Programmable Root of Trust with Quantum Safe Cryptography acceleration, DPA-resistant & FIA-protected cryptographic accelerators and Caliptra RoTM

The CryptoManager RT-6xx v3 Root of Trust family from Rambus is the latest generation of fully programmable FIPS 140-3 compliant hardware security cores offering Quantum Safe security by design for data center and other highly secure applications.

Device and system architects face a growing array of security threats, including the threat of quantum computers. Across applications, one constant is the need for a hardware Root of Trust-based security implementation.

The CryptoManager RT-6xx family protects against a wide range of hardware and software attacks through state-of-the-art side channel attack countermeasures and anti-tamper and security techniques. The RT-6xx supports various security certifications up to level 3. The RT-6×4 Root of Trust adds Quantum Safe Encryption (QSE) to provide a future-proof hardware security solution to protect data center assets starting today and into the quantum era.

The RT-6xx allows customers to develop secure and trusted applications that run securely within a trusted boundary. Secure applications can be assigned unique roots and keys, allowing independent permissions and access levels.

How the CryptoManager RT-6xx Root of Trust Works

The CryptoManager RT-6xx Root of Trust is a siloed hardware security IP core for integration into semiconductors, offering secure execution of authenticated user applications, tamper detection and protection, secure storage and handling of keys and security assets, and optional resistance to side-channel attacks. The Root of Trust is easily integrated with industry-standard interfaces and system architectures and includes standard hardware cryptographic cores. Access to crypto modules, keys, memory ranges, I/O, and other resources is enforced in hardware. Critical operations, including key derivation and storage, are performed in hardware with no access by software. The Root of Trust is based on a custom 32-bit processor designed specifically to provide a trusted foundation for secure processing on chip and in the system. The RT-6xx inherits its flexible cryptographic accelerator from the embedded Rambus CryptoManager Hub CH-6xx cores.

The Root of Trust supports all common host processor architectures including ARM, RISC-V, x86 and others. The multi-threaded secure processor runs customer developed signed code either as a monolithic supervisor or as loadable security applications which include permissions and security-related metadata. It can implement standard security functionality provided by Rambus, or complete customer-specific security applications, including key and data provisioning, security protocols, biometric applications, secure boot, secure firmware update, and many more.
