    摘要: The invention relates to a semiconductor device comprising a physical structure (50) for use in a physical unclonable function, wherein the physical structure (50) comprises a lead-zirconium titanate layer (25), and a silicon-comprising dielectric layer (27) deposited on the lead-zirconium-titanate layer (25), wherein the silicon-comprising dielectric layer (27) has a rough surface (SR), the physical structure (50) further comprising a conductive layer (30) provided on the rough surface (SR) of the silicon-comprising dielectric layer (27). The invention further relates to a method of manufacturing such semiconductor device. The invention also relates to a card, such as a smartcard, and to a RFID tag comprising such semiconductor device. The inventors have found that depositing of a silicon- comprising dielectric layer (27) on a lead-zirconium titanate layer (25) using vapor deposition results in a silicon-comprising dielectric layer (27) having a rough surface (SR). This rough surface (SR) can be used in a PUF to make a resistor (R) with a variable random value by depositing a conductive layer (30) on the rough surface (SR). Alternatively, the combination of both layers (25, 27) can be used in a PUF as composite dielectric to make a capacitor (C) with a variable random capacitance value.

    摘要: The invention relates to a method for proving authenticity of a prover PRV to a verifier VER, the method comprising generating a secret S using a physical token by the prover PRV. Obtaining a public value PV by the verifier, where the public value PV has been derived from the secret S using a function for which the inverse of said function is computationally expensive. The method further comprising a step for conducting a zero knowledge protocol between the prover PRV and the verifier VER in order to prove to the verifier VER, with a pre-determined probability, that the prover PRV has access to the physical token, where the prover PRV makes use of the secret S and the verifier VER makes use of the public value PV. The invention further relates to a system employing the method, and an object for proving authenticity.
