I have MS in Information Security with research interest of Cryptography. I have implemented Cryptography algorithms in Java and C, written security solutions in J2EE and Java, have implemented datastructures in Java, and built two websites for research / proof-of-concept purposes. Additionally, ~2 years of IT experience. I have taken Graduate level courses in Cryptography and Security that dealt with analysis of Cryptographic protocols, my Masters level project involved design of a Cryptographic protocol for a specific authentication problem in three-party settings. I have executed a number of projects that focussed almost entirely / heavily on Cryptography. I have also written Cryptographically signed Java applet for a J2EE application. Details about projects executed available on request. You might want to go through reviews project creators left for me on freelancer.com, see https://www.freelancer.com/u/ciphe.html.
