Nvidia has reiterated that its chips do not have back doors or kill switches, days after being summoned by Chinese authorities over alleged security issues.

“There are no back doors in Nvidia chips. No kill switches. No spyware,” the semiconductor design giant said in a lengthy blog post late on Aug. 5. “That’s not how trustworthy systems are built—and never will be.”
