    摘要： A method for producing a security device includes providing at least one stochastic selector, generating a coupling between an identifier and one particular combination of security features from a finite set of distinct combinations of security features based on the at least one stochastic selector, registering the coupling in a database, and applying an identification element including the identifier and a non-printable security element including the particular combination of security features according to the coupling to a substrate to produce a security device.

    摘要： A license authentication device for a semiconductor manufacturing apparatus that provides a licensed function includes: an acquiring unit that acquires first information and second information from the semiconductor manufacturing apparatus; a first authentication information generating unit that generates first authentication information based on the first information and the second information acquired by the acquiring unit; and a usage authority determining unit that, when the first authentication information generated by the first authentication information generating unit and the first authentication information stored in advance in the license authentication device are not identical to each other, restricts use of the licensed function in the semiconductor manufacturing apparatus.

    摘要： Methods and apparatus for creating a physically unclonable function for SRAM are disclosed. An example method includes decreasing a supply voltage of a memory array to a first voltage level, the first voltage level being below a normal operating voltage associated with the memory array, reading a first value of a bit cell after the supply voltage has been at the first voltage level, and determining a function based on the first value of the bit cell and a second value, the second value stored in the bit cell when the memory array is operating at a voltage level above the first voltage level, the function to represent an identification of a circuit including the memory array.

    摘要： Systems, apparatuses, and methods to secure identity chaining between software/firmware components of trusted computing base. A memory device includes a secure memory region having access control based on cryptography. The secure memory region stores component information about a second component configured to be executed after a first component during booting. Prior to using a component identity of the second component to generate a compound identifier of the first component, health of the second component to be executed is verified based on the component information stored in the secure memory region.
