KEY MANAGEMENT SYSTEM PROVIDING SECURE MANAGEMENT OF CRYPTOGRAPHIC KEYS, AND METHODS OF OPERATING THE SAME

A method of operating the physically unclonable function (PUF)-based key management system (1) includes a load balancer (14) dispatching a key generation request including a parameter from an external device according to workloads of a plurality of key management components (KMCs) (101 to ION). A KM...

Zusammenfassung:A method of operating the physically unclonable function (PUF)-based key management system (1) includes a load balancer (14) dispatching a key generation request including a parameter from an external device according to workloads of a plurality of key management components (KMCs) (101 to ION). A KMC having minimum workload among the plurality of KMCs (101 to ION) is designated as a key-generation KMC and the key generation request is dispatched thereto, and remaining KMCs of the plurality of KMCs (101 to ION) are designated as backup KMCs. The method further includes the key-generation KMC generating a key according to the parameter and a first PUF sequence, transmitting the key and an identifier associated therewith to the backup KMC via a backup channel (16), and the backup KMC generating a wrapped key according to the key and a second PUF sequence.
