A survey on digital signature schemes.

In the present era of extensive global connectivity, individuals continuously use E-Services across many domains. Consequently, the volume of sent data is increasing daily, giving rise to fresh challenges regarding safeguarding information. These challenges include integrity, authenticity, and non-repudiation of information sent between the sender and recipient. To achieve these security objectives, digital signatures are a viable solution. Where, it includes the original sender digitally signing secret data, which is verified by the intended receiver. This review paper investigates the current state of digital signature systems, thoroughly examining their theoretical basis, practical uses, and prospective technological developments. Furthermore, the examination digs into the challenges and algorithmic flaws. Finally, this comprehensive resource will assist academics, practitioners, and policymakers who are interested in cybersecurity and cryptography in obtaining current information on the Digital Signature Schemes infrastructure.
