Abstract
A security system with entropy bits includes a physically unclonable function circuit, and a security key generator. The physically unclonable function circuit provides a plurality of entropy bit strings. The security key generator generates a security key by manipulating a manipulation bit string derived from the plurality of entropy bit strings according to an operation entropy bit string. Each bit of the operation entropy bit string is used to determine whether to perform a corresponding operation to the manipulation bit string.
