Abstract

The Secure Hash Algorithm is one of the most commonly used hashing
algorithms on the time being. Experts are proposing for much secured
SHA-1 because of some reports and study conducted on SHA-1 collision
attacks. The aim of the enhanced Secure Hash Algorithm-1 (SHA-1) is to
strengthen its original version that is expected to resist possible SHA-1
collision attacks. The enhanced SHA-1 had integrated the following
modification: 1) Enhancement on the pre-processing, specifically on the
parsing method. 2) The message digest and the final message digest
formula was enhanced by giving additional shifting, xoring and improved
mathematical formula. The enhanced SHA-1 maintains its original rounds
which consist of 80 rounds and message digest output of 160 bit. Based
from the result, the enhanced algorithm specifically on mathematical
calculation of parsing method and message digest had shown great effects
on its result on the hash value despite of a very minimal time delay, the
enhanced algorithm is better and more secure.

The authors made some revision to its original function and observed that
SHA-192 to be better than the existing SHA-1 hashing algorithm in terms
of number of brute force attack but in terms of time performance of the
algorithm the proposed SHA-192 has a time delay since it needs to
generate a 192 bit of message digest [2]. A digital signature consists of
a mathematical calculation that demonstrates the authenticity of a
message. Dr. Herong Yang [4] discussed the use of hash algorithm in a
digital scheme for email messages.
