Collaborative Cryptosystem Framework Enhancing Advanced Digital Signatures
Gahan A V, Geetha D. Devanagavi · 2024
Within the realm of networks lies a congregation of nodes, each with the central purpose of conveying information from one endpoint to another. Ensuring the security of this information against unauthorized access is a pivotal concern. The concept of cryptography emerged as a response to the imperative of safeguarding crucial data exchanged across vulnerable networks. Encryption, a central facet of cryptography, involves encoding information using a confidential key, thereby enabling only the intended recipient to decipher it. In contrast, cryptanalysis pertains to the unauthorized extraction of information without knowledge of the secret key. The primary challenge encountered in signature-based approaches is the computational burden arising from the utilization of substantial real numbers essential for both the signature and verification processes. This paper introduces an efficient and compact digital signature algorithm with reduced complexity, aimed at ensuring robust secure communication. Proposed a simplified operations to facilitate the signature and verification procedures, akin to how individuals sign legal documents and subsequently authenticate them in the presence of witnesses. The study delves into key generation, signature creation, and verification processes inherent to diverse digital signature methodologies.
