Hardware Root of Trust IP - PUFrt
PUFrt is a Hardware Root of Trust (HRoT) offering the essential features necessary for establishing a trusted foundation from which all security operations, such as secure boot, can be based.
This Riscure certified IP offers the flexibility for users to add only the cryptographic engines that their designs need and comes with a well-designed anti-tamper shell against attacks. PUFrt can be integrated into a wide variety of systems, from a lightweight hardware security key to a full-functioning Security Coprocessor.
PUFrt provides a foundation of trust and security for the chip system. It contains a 1024-bit physical unclonable function (PUF), and a true random number generator (TRNG) that complies with the NIST SP800-90B/SP-800-22 standard specifications. These features aid in the encryption/decryption requirements of sensitive information and data, achieving a higher level of data security protection. Furthermore, an additional 8k-bit secure storage space with PUF is provided for the key or sensitive information injected by the customer, which makes the original security and NeoFuse OTP more resistant to physical attacks.
