Zero-knowledge proof-based cryptographic authentication methods

Abstract

The article “Authentication Methods Based on Zero-Knowledge Cryptography” examines the evolution of authentication methods in a context where security and privacy are increasingly crucial. It highlights the need for systems that ensure the confidentiality and integrity of information, especially in an increasingly vulnerable digital environment. The estudy focuses on exploring various categories of authentication, from traditional methods such as passwords and physical tokens to more advanced approaches like Multi-Factor Authentication (MFA) and the use of digital certificates. However, the main focus is on the analysis of Zero-Knowledge Proofs (ZKP) as an innovative solution to mitigate the inherent vulnerabilities of traditional methods. The methodology used includes an exhaustive literature review and a detailed analysis of ZKP protocols applied to authentication, with particular emphasis on their implementation in cloud computing environments. The results underscore the effectiveness of ZKPs in verifying user identities without compromising sensitive information, presenting significant advantages over other methods.
