I am a researcher with expertise in cryptography and TLS (Transport Layer Security). I have hands-on experience working with cryptographic modules(CMVP, KCMVP) and TLS implementations across both power infrastructure and automotive industry sectors. Currently, I am focusing on Post-Quantum Cryptography (PQC) optimization and migration strategies as organizations prepare for the quantum computing era. My research interests center on performance optimization of PQC algorithms, particularly lattice-based schemes, and developing practical migration frameworks for transitioning from classical to post-quantum cryptographic systems. Additionally, I am actively exploring the intersection of PQC and AI, investigating how artificial intelligence can enhance post-quantum cryptographic implementations and security analysis.
