As part of an independent security evaluation laboratory, i worked on two main topics : hardware security evaluation and pay-Tv security.I continued to develop hardware reverse engineering tools and techniques involving failure analysis equipments and home made softwares.

Two complementary tasks:- security evaluations and risk analysis- process and tools developmentTherefore, i worked on topics such as failure analysis, optics, electronics, computer sciences as well as security and attacks.It is hard to list all developments and tests that have been performed during these three years because the team was lead by innovation and challenges.

A short list would include :* Laser attacks- depackaging - repackaging + bulk thinning process development.- structure localization by pass - fail tests- fault injections- pass - fail imagery of the chip (tool development and usage)* FIB EDIT- shield analysis (local and global bypass...)- other edit for bus probing, security feature bypass...* Micro-probing*Miscellaneous:- development of an imagery software for GPixels optical / SEM images- development of photolithography tool (system setup, control software creation, process definition and first tests)- creation of a OBIC imagery software for Zeiss LSM- Capacitive scanning using AFM- electrical glitch tests...
