Somnath Panja

Postdoctoral Associate

University of Calgary

I am a Postdoctoral Associate under the supervision of Professor Reyhaneh Safavi-Naini in the Department of Computer Science, at the University of Calgary. I am doing research on Quantum Key Distribution, Information-theoretic security, Blockchain and Cryptography and Security. I completed my PhD degree in Computer Science from Indian Statistical Institute, India, in 2021. Prior to joining the PhD program, I had been working for 6 years and 4 months at Alumnus Software Limited, India. I completed the M.Tech degree from Indian Statistical Institute, India, in 2010, the M.Sc. degree in Mathematics from Indian Institute of Technology Madras in 2008, and the B.Sc. degree in Mathematics from Ramakrishna Mission Residential College, India, in 2006.

Talk Description

Quantum-enabled Hybrid Encryption

Secure communication today relies on the hardness of computational problems. Shor’s algorithm efficiently solves all computational problems that are used in today’s secure communication. Quantum key distribution (QKD) establishes a secure shared key between two parties, and uses the key in a One-Time-Pad (OTP) encryption system, achieving information theoretic security. This however cannot support high-speed (Gbit/sec) communication. We propose Quantum-enabled Hybrid Encryption (QHE) that uses quantum communication to generate a pair of correlated strings for two parties, and use them in KEM/DEM paradigm (Key Encapsulation Mechanism/Data Encapsulation Mechanism) of hybrid encryption to achieve post-quantum security. QHE has proven security, uses AES algorithm that allows very high encryption rate, and does not have any known quantum attack. QHE is an exciting approach to securing high speed communication for settings that allow quantum communication (e.g. earth to space).
