PhD on Symmetric Cryptography

**Job Description**
This PhD project focuses on the design and analysis of dedicated symmetric-key primitives that operate directly over prime fields and/or integer rings. The goal is to provide efficient cryptographic solutions for emerging applications of practical importance, including Format Preserving Encryption (FPE), Multi-Party Computation (MPC), Homomorphic Encryption (HE), and Zero-Knowledge (ZK). The work will involve a strong emphasis on understanding and proposing innovative security arguments for these novel primitives, rather than their implementation. The project is supported by the ERC Starting Grant “SYMPZON”.

**Skills & Abilities**
• Talented, motivated, enthusiastic, curiosity-driven researcher
• Deep analytical skills, initiative, creativity, and flexibility
• Strong interest in cryptography, especially symmetric cryptography and its real-world deployment
• Knowledge of at least one programming language (such as C, Sage, Matlab, Python)
• Good knowledge of algebra (including field and ring theories, and Gröbner basis) (a plus)
• Eager to work within a team and independently
• Excellent oral and writing skills in English

**Qualifications**
Required Degree(s) in:
• Cryptography
• Mathematics
• Computer science
• Engineering
• Related field (Master’s degree, or expect to obtain soon)

**Experience**
Other:
• Some experience with cryptography (if possible)
