ARCA Trusted OS for Clouds is a hardened operating system designed to provide a trusted and robust execution environment for containers running in virtualized cloud infrastructures. It addresses security and privacy concerns in public, private, and hybrid cloud deployments by combining hardware-based security mechanisms with encryption. Key operational characteristics: - Encrypts data in persistent storage within virtual machines, complementing confidential computing's in-memory encryption - Isolates encryption keys from cloud service provider (CSP) administrators, preventing unauthorized access - Supports hardware root of trust attestation at each VM boot, verifying both the confidential computing enablement and the integrity of the OS - Extends trusted execution environments (TEE) across hybrid architectures to maintain consistent security and data confidentiality The product has been qualified for major public cloud platforms including Google Cloud Platform and AWS (conventional VMs and AMD EPYC-based VMs), with Azure support under evaluation. It also supports on-premises hypervisors including VMware ESXi/vSphere, QEMU/KVM, and Oracle VirtualBox. ARCA Trusted OS is positioned to help organizations host sensitive workloads in untrusted cloud environments by ensuring that neither the cloud provider nor its administrators can access data or cryptographic keys.
