Tasks & accountabilities

You will study of key distribution schemes based on identity. Identity-based cryptography (IBC) is in full extension because it eliminates the need for a KPI. There is an interest in its use for the distribution of symmetric cryptographic keys. An application example would be the protection of critical communications in 4G networks.

The internship will be composed of several phases:

·  Studying the state of the art of the distribution issues of symmetric cryptographic keys with identity-based cryptography,
·  Studying the state-of-the-art of various algorithms used in identity-based cryptography (encryption and signature), including the Boneh-Franklin and Sakai-Kasahara schemes,
·  Performing the benchmarks of scheme properties: resistance to ante-quantum and post-quantum attacks, complexity of their implementation, etc.
·  Studying the possible changes to manage several sizes of symmetric keys and proposing an example scheme

In addition to the theoretical study of schemes, you will also be required to implement algorithms to better understand their complexity.
In terms of resistance to attacks, a specific analysis will be carried out on the resistance to post-quantum attacks.

Required skills

You are in the second or final year of engineering school, a Master's degree or in the 4th or 5th year of university, specialising in Mathematics/Telecommunications, Networks.

You ideally have initial experience in Finance/Management Control acquired during previous internships or apprenticeship.

You have knowledge in:

·  Cryptography
·  Algorithms and complexity study,
·  Algebra, groups, finite fields, and elliptical curves,
·  Development tools in Python, C or C++. *

An interest in theoretical study would be a plus.

You are recognised for your meticulousness, independent way of working and reliability.

You are a good team player and you have excellent interpersonal skills.
