Biography

He received his Ph.D. in 1995 from the École nationale supérieure des télécommunications. Naccache's most notable work is in public-key cryptography, including the cryptanalysis of digital signature schemes. Together with Jacques Stern he designed the similarly named but very distinct Naccache-Stern cryptosystem and Naccache-Stern knapsack cryptosystem.

In 2004 David Naccache and Claire Whelan, then employed by Gemplus International, used image processing techniques to uncover redacted information from the declassified 6 August 2001 President's Daily Brief Bin Ladin Determined To Strike in US. They also demonstrated how the same process could be applied to other redacted documents.[1]

Naccache is also a visiting professor and researcher at the Information Security Group of Royal Holloway, University of London.[2]

In 2021, two epidemiologists denounced David Naccache to the management of the École normale supérieure. They accused him of having produced a fraudulent report in November 2018 for Genevrier Laboratories in exchange for a large payment (more than €250,000) in defence of a delisted drug, Chondrosulf.[3]

Awards

In 2020 Naccache was listed as a Fellow of the IACR, the International Association for Cryptologic Research, "for significant contributions to applied cryptography in industry and academia, and for the service to the IACR."
