The security of cryptographic hashes
Chad Teat, Svetlana Peltsverger · 2011
Password based or simple authentication is the most commonly used type of authentication. The decrease in resource costs and emergence of grid computing necessitates cryptologists and system architects reevaluate their chosen algorithm and password policies to address the rapidly weakening SHA1 and MD5. The major modern cryptographic hashing methods are easily computed with modern hardware and preimage attacks. Cloud computing and widely-available botnet-building tools have vastly increased the requisite password policy requirements to assure a secure cryptosystem. This paper provides an alternative password complexity schemes suitable for four distinct cryptosystem security levels.
