Secure User Authentication Model Using Identity-Based Encryption (IBE) Scheme: Challenges, Techniques, and Trends

User authentication is the crucial component in ensuring that digital identities are securely authenticated when performing sensitive digital transactions. Building resilience against emerging cyber threats like identity theft and Man-in-the-Middle (MITM) attacks remains an ongoing challenge. Identity-Based Encryption (IBE) is a cryptographic method in the category of public key cryptography that allows the use of unique identifiers, such as email addresses, as public keys for encryption, making key management easier than traditional public key cryptography. This study presents a comprehensive overview of secure authentication techniques using IBE schemes proposed by researchers, emphasizing techniques that have been explored and introduced. The review examines current IBE schemes, including blockchain-based techniques, and analyzes the security features, application domains, implementation requirements, and challenges. By incorporating findings from previous works, this study identifies common challenges that impede real-world implementation and suggests a potential approach for combining alternative security methods to improve authentication robustness. The purpose of this work is to provide researchers and practitioners with a comprehensive review of secure authentication models, as well as practical insights to assist in developing an implementable authentication solution for real-world secure digital transactions.
