PUF is a hardware security technology based on physically uncloneable variations occurring in the silicon manufacturing process. The underlying benefit of using a PUF (Physical Uncloneable Function) in cryptography is its “uniqueness” and “unpredictability”. With PUF IP, users can generate truly random sequences for applications with high security requirements. Socle provides innovative technology enables multi-layered security and resolves common PUF-related issues by eliminating the need for a costly and complicated ECC (Error Correction Code). The random number extracted by PUF IP is unique and uncloneable, a silicon “fingerprint” for a wide range of security purposes, including encryption, identification, authentication, security key generation, etc.
