He is also involved in projects related to cryptographic security and computational hardness of lattice problems. Aggarwal is a Principal Investigator in the Centre for Quantum Technologies at NUS and teaches courses such as Quantum Computing and Independent Introduction to CS Research.
Scholar-generated biography
Divesh Aggarwal is a researcher in Theoretical Computer Science, focusing on cryptographic protocols, lattice-based algorithms, and computational complexity. His work explores quantum attacks on cryptographic systems, such as Bitcoin, and develops methods to counteract them. Aggarwal has made significant contributions to solving problems like the Shortest Vector Problem (SVP) and Closest Vector Problem (CVP) using discrete Gaussian sampling and other advanced techniques. His research also includes non-malleable codes, leakage-resilient secret-sharing schemes, and reductions in computational complexity. These studies have implications for secure communication and cryptographic security in the face of quantum computing threats.
