Analysis of a SHA-256 Variant [PDF]
Lecture Notes in Computer Science, 2006 SHA-256 is a cryptographic hash function which was proposed in 2000 as a new generation of SHA functions and was adopted as FIPS standard in 2002. In this paper we will consider a SHA-256 variant and a SHACAL-2 variant in which every arithmetic addition is replaced by XOR operation.
