  • Method and apparatus to provide authentication and privacy with low complexity devices
    Patent number: 8908866
    Abstract: A method and apparatus to provide a cryptographic protocol for secure authentication, privacy, and anonymity. The protocol, in one embodiment, is designed to be implemented in a small number of logic gates, executed quickly on simple devices, and provide military grade security.
    Type: Grant

  • Method and apparatus to provide public key authentication with low complexity devices
    Patent number: 8751806
    Abstract: 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.
