“We have long been able to protect data at rest and in-transit with end-to-end encryption. But running code on that data required decryption — slicing open a gaping security hole that meant personal data was manipulatable by the third party that controlled the code. Confidential computing protects data in use for the first time by cordoning off a black box within the CPU that decrypts, computes on, and re-encrypts data so privately that not even the local operating system knows what’s happening. This is confidential computing.”
