Dr. Nisha Verma, Vinay Rajan · International Journal of Cyber Threat Intelligence and Secure Networking · 2025
Cryptographic hash functions are fundamental to ensuring data integrity, authentication, and security in digital systems. This paper introduces and evaluates an extended 2080-bit variant of the Secure Hash Algorithm, designed to enhance resistance against collision, preimage, and length-extension attacks while maintaining computational efficiency. The proposed algorithm incorporates dynamic message expansion, multi-stage compression, and parallel processing techniques to optimize performance across diverse hardware architectures. Benchmarking results reveal that the 2080-bit variant outperforms conventional SHA families in both throughput and cryptographic strength, making it suitable for high-security applications such as blockchain, digital forensics, and secure communications. This study advances the development of robust, scalable hash functions for future-proof security systems.
