Welcome to the homepage of Ma Yijia!

I am currently a 3^rd-year undergraduate in the ACM Honors Class at Shanghai Jiao Tong University, majoring in Computer Science.

My research interests lie in computer security, with a particular focus on secure decentralized systems. I am broadly interested in the architectures, protocols, and cryptographic foundations that ensure confidentiality and integrity. I am currently exploring methods for achieving privacy and integrity, including Trusted Execution Environments (TEEs), cryptographic techniques, oblivious data structures, and I am also interested in identifying and analyzing potential vulnerabilities and exploitations in such systems.

I have a strong academic background in these areas and have received awards in CTF competitions. Under the supervision of Prof. Guoxing Chen at SJTU, I have been conducting research on TEEs and Oblivious RAMs. We seek to optimize the performance of these secure architectures. At present, we are developing a framework to accelerate the loading and attestation of memory-intensive programs in the enclave, providing a smoother startup performance.

I am seeking a research internship opportunity for Summer and Fall 2026. In the future, I plan to pursue a Ph.D. in Computer Science, beginning in Fall 2027.

This site is under active construction, and will be moved from GitHub Pages to a VPS in the near future.
