Hi, I'm Suprava Roy, a Prime Minister's Research Fellow at the Department of Mathematics, IIT Kharagpur. My research interests are in the area of cryptography and network security.  I have been carrying out my research in this field under the supervision of Prof. Ratna Dutta, IIT Kharagpur. My research focuses mainly on post-quantum cryptography, notably functional encryption, fully homomorphic encryption and related cryptographic primitives for preserving privacy in the cloud assisted environment.
