Hello, I’m Ji Yong-Hyeon.

I am passionate about mathematics, cryptography, and the engineering of secure systems. My academic and technical interests center on the design, analysis, and implementation of cryptographic algorithms, with an emphasis on connecting rigorous theory to practical applications.

I am particularly interested in:

• Cryptographic system design
• Algorithm implementation and validation
• Mathematical foundations of modern cryptography
• Security engineering for real-world environments

My goal is to contribute to both the theoretical and applied sides of cryptography by building reliable, efficient, and well-analyzed solutions. Through continuous study, experimentation, and project work, I aim to deepen my expertise and produce work that is both technically sound and practically meaningful.

If you are interested in cryptography, mathematics, or research collaboration, feel free to connect.

• Cryptographic Algorithm Implementation
  Practical implementation of cryptographic algorithms with attention to correctness, efficiency, and security.

• Algorithm Analysis and Validation
  Evaluation and verification of cryptographic primitives and protocols against correctness and security requirements.

• Optimization for Constrained Environments
  Development of cryptographic solutions for systems with limited computational or memory resources.

• Mathematical Problem Solving
  Strong mathematical background supporting rigorous analysis, design, and research in cryptography.

I am continuously working on projects related to cryptography, security engineering, and mathematical computing.
