Current ninjas
Victor LOMNE
Co-founder & Security Expert
Victor holds a master degree in cryptology and computer security from the university of Bordeaux, France, and a PhD degree in microelectronics from the university of Montpellier, France.
He worked during 7 years as security expert in the hardware security team of the scientific division of ANSSI (French Cybersecurity Agency) in Paris, France. During these years he created and was responsible for the team lab, worked as penetration tester on a wide range of products, and was technical support for the ANSSI National Certification Center.
He then came back to work as researcher at the LIRMM (laboratory of computer science, robotics and microelectronics of the university of Montpellier), before co-founding NinjaLab.
Victor is also an active academic researcher in the fields of cryptology and hardware security, with publications, keynotes and program committee membership in top conferences like CHES, FDTC and COSADE.
Thomas ROCHE
Co-founder & Security Expert
Thomas holds an engineer degree in applied mathematics from ENSIMAG engineering school and a PhD degree in mathematics and computer science from the university of Grenoble, France.
He has been postdoctoral researcher at the university of Paris 8 and Oberthur Technologies (now IDEMIA).
Then he became security expert in the hardware security team of the scientific division of ANSSI (French Cybersecurity Agency) during four years, working on research in cryptology, penetration testing and certification. During these years, Thomas published numerous scientific papers in the leading conferences of this research field.
In 2015, Thomas joined APPLE where he worked in parallel in two different R&D teams located in Paris: the Fairplay (DRM) team and the ApplePay Security team. Continuing his work on physical security of cryptographic implementations inside the wide range of Apple products, Thomas also worked on the design and implementation of white-box cryptography for the Fairplay technology.
In 2017, Thomas left APPLE and co-founded NinjaLab with the ambition of analyzing and improving the security of cryptographic implementations, bounding together white-box and side-channel worlds.
