摘要:
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.
