Oblivious RAM aims at allowing remote access to data without giving away even the access patterns of the data to the server. The objective of this work was to explore the various algorithms for O-RAM and try and improve the current known complexities.
Max Planck Intitute for Software Systems, Saarbrücken (May 2011 - July 2011)
Mentors: Michael Backes and Aniket Kate
I devised a new AVSS protocol with a communication complexity of O(kn^2), improving the known best complexity of O(kn^3), where n is the number of parties participating in the secret sharing scheme and k is the security parameter.
Shriram Insight Share Brokers Ltd., Kolkata (May 2009 - July 2009)
