What's HTTPS for secure computing?

Mike Bursell

Over the past few years, it's become difficult to find a website that is just "http://…" This is because the industry has finally realised that security on the web is "a thing," and also because it has become easy for both servers and clients to set up and use HTTPS connections. A similar shift may be on its way in computing across cloud, edge, Internet of Things, blockchain, artificial intelligence, machine learning, and beyond. We've known for a long time that we should encrypt data at rest (in storage) and in transit (on the network), but encrypting it in use (while processing) has been difficult and expensive. Confidential computing—providing this type of protection for data and algorithms in use using hardware capabilities such as trusted execution environments (TEEs)—protects data on hosted systems or vulnerable environments.
