Research
My research interests are around cryptologic problems with a focus on post-quantum cryptography, i.e. quantum-resistant cryptography.
- Actually, I deal with lattice theory for cryptography: as an example, I helped build an Ideal Lattice Challenge.
Last papers on this themathic:
- RNS Arithmetic Approach in Lattice-based Cryptography - Accelerating the "Rounding-off" Core Procedure: paper.pdf.
- LLL for Ideal Lattices: Re-evaluation of the Security of Gentry-Halevi's FHE Scheme: paper.pdf.
- Fully Homomorphic Encryption using Hidden Ideal Lattice: paper.pdf.
- Since my Ph.D., I also worked on modular arithmetic and number system with a focus on building efficient and side-channel resistant cryptosystems
Last papers on those themathics:
- Efficient Modular Exponentiation Based on Multiple Multiplications by a Common Operand: paper.pdf.
- Selected RNS Bases for Modular Multiplication: paper.pdf.
- Efficient modular arithmetic in Adapted Modular Number System using Lagrange representation: paper.pdf.
