  • Decoupling of measuring the response time of a transponder and its authentication
    Patent number: 10044512
    Abstract: Reader (420) for determining the validity of a connection to a transponder (440), designed to measure a response time of a transponder (440) and to authenticate the transponder (440) in two separate steps. Transponder (440) for determining the validity of a connection to a reader (420), wherein the transponder (440) is designed to provide information for response time measurement to said reader (420) and to provide information for authentication to said reader (420) in two separate steps, wherein at least a part of data used for the authentication is included in a communication message transmitted between the reader (420) and the transponder (440) during the measuring of the response time.
    Type: Grant
    Filed: November 3, 2008
    Date of Patent: August 7, 2018
    Assignee: NXP B.V.
    Inventors: Peter Thueringer, Hans De Jong, Bruce Murray, Heike Neumann, Paul Hubmer, Susanne Stern
  • System of providing a fixed identification of a transponder while keeping privacy and avoiding tracking
    Patent number: 9418249
    Abstract: Transponder (180) having stored a fixed identification number, which expands said identification number with a random number, encrypts said expanded number with a key, and sends it to a reader (160) on its request. Reader (160), which on request receives an encrypted number from a transponder (180), decrypts a received encrypted number with a key, which was also used by the transponder (180), and extracts a fixed identification number associated with the transponder (180).

  • Reader and transponder for obscuring the applications supported by a reader and/or a transponder and method thereof
    Patent number: 9384440
    Abstract: Transponder (104), comprising a storage unit (106) having stored a number of different applications, a processing unit (108) which, on request of a reader (102), is adapted to generate a response interpretable using an encryption scheme known by both the transponder (104) and the reader (102) so that the reader (102) is capable of determining whether an application is supported by the transponder (104) by analyzing the response using the encryption scheme, and a transmission unit (110) adapted to send the response to said reader (102).
