Key Management
One of the key elements of digital security is key management, which involves generating, storing, and using cryptographic keys to secure data and communication. Poor key management can leave sensitive data vulnerable to attacks and compromise the integrity of communication channels.
Two important tools in key management are Physically Unclonable Functions (PUFs) and Random Number Generators (RNGs). PUFs are used to generate unique and unpredictable keys that are virtually impossible to replicate, while RNGs are used to generate random and unpredictable values that are essential for secure cryptographic operations.
SECURYZRTM Physically Unclonable Function (PUF)
PUF IP is a secret key generation system based on Physically Unclonable Functions (PUF). The secret key is extracted by the PUF from the silicon using its unique intrinsic properties caused by tiny manufacturing discrepancies: technological dispersions are amplified into digital signals (bits of information). The key generated by the PUF is not readable but extracted using a group of helper-data. This distinctive feature provides real protection against reverse engineering techniques compared to traditional methods that store the key in non-volatile memory.
