The Advance of Digital Signature with Quantum Computing

Abstract

A digital transaction's sender or receiver's identity is verified using digital signature technology, a type of encryption. It allows users to prove their identity and the integrity of their message without relying on a third-party verification. Digital signatures are becoming increasingly important in the blockchain technology world. They enable users to verify the authenticity of digital assets, such as cryptocurrencies, and ensure that transactions remain secure. They also enable users to securely store their digital assets and prevent the unauthorized transfer of funds. Smart contracts, which are self-executing agreements that take effect when specific criteria are satisfied, also employ digital signatures. In addition, digital signatures are used to create digital signatures for digital documents, such as contracts, which allows users to securely sign documents without the need for a third-party verifier. This article presents the three primary digital signature algorithms presently utilized in blockchain technology: RSA, DSA, and ECDSA. It also discusses how quantum computers, which are currently being researched by some of the world's leading research companies, will affect traditional digital signature technology and what plans companies and countries have for this technology.
