Major tech companies including Alibaba, Arm, Baidu, IBM, Intel, Google Cloud, Microsoft, and Red Hat today announced intent to form the Confidential Computing Consortium to improve security for data in use. Established by the Linux Foundation, the organization plans to bring together hardware vendors, developers, open source experts, and others to promote the use of confidential computing, advance common open source standards, and better protect data.
“Confidential computing focuses on securing data in use. Current approaches to securing data often address data at rest (storage) and in transit (network), but encrypting data in use is possibly the most challenging step to providing a fully encrypted lifecycle for sensitive data,” the Linux Foundation said today in a joint statement. “Confidential computing will enable encrypted data to be processed in memory without exposing it to the rest of the system and reduce exposure for sensitive data and provide greater control and transparency for users.”
The consortium also said the group was formed because confidential computing will become more important as more enterprise organizations move between different compute environments like the public cloud, on-premises servers, or the edge.
To get things started, companies made a series of open source project contributions including Intel Software Guard Extension (SGX), an SDK for code protection at the hardware layer.
June 5th: The AI Audit in NYC
Join us next week in NYC to engage with top executive leaders, delving into strategies for auditing AI models to ensure fairness, optimal performance, and ethical compliance across diverse organizations. Secure your attendance for this exclusive invite-only event.
Microsoft contributed the Open Enclave SDK for developers to build Trusted Execution Environment (TEE) applications, and IBM’s Red Hat is sharing Enarx for running TEE applications.
As enterprise customers demand more data security, approaches like confidential computing or federated learning could grow in adoption among machine learning practitioners. For example, in a Confidential Computing Challenge competition held by Google Cloud earlier this year, first place went to TF Trusted, a project that brings together the TensorFlow machine learning framework, confidential computing, and the Asylo framework.
