CryptoManager Root of Trust - CryptoManager RISC-V Root of Trust Programmable Secure Processing Core

All Silicon IP


The CryptoManager Root of Trust is a fully-programmable hardware security core that protects against a wide range of attacks with state-of-the-art anti-tamper and security techniques to offer vendors security by design.

How the Root of Trust Works

The CryptoManager Root of Trust is an independent hardware security block for integration into semiconductor devices, offering secure execution of user applications, tamper detection and protection, secure storage and handling of keys and security assets, and resistance to side-channel attacks. The core mitigates against attacks like Meltdown and Spectre by allowing secure processing to be separated from general processing in a siloed architecture. Readily deployable, the Root of Trust is easily integrated with industry-standard interfaces and system architectures and includes hardware cryptographic accelerators for standard algorithms such as AES, SHA, RSA, ECDSA and ECDH. The layered security approach enforces that access and critical operations, including crypto modules, keys, memory ranges, I/O pins, and other resources, are available thru hardware only with no access by software.

The CryptoManager Root of Trust is based on a custom 32-bit RISC-V CPU designed specifically to provide a trusted foundation for secure processing in the core and system. The RISC-V CPU runs signed code modules called containers, which include permissions and security-related metadata. These containers can implement standard security functionality, or complete customer-specific security applications, including key and data provisioning, security protocols, biometric applications, secure boot, secure firmware update, and many more. Part of the comprehensive CryptoManager Security Platform that includes embedded cores, key provisioning infrastructure and infield services, the Root of Trust provides the highest level of end-to-end security at all stages of the chip lifecycle for applications like IoT, automotive, sensors, and connectivity.
