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.

The Cyber Resilient Module and Building Block Requirements Version 1.0 Revision 0.2 specification has been published in August 2022, introducing the overall CyRes architecture, requirements for an initial set of CyRes building blocks such as watchdogs and latches, as well as several CyRes module profiles for different industry scenarios. Currently, the CyRes workgroup is working on a second version of the specification, seeking to include support for persistent resilience engines that are active after the boot process is completed, as introducing improved CyRes building blocks, as well as reorganizing the specification to align content to various roles such as engineering, architecture, product management, and technology consumers.
