Secure storage of a codeword within an integrated circuit
Abstract:
The invention discloses an integrated circuit (10) for securely storing a codeword. The value of the codeword is dependent on the mobility (μA, μB, μC) of at least one transistor (TRA, TRB, TRC) of the integrated circuit. The invention further discloses a reader means (15), a method for determining the value of the codeword from the integrated circuit (10), and a method for altering the value of the codeword.
Abstract(Chinese):

本发明公开了一种用于安全地存储码字的集成电路（10）。 码字的值取决于集成电路的至少一个晶体管（TRA，TRB，TRC）的迁移率（μA，μB，μC）。 本发明还公开了一种读取器装置（15），一种用于从集成电路（10）确定码字的值的方法，以及用于改变码字值的方法。
