Keyed/Unkeyed SHA-2

Abstract

Abstract In FIPS 180–2, NIST published SHA-2 as a new version of secure hash algorithm. SHA-2 offers four secure hash algorithms including SHA-1, SHA-256, SHA-384, and SHA-512. In other words, SHA-2 may have outputs 160, 256, 384, or 512 bits of message digest. However, SHA-2 algorithm uses fixed and predefined parameters in execution. It may be vulnerable to attacks. In this paper, we propose the Keyed/Unkeyed SHA-2 for security improvement.
