• A Ring Signature Scheme using Lattice-Based Accumulator ( M.Tech Project 3rd semester | Dr. Ratna Dutta, Dept. of Mathematics, IIT KGP| Jan 2021 - Apr 2021  )  

   – We addressed one ring signature scheme, its security criteria and how to apply it in different fields. The heart of the scheme was a Merkle Tree accumulator, with security from lattice-based hardness assumptions. We used C programming to implement the Merkle tree Accumulator.

• An Efficient Linkable Ring Signature Using A Pseudo Random Generator Aug 2020 - Nov 2020 (M.Tech Project 4th semester | Dr. Ratna Dutta, Dept. of Mathematics, IIT KGP)

     – This study discussed one linkable ring signature scheme, its security criteria and applications. We implemented a related cryptographic concept called Seed Tree with hash algorithms in C programming.

• Structural Reliability (M.Sc. Project | Dr. Raghu Nandan Giri, Dept. of Mathematics, Vidyasagar University | Jan 2018 - May 2018)

– This study demonstrates how to mathematically represent a real system and the structural reliability approach can be effectively applied to the physical model. The theory and algorithm are demonstrated by illustrative application to the monitoring of structural systems subject to fatigue deterioration.
