I am a reseacher, currently based in Washington, D.C. I am working as a Foreign Guest Researcher at NIST (National Institute of Standards and Technology) in the Computer Security Division. My primary area of research is Cryptography and Artificial Intelligence.
Cryptography: My research focus is on cryptographic algorithms and security analysis. Currently, I am working on theoretical and practical aspects of authenticated encryption schemes (or AEAD) in the lightweight category.
Lynx: family of lightweight authenticated encryption schemes based on a tweakable blockcipher. It provides birthday bound security for integrity security in both nonce respecting as well as nonce misuse and RUP scenarios, as well as birthday bound security for privacy in nonce respecting scenario.
I have also worked extensively in biometric cryptosystem, and implemented several Iris Recognition Systems for extremely low power and resource constraint devices.
AI: I am working in the NIST Automated Vehicle Program, for autonomous driving in the Automated Vehicle AI Team under Strategic and Emerging Research Initiatives (SERI). Research focus is probabilistic ML, uncertainty estimation for various computer vision tasks like classification and detection.
Previously: I have worked on several NLP tasks and meta-learning techniques involving LLMs.
In the past, I have worked with various firms like ETRI, Irisys, Merlot lab, Seoho electric , DXC Technology (formerly Computer Sciences Corporation) etc. on several projects and research topics in the field of cryptography, AI and related areas. I am the creater of SSE-DB[sunset], which is a restricted relational database based on searchable symmmetric encryption. Written a quantum simulator, some quantum algorithms can be tried at this link.
