Raghavendra N Vernekar

Research Scholar · Computer Science and Automation, Indian Institute of Science, Bengaluru

I am a research scholar at the Department of Computer Science and Automation, Indian Institute of Science, Bengaluru, working under Dr. Arpita Patra in the CrIS Lab.

I completed my Master’s at IIT Madras, where I worked with Dr. Shweta Agrawal in the Department of Computer Science and Engineering. My M.S. thesis was titled Multi-key Homomorphic Encryption and Secret Sharing. Before that I read Computer Science for my undergraduate degree at NIT Goa.

I am interested in learning about new cryptographic primitives and applying them to real-world problems. Away from the desk I play cricket, table tennis and badminton, and spend time on music and photography.

Randomized Encoding

Suppose Raghavendra wants Pratik to compute a function $f(x)$ on his secret input $x$. The obvious naive method could be to send $x$ to Pratik who can then compute $f(x)$. What Raghavendra really wants is something slightly strange: Pratik should learn the result of the computation without necessarily learning the input to the computation. ...

Diffie–Hellman and What It Actually Assumes

Everyone learns Diffie–Hellman as a party trick with paint colours. The trick is fine. What it hides is that the security of the protocol does not rest on the discrete logarithm problem, and the gap between the two matters in practice. ...
