Extended DSA
Chen‐Yu Lee, Wei-Shen Lai · Journal of Discrete Mathematical Sciences and Cryptography · 2008
In this article, we propose an extended version of DSA (Digital Signature Algorithm), namely DSA-2. It offers the four types of secure hash algorithms in SHA-2. We extend the DSA such that the output sizes are variable from 160, 256, 384, and 512 bits.
