Abstract
Systems and methods of generating a security key for an integrated circuit device include generating a plurality of key bits with a physically unclonable function (PUF) generator. Unstable bits of the plurality of key bits are identified, and a security key is generated based on the plurality of key bits, wherein the security key excludes the identified unstable bits.
