Chip firm Intel and Arqit Quantum, which specialises in quantum-safe encryption, have launched a security solution in which even they “are outside the trust boundary.”
The solution uses Intel Trust Domain Extensions (Intel TDX) and Arqit NetworkSecure, and beefs up the security of Arqit’s quantum-resistant crypto key delivery system. The release uses the term confidential computing to describe the result, which can “elevate security to the next level”, we’re told.
The data protection is supposed to help ensure no third party, not even the cloud provider, can access a customer’s encryption keys or workloads, even when distributed across multiple hosts.
