Abstract:
1. An authorization server comprising: network interface circuitry to receive a resource reservation request from a target access point of a plurality of target access points; processing circuitry to verify a reservation token received from a mobile station and to authorize the target access point to reserve bandwidth thereon when the reservation token is verified, the reservation token being received within the resource reservation request and being provided to the authorization server by the target access point; and a random number generator to generate a challenge value for use by the mobile station in generating a hash chain comprising a predetermined number of reservation tokens, wherein the processing circuitry is configured to verify the reservation tokens by computing and verifying a hash on a received reservation token concatenated with the challenge value, wherein the authorization server is configured to establish a source-authenticated and forgery-protected channel with the access points, and wherein the authentication server uses the predetermined number of reservation tokens to limit a maximum number of target access points on which the mobile station can reserve bandwidth.
