Our Core Technologies & Standards
TCG technologies form the foundation of hardware-based security across industries and devices.
Each specification is developed by our Work Groups and freely available to manufacturers, developers and integrators worldwide. Browse the full list below to explore our core technologies and standards.
All Technologies
Trusted Platform Module (TPM)
TCG's standardized hardware Root of Trust for protecting keys, recording platform measurements and supporting attestation across every class of device.
Block Integrated Trust (BIT)
TCG's component-level hardware Root of Trust for constrained devices, giving integrated components their own identity and attestation.
Storage Security
TCG's architecture for interoperable security on trusted storage devices: self-encrypting drives, access control, locking and Opal, Ruby and Opalite classes.
Cyber Resilient Technologies (CyRes)
TCG's cyber-resilience technology for protecting persistent code, detecting unexpected states and recovering platforms to a known trusted state.
Platform Certificates
TCG's provenance artifacts asserting Roots of Trust, Trusted Building Blocks and component composition for supply-chain assurance.
TPM Software Stack (TSS)
TCG's standardized TPM software access layer, providing vendor-neutral APIs so applications can use TPM capabilities on any implementation.
Reference Integrity Manifest (RIM)
Signed, machine-readable reference measurements used to verify a device boots and runs in its expected, trusted state.
Device Identifier Composition Engine (DICE)
TCG's lightweight hardware Root of Trust for device identity and attestation, built for constrained devices and components.
