INTEGRATED DEVICE FOR IMPLEMENTING A PHYSICAL UNCLONABLE FUNCTION AND A PHYSICAL UNCLONABLE CONSTANT

摘要

A PUC (Physical Unclonable Constant) cell characterized by a very low complexity comparable to that of an SRAM cell and by much greater reliability than an SRAM cell as it is characterized by only one stable equilibrium point the position of which depends on random differences introduced during the step of manufacturing the chip. The PUC cell according to the present invention is also stable over a wide range of operating temperatures and offers considerable noise immunity, thus making the use of stabilizers adapted to ensure the correct output and which are normally used along with conventional SRAM type cells unnecessary.
