Methods for authenticating a property of an article in electrical communication with a verifier system including, for example, reading an identification code from the article, generating a challenge phrase from a verifier system, writing a challenge phrase to a first memory location on the article, reading a response phrase from the second memory location on the article, wherein the second memory location is configured to respond with a combinational logic gate output of the second memory location and the first memory location, generating a message authentication code by encrypting the identification code using a predetermined algorithm, generating a comparison code, wherein the comparison code is a combination logic gate output of the message authentication code and the challenge phrase, and determining if the comparison code is equivalent to the response phrase. Articles configured for use with the same.
