Abstract

See full text

A method of operating the physically unclonable function (PUF)-based key management system includes upon receiving a key generation request including a parameter, a load balancer dispatching a key generation request including a parameter from an external device according to workloads of a plurality of key management components (KMCs). A KMC having minimum workload among the plurality of KMCs is designated as the key-generation KMC and the key generation request is dispatched thereto, and remaining KMCs of the plurality of KMCs 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, and the backup KMC generating a wrapped key according to the key and a second PUF sequence.
