Securing computation and data — from the silicon of a smart card to the distributed control plane of a software-defined network, and into the post-quantum era.
Research Focus
A cohesive programme in applied cryptography and information security, with strong threads in hardware security, networks and emerging cryptographic paradigms.
Lightweight image encryption using cellular automata and chaotic maps (Logistic, Tinkerbell, Hénon) for resource-constrained IoT devices.
Differential / higher-order power analysis on smart cards, and countermeasures via blinding, randomized exponents and secure modular exponentiation.
Post-doctoral research at IIT Bhilai; forensic investigation models for QR-code and Android-app based identity fraud.
Secure, resilient distributed control planes, TCP-SYN flood detection, and compromised-switch detection in software-defined networks.
Public data auditing with stub-, ZSS- and signature-based verification for storage-level integrity in cloud resource pools.
Quantum-resistance for classical cryptographic keys, QKD protocol study, neural cryptography and McEliece-based blockchain security.
