Reliable unit with a physically unclonable function for an access entitlement test of the safe unit and a method for the production thereof.

摘要

A method (300) for producing a reliable unit with a physically unclonable function, wherein the method (300) comprises:Providing an integrated circuit, the at least one high - k / metal - gate - unit, which the at least one high - k / metal - gate - unit, the function which is not physically clone represents (310, 320);Varying a state of the environment, which the at least one high - k / metal - gate - unit (110) is subjected to during the forming, in order to achieve a variation in a physical property of the at least one high - k / metal - gate - unit to produce specifically can be measured relative to variations in physical properties of other high - k / metal - gate - units is to the at least one high - k / metal - gate - unit were produced in a common charge, and wherein from the physical property is known that they sensitive to variations in the state of the environment; andInclude of a measuring circuit (120; 200) in the integrated circuit, which is configured such that the physical property of the at least one high - k / metal - gate - unit for an access entitlement test of the safe unit measures (350, 360), wherein the at least one property is influenced by the specific variation.
