During Ph.D., Arijit built some cryptographic techniques with Prof. G.P. Biswas (supervisor). He searches the practicability of the schemes that he has proposed so far. In addition, he is interested to find out some real-time security issues and their counter measurements for our modern digital society.  During his tenure of Post-Doctoral research,  Arijit worked and published a couple of research articles with Prof. Chun-I Fan (supervisor). Besides, he aims to build real applications based on modern cryptographic techniques.

The research work of Arijit comprises some new cryptographic directions, such as ID-Based Cryptosystem, Certificateless Cryptosystem, and Attribute-Based Encryption. Arijit designed some encryption, signature, and signcryption schemes based on the aforementioned concepts. His thoughts are always toward the betterment of society to provide essential CIA property along with the authenticity of sensitive data. Besides the scheme construction, Arijit does formal security analysis under the standard model (SM) and measures the efficiency through ideal simulation, e.g., Arduino, and R-Pi, with cryptographic libraries, such as PBC, JPBC, and MIRACL. He was awarded the Ph.D. degree, thesis entitled Design of some Identity- and Attribute-Based Public Key Cryptosystems in February 2018. Although Arijit did some security analyses based on the ROM, he believes the best practice would be the avoidance of ROM during security assessment.

So far in the research career,  Arijit got the privilege of working with some eminent researchers in the field of security and communication,  Prof. G.P. Biswas, Prof. Chun-I Fan, Prof. Sajal K Das,  Dr. Ruei-Hau Hsu, Prof. Daniel Benevides da Costa, Dr. Walid Saad, Prof. Md Zakirul Alam Bhuiyan, Dr. Debasis Das, Dr. SK Hafizul Islam,  Dr. Ruhul Amin, Prof. Kim-Kwang Raymond Choo,  Dr. P. Vijayakumar,  Prof. Muhammad Khurram Khan, Dr. Trupil Limbasiya, and Dr. Debasis Giri. 

His research interests include applied cryptography,  information security,  edge security,  automotive security,  and decentralized data privacy.
