About Me

I am Dr. Arthur Sandor Voundi Koe, Assistant Professor at Xidian University, China.

Motivated by a passion for protecting information in our digital landscape, I delve into the fascinating world of security and privacy. My research explores cutting-edge solutions across three key domains:

1- Blockchain Security and Privacy: I delve into the intricate world of blockchain technology, leveraging applied cryptography to build robust defenses against vulnerabilities and safeguard the integrity of such revolutionary technology.

2- Cloud Computing Security and Privacy: I empower cloud users with functional encryption protocols (specifically Attribute-based encryption) ensuring they can leverage data's power while maintaining control and confidentiality.

3- Machine Learning: I am more of a Machine learning Enthusiast. I recall writing a survey paper on adversarial examples in Remote Sensing Imagery. I use machine learning to enhance vulnerability assessment in my solutions. I'm developing innovative methods that protect both users and data from malicious actors.

My working journey began with a postdoctoral experience at Guangzhou University, China, where I honed my skills and laid the foundation for my research endeavors. Today, I continue to push the boundaries of knowledge, collaborating with fellow researchers and contributing to a more secure and private digital world.

--Stay tuned-- to discover my latest research, engage in thought-provoking discussions, and explore the exciting world of security and privacy ! I'm working towards releasing some source code about published papers and recent ideas, on Github.
