Many classical cryptosystems today rely on the computational hardness of mathematical problems like integer factorization or discrete log problem to ensure their security. The recent advancement of quantum computing has challenged the security of these cryptosystems. This has renewed interest in designing cryptosystems that can withstand quantum attacks and remain secure in the post-quantum world. 

​

My research primarily focuses on isogeny-based cryptography, a fairly young and promising post-quantum cryptography with sophisticated algebraic structures and unique security properties. Isogeny-based protocols are particularly appealing for very small keys compared to other post-quantum cryptography candidates, saving on bandwidth and storage. I aim at making a significant advancement to the field of isogeny-based cryptography by developing novel protocols and analyzing the security of our scheme in the post-quantum era. I have already designed protocols like key-oblivious encryption, signcryption, identity-based signatures, deterministic wallets, puncturable signatures and group key exchange protocols based on isogenies.  I am hoping to explore the other primitives in the isogeny world in the near future.
