Abstract
Technologies for verification include storage with private keys, wherein each private key is associated with a group affiliation. The storage also includes characteristic information about an apparatus. The technologies also include a wireless interface configured to receive a request from a reader for verification of membership of the apparatus within a group affiliation. The technologies further include a controller with programmable logic for configuring the controller to determine whether to verify membership of the apparatus within a given group affiliation. The controller is also configured to verify membership of the apparatus within the given group affiliation by signing data with a private key associated with the given group affiliation. The signed data is sent to the reader. Membership within the given group affiliation conveys a subset of the characteristic information.
