Verayo secures PUF license from MIT
PUF-based key generation significantly elevates security and trust in cryptography-based solutions. Current state-of-the-art cryptography is based on keys that are typically stored on-chip (cf. Smart Insights Weekly #09-48). These keys are then used to authenticate and encrypt sessions for various applications such as identification, access control or financial transactions. With PUFs, Verayo says such cryptographic solutions can provide a higher level of security and trust by dynamically generating chip-unique (or shared) volatile, though robust/reproducible, cryptographic keys, instead of storing and securing these keys. Additionally, a PUF-based cryptography solution can generate multiple, volatile secret root master keys even after being deployed in the field. This allows PUF-based cryptography solutions to renew root master keys in the field or support multiple vendors, features and functions.
