A Secure and Lightweight Cryptographic Framework for Smartphone Authentication and Password Recovery Via Secret Sharing

Secure authentication and dependable password recovery are imperative as smartphones store utterly sensitive personal and financial data. The recovery methods offered by traditional password-based systems are limited and vague in cases of authorised users losing their devices or failing to remember their credentials. In this study, a cryptography-based framework for password recovery and authentication is proposed to provide safe and private access restoration. It integrates lightweight cryptographic primitives, multi-factor authentication and recovery based on secret sharing. The scheme we suggest distributes the recovery secrets among several trusted entities in various shares, such that no single entity can compromise the system. The low computational and communication overhead of the framework permits it to endure popular assaults including brute-force, replay, impersonation and man-in-the-middle attacks. This research aims to create a safe and effective solution for next-generation mobile authentication systems.
