EVOLUTION AND ANALYSIS OF SECURED HASH ALGORITHM (SHA) FAMILY

With the rapid advancement of technologies and proliferation intelligent devices, connecting to internet challenges have grown manifold, such as ensuring communication security keeping user credentials secret. Data integrity privacy become crucial concerns in any ecosystem advanced interconnected communications. Cryptographic hash functions been extensively employed ensure data insecure environments. Hash are also combined with digital signatures offer identity verification mechanisms non-repudiation services. The federal organization National Institute Standards Technology (NIST) established SHA provide optimal performance over some time. most well-known hashing standards SHA-1, SHA-2, SHA-3. This paper discusses background hashing, followed by elaborating on evolution family. main goal is present a comparative analysis these focus their strength, limitations against common attacks. complete assessment was carried out using statistical analysis, extensive fault defined test environment. study outcome showcases issues SHA-1 besides exploring benefits all dominant variants SHA-2 concludes that SHA-3 best option mitigate novice intruders while allowing better cost-effectively.
