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, ~6 years of full time work experience (ongoing). I have written 3 Android Applications, 2 of which deal heavily / solely with Cryptography. One of the Apps requires NFC cards for authentication, and uses encryption for both data at rest and data in transit. 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. Notable projects completed include implementation of cryptography Algorithms for Standard Transfer Specification(STS), Design and Implementation of Android App and Backend for Medical Records Storage Service (this service stored all data encrypted in Databases), development for application for signing XML documents using XaDES standard, consulting for PCI-DSS compliance. 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.
