Patent number: 8543822Abstract: A first device in possession of a value is able to determine, without communicating the value and without communicating any information from which the value can be identified, whether a second device is also in possession of the value. The first device accomplishes this with the assistance of a third device that is able to communicate with the first device and with the second device. The second device also does not communicate the value and does not communicate any information from which the value can be identified. The first device may send additional information to the third device which, if passed to the second device, enables the second device to determine that the first device is in possession of the value. The value may be a secret.Type: GrantFiled: March 26, 2012Date of Patent: September 24, 2013Assignee: BlackBerry LimitedInventors: Michael K. Brown, Herbert A. Little, Dinah L. M. Davis

Publication number: 20100106970Abstract: Authentication of two devices in communication with a third device is achieved where the first and second devices each possess a shared secret value. The authentication includes communication of authentication values from the first device to the second device using the third device. Similarly, there is communication of values from the second device to the first device using the third device. The third device retains the communicated values. The values are calculated to permit the third device to authenticate the first and second devices without the third device receiving the shared secret value. The authentication may be used to establish a communications channel between the first and the second devices.Type: ApplicationFiled: January 11, 2010Publication date: April 29, 2010Applicant: RESEARCH IN MOTION LIMITEDInventors: Michael K. BROWN, Herbert A. LITTLE, Dinah L. M. DAVIS
