Crypto Coproccesor IP - PUFcc
PUFcc is a novel high-security Crypto Coprocessor. Compared to traditional security SoC design (embedded HSM with secure core or discrete crypto components), PUFcc can provide a much easier to adopt hardware RoT with less vulnerability. As a result, PUFcc quickly improves the security level for any system without additional loading on the processor core or operating system.
The security boundary for PUFcc is quite robust, based on physical separation of hardware, with less vulnerability than a software-only barrier. The on-board PUF is a naturally well-protected source of static entropy, suitable for SoC architects to build a system’s key hierarchy using established key generation and management procedures. In addition, PUFcc’s crypto engines can perform a wide variety of secure operations, such as key exchange, secure boot or TLS (public key validation and signing), authentication (MAC), or key wrapping (again based on the natural randomness inherent to the PUF) and store said wrapped keys to external memory.
