Cryptography is the science of secure computation and communication. The scope of cryptosystems, nowadays, ranges from private-key encryption and authentication to more complex systems such as publickey encryption, electronic voting, secure multi-party computation on large data sets, etc. My specialization is in foundations of cryptography, a field that aims at designing cryptographic protocols with provable security, and computational complexity theory which provides the framework for such studies. My research has significantly improved our understanding of the assumptions behind the way modern cryptosystems are modeled and proved to be secure. Cryptographic assumptions exist in two forms:
