NXP said publishing such critical information would bring substantial security risks to its clients by helping criminals break into security systems.

Rejecting its claims, the court ruled: The university has every right to publish its findings, and such a publication on the chip’s shortcomings will help in finding appropriate counter measures. Damage to NXP is not the result of the article but the production and sale of a chip with shortcomings.

Christophe Duverne, senior vice president at NXP, said: We opposed the publication to protect our customers. Publication of critical information is different from software hacks for which companies can issue a patch immediately. Disclosing things in detail including the algorithm will not benefit society, but potentially encourage criminals.
