A method and apparatus to authenticate limited processing-power systems (LPPS) using elliptic cryptography within a well known elliptic curve E, over a well known finite field F((E(F)). The apparatus comprises a random number generator to choose a random value b, of a similar order of magnitude to the order of E(F). The apparatus further comprises a challenge calculator to calculate a value C=bP and send the challenge to the LPPS, where P is a point on the elliptic curve E(F) which was used as a basis for generating a private key, a, for the LPPS. The apparatus further comprising an RFID reader to receive a challenge response, R=aC=abP from the LPPS, and a crypto calculator to calculate bQ, based on a public key, Q, of the LPPS. The apparatus further comprising a comparison logic to authenticate the LPPS if bQ=aC=abP.
