8 - 2^7 - 2^6 - 2^4 - 1. In this work, we mount a lattice attack on the ECDSA signatures implemented by the latest version of OpenSSL which uses the windowed non-adjacent form method to implement the scalar multiplication. We first develop a new way of extracting information from the side-channel results of the ECDSA signatures. Just given a small fraction of the information about a side-channel result denoted as (November11, 2017; 33 days ago(2017-11-11)) Bitcoin Core is the reference client of bitcoin . Initially, the software was published by Satoshi Nakamoto under the name Bitcoin, and later renamed to Bitcoin Core to distinguish it from the network . [1] For this reason, it is also known as the Satoshi client. [2] It is t ECDSA is a signature algorithm that can be used to sign a piece of data in such a way, that any change to the data would cause signature validation to fail, yet an attacker would not be able to correctly re-sign data after such a change. It is a variation of DSA (Digital Signature Algorithm). ECDSA stands for Elliptic Curve Digital Signature
