Job Description
Thesis Subject
Symmetric key primitives are crucial to protect confidentiality and integrity in everyday life.
If there exist some well-established ciphers like the Advanced Encryption Standard, some specific contexts (think about resource-constrained IoT devices for instance) create the need for new ciphers with specific attributes. Evaluating the security of both these types is primordial: we must ensure the ciphers in use are resistant to state-of-the-art attack techniques to confidently continue using it, while before adopting a new cipher we must check its resistance to well-known attack vectors, but also ascertain their specific attributes do not introduce new types of security flaws.
Evaluating the resistance of symmetric key primitives to mathematical attacks is what is referred to as cryptanalysis. It is the central focus of this thesis.
This PhD project will be dedicated to the study of structural and statistical cryptanalysis techniques, with a stress on techniques exploring the evolution of relations between
quartets of messages through encryption.

This PhD project will be carried out in the CARAMBA team at Loria, in Nancy.
