An overview of quantum resistance digital signatures based on hash functions

Abstract

Facing the challenge of developing quantum computers, quantum-resistant digital signature algorithms have been developed based on hash functions and have received the attention of many scientists. This paper focuses on evaluating hash function-based quantum-resistant digital signature algorithms and their applicability in protecting transmitted information. Analyzing, synthesizing and comparing the strengths and limitations of the algorithms is the main research method of the paper. It also highlights the challenge of applying them in different fields such as banking, e-commerce, and government. The article is useful for those who are just starting to study quantum-resistant digital signatures, helping them get an overview of the field. It also assists regulators, governments and other organizations in making decisions and policies regarding digital signature security platforms.
