Abstract

Blockchain is a distributed, decentralized ledger mechanism with a various features. It is used in diverse applications nowadays, from financial sector to password management. It does not have any central tool to validate and verify the transactions, yet every transaction in the Blockchain is secured and verified. This is achieved because of a consensus algorithm in the network. Latest study reports show that emergence of quantum computing will impact the overall safety of Blockchain and its internal working. Attacks using Grover's and Shor's algorithm can threaten the hashing and public key schemes in cryptography. It will force a complete redesign of the Blockchain systems to withstand quantum attacks. So there is a need to develop quantum-safe Blockchain systems. Consensus mechanisms like Proof of Work (PoW) and Signing algorithms like Elliptic Curve Cryptography used in Blockchain can be modified to overcome quantum attacks. Here a comparative study and analysis of different consensus algorithms developed using post-quantum cryptosystems are done, which can be implemented in Blockchain systems to make them quantum safe.

基于后量子密码系统的区块链共识算法研究

区块链是一种分布式、去中心化的分类账机制，具有多种功能。如今，它被用于从金融部门到密码管理的各种应用中。它没有任何中央工具来验证和验证事务，但是区块链中的每个事务都是安全的并经过验证的。这是由于网络中的共识算法实现的。最新研究报告显示，量子计算的出现将影响b区块链的整体安全及其内部工作。利用Grover算法和Shor算法的攻击会威胁到密码学中的散列和公钥方案。这将迫使区块链系统进行彻底的重新设计，以抵御量子攻击。因此，有必要开发量子安全的区块链系统。像工作量证明(PoW)这样的共识机制和区块链中使用的椭圆曲线加密等签名算法可以被修改以克服量子攻击。本文对使用后量子密码系统开发的不同共识算法进行了比较研究和分析，这些算法可以在区块链系统中实现，使其具有量子安全性。
