'''Souradyuti Paul''' is an [[India]]n [[cryptologist]] (b. 1976). Formerly a member of [[COSIC]], he is currently working as an associate professor at [[Indian Institute of Technology Bhilai]]<ref>{{Cite web|url=https://www.iitgn.ac.in/faculty/comp/souradyuti.htm|title=Souradyuti Paul {{!}} IIT Gandhinagar|website=www.iitgn.ac.in|access-date=2018-12-12}}</ref> and a Guest Researcher for the [[National Institute of Standards and Technology]] in the United States. He participated in cryptanalysis of [[RC4]], [[Phelix#Helix|Helix]] and [[Py (cipher)|Py family of ciphers]] among others. He has co-designed the following ciphers<br />
<br />
* RC4A<br />
* [[Py (cipher)|RCR-32]], RCR-64.<br />
<br />
He also contributed to the design of a hash function iteration mode of operation [[Merkle–Damgård construction#Fast wide pipe construction|Fast-widepipe]].<ref name="NP10">Mridul Nandi and Souradyuti Paul.
