Research interests

Where I want to contribute.

Post-quantum security

Post-quantum cryptography

I am especially interested in how rigorous mathematics becomes deployable security against quantum adversaries: lattice-based constructions, Learning With Errors, module-lattice schemes, and the reductions that connect hard problems to practical protocols. I want to study how these assumptions are analyzed, implemented, and stress-tested so future public-key systems remain trustworthy after large-scale quantum computers become realistic.

Number theory

Congruences, finite fields, modular arithmetic, and algebraic structure.

Code + proof

Readable experiments that test mathematical intuition.

Learn Math with Asim

Undergraduate math explanations in calculus, differential equations, and linear algebra.

Integer factorization

Modern public-key systems such as RSA rely on the practical difficulty of factoring large composite integers into their prime factors. These toy examples show the structure; real cryptographic moduli are vastly larger, which is why efficient factoring algorithms—and quantum threats to them—matter.
