Deepanshu Rana · International Journal for Research in Applied Science and Engineering Technology · 2024
Abstract: Digital signatures have emerged as crucial cryptographic tools for ensuring the authenticity, integrity, and nonrepudiation of electronic documents and transactions in the digital age. With the increasing reliance on electronic communication and the growing threat landscape, itis essential to have a thorough understanding of digital signature algorithms and their suitability for various security applications. This review paper provides a comprehensive analysis of digital signature algorithms, including RSA-based, elliptic curve-based, and post-quantum cryptographic algorithms. It explores the underlying principles, security features, and performance characteristics of each algorithm category. The paper discusses the security requirements that digital signatures aim to fulfill and examines the strengths, limitations, and real-world applications of RSAbased, elliptic curve- based, and post-quantum cryptographic algorithms. It presents a comparative evaluation of these algorithms, considering security factors, performance metrics, and suitability for different use cases. The paper also addresses recent developments in quantum-safe cryptography, standardization efforts, and emerging digital signature algorithms. Overall, it provides valuable insights for practitioners and researchers in the fieldof digital signatures and cryptography.
