Who Am I About Me

Hi! I'm Abdel

I am currently a PhD researcher at CryptoExperts company and LIP6 laboratory in Paris, France. My field of research is the security and verification of cryptographic implementations in the random probing model against side-channel attacks.

What I Do Services

Cryptography Research

My thesis at CryptoExperts with LIP6 laboratory at Sorbonne University is focused on cryptography. Specifically, I am currently doing research on secure and verified cryptographic implementations against side-channel attacks in the random probing model.

Software Development

My three year bachelor degree in computer science have prepared me to be a part of any software development project. The next years of my career helped me concentrate my skills in the cryptography and cybersecurity domain.

Consulting

One of the main skills I am currently developing during my thesis at CryptoExperts is my ability to judge and review cryptographic implementations, specifications and protocols.

Projects

  • CRY.ME : a cryptography challenge about a secure messaging application

    CryptoExperts, Paris, France
    2022

    Lead developer and co-manager of CRY.ME, a secure messaging platform based on matrix protocol and embedding multiple cryptographic vulnerabilities for educational purposes. The product has been specified by ANSSI and developed by CryptoExperts for an "interCESTI" challenge dedicated to cryptography to evaluate the cryptographic skills of the concerned parties. The vulnerabilities tackle many topics in cryptography, including symmetric and asymmetric cryptography, pseudo-random number generators and messaging protocols.
