So Siddharth Garg came up with a solution: Strategically divvy up the chip’s fabrication among many manufacturers. That way, nobody can know they’ve got the piece that hackers could take advantage of. Though the idea of breaking a chip’s manufacture into pieces already existed, Garg’s method does it using high-level math rather than doing it randomly, which guarantees a far greater level of security without spiking the cost of production. It also helps stem counterfeiting. Typically, chipmakers attempt to prevent rip-offs and foil corporate espionage simply by disguising crucial areas of the chip. But without a complete, intact chip to steal from, there’s no blueprint for a fake.
