Our Core Technologies & Standards

View all Technologies

Block Integrated Trust (BIT)

Brings trusted computing principles to block-level storage, enabling integrity, attestation, and protection of data blocks at the device layer.

Cyber Resilient Technologies (CyRes)

TCG's cyber-resilience technology for protecting persistent code, detecting unexpected states, and recovering platforms to a known trusted state.

Device Identifier Composition Engine (DICE)

Device Identifier Composition Engine establishes a unique cryptographic identity for resource-constrained devices and IoT systems with minimal hardware.

Platform Certificates

TCG's provenance artifacts asserting Roots of Trust, Trusted Building Blocks, and component composition for supply-chain assurance and attestation appraisal.

Reference Integrity Manifest (RIM)

Signed, machine-readable reference measurements used to verify a device boots and runs in its expected, trusted state.

Storage Security

TCG's architecture for interoperable security on trusted storage devices: self-encrypting drives, access control, locking, and Opal, Ruby, and Opalite classes.

TPM Software Stack (TSS)

A consistent software interface that lets applications and operating systems interact with TPM hardware across vendors, architectures, and platforms.

Trusted Platform Module (TPM)

Hardware-based root of trust that securely generates and stores cryptographic keys, attesting to the integrity of the platform it runs on.
