SECURE LOGIC SYSTEM WITH PHYSICALLY UNCLONABLE FUNCTION

The invention disclose a secure logic system, and the secure logic system includes a physically unclonable function, a physically unclonable function configuration register, and an encryption circuit.The physically unclonable function establishes an encryption string according to at least partial random physical characteristics of the physically unclonable function. The physically unclonable function configuration register is coupled to the physically unclonable function, and load the encryption string from the physically unclonable function. The encryption circuit is coupled to the physically unclonable function configuration register, and manipulates a system string with the encryption string to generate encrypted data. 本发明公开了一种安全逻辑系统。安全逻辑系统包括物理不可克隆函数装置、物理不可克隆函数缓存器及加密电路。物理不可克隆函数装置根据物理不可克隆函数装置的至少一部分随机物理特征建立加密字符串。物理不可克隆函数缓存器耦接于物理不可克隆函数装置，并自物理不可克隆函数装置载出加密字符串。加密电路耦接于物理不可克隆函数缓存器，并利用加密字符串来操作系统字符串以产生加密数据。
