Security Key Management Tool V.1.02 User's Manual
■Roots of trust are highly reliable hardware, firmware, and software components that perform specific, critical security functions. In an IoT system, a root of trust typically consists of identity and cryptographic keys rooted in the hardware of a device. It establishes a unique, immutable, and unclonable identity to authorize a device to exist in the IoT network.
■Secure boot is part of the services provided in the Root of Trust in many security systems. Authentication of the application uses Public Key Encryption. The associated keys are part of the Root of Trust of the system. Device Identity, which consists of Device Private Key and Device Certificate, is part of the Root of Trust for many IoT devices.
■From the above Root of Trust discussion, we can see that leakage of cryptographic keys can bring the secure system into a risky state. Protection of the Root of Trust involves limiting key accessibility to within the cryptographic boundary only, with keys that are securely stored and preferably unclonable. The Root of Trust should be locked from read and write access by unauthorized parties.
■The Renesas user key management system can provide all of the above desired protection.
