Hello, I am an Assistant Professor of Information Technology at the Indian Institute of Information Technology, Allahabad (IIIT-A), India. Earlier, I have also worked as a Visiting Scientist at the Advanced Computing & Microelectronics Unit of the Indian Statistical Institute, Kolkata (ISI-Kol), India, and as a Post-Doctoral Fellow at the National Institute of Technology, Rourkela (NIT-R), India. I have obtained my Ph.D. degree from the Dept. of Computer Science & Automation, Indian Institute of Science, Bangalore in 2015.
My research is basically involved in the field of Information and Communication Security. I have designed key management and authentication protocols for both self-organized and authority based Mobile Ad-hoc Networks (MANETs). Also, I have designed secure routing protocol for MANETs. Lightweight cryptographic algorithms which are cheaper to implement in resource constrained wireless communication devices is another area of my research. I have proposed a lightweight version of the pseudo-random number generation algorithm (PRGA) of the RC4 stream cipher, which has a negligible hardware implementation cost, yet secure enough for short-term wireless communications. Cyber physical system's security, specifically, security in Internet of Things (IoT) and Intelligent Transportation Systems (ITS) is the research domain where I have recently published couple of papers. The objective of my work in this filed is basically to apply the traditional and advanced cryptographic tools such as, proxy re-encryption, identity based cryptography (IBC), certificate-less cryptography (CL-PKC), to realize the special security needs of such networks. Application of anomaly based intrusion detection algorithms and protocols to detect attacks in different types of wireless networks is also included in my research interests.
