An authentication system includes a plurality of electronic tags () that are each associated with a respective unique identity ID. The tags include a memory () with a first memory location () for storing a pre-computed challenge and a second memory location () for storing a pre-computed response that is associated with the challenge. The first memory location () is non-readable from outside the tag. An access circuit () only provides the response after having received a challenge that matches the challenge stored in the first memory location. A reader station () obtains the identity associated with a tag. It then determines a corresponding challenge and sends the challenge to the tag. It receives a response from the tag and verifies the authenticity of the tag by comparing the received response to a response that corresponds to the challenge.
