With NeoPUF as the core, PUFrt provides a foundation of trust and security for the chip system. It also provides a 1024-bit identification code with a physical unclonable function(PUF) and a true random number generator(tRNG) that complies with the NIST SP800-90B/SP-800-22 standard specifications. These help meet the encryption/decryption requirements of sensitive information and data, and achieve a certain level of data security protection. An additional 4096-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.
