Patent number: 8793497Abstract: A puzzle-based protocol is provided that allows a token and verifier to agree on a secure symmetric key for authentication between the token and verifier. A token stores a secret key and one or more puzzle-generating algorithms. The verifier independently obtains a plurality of puzzles associated with the token, pseudorandomly selects at least one of the puzzles, and solves it to obtain a puzzle secret and a puzzle identifier. The verifier generates a verifier key based on the puzzle secret. The verifier sends the puzzle identifier and an encoded version of the verifier key to the token. The token regenerates the puzzle secret using its puzzle-generating algorithms and the puzzle identifier. The token sends an encoded response to the verifier indicating that it knows the verifier key. The token and verifier may use the verifier key as a symmetric key for subsequent authentications.Type: GrantFiled: May 9, 2008Date of Patent: July 29, 2014Assignee: QUALCOMM IncorporatedInventors: Gregory Gordon Rose, Alexander Gantman, Miriam Wiggers De Vries, Michael Paddon, Philip Michael Hawkes

Patent number: 8776739Abstract: A cam can rotate on a camshaft of an internal combustion engine. A rocker arm that actuates a valve of the internal combustion engine can include a rocker pivot connection point located on a distal side of a valve component from a proximate end of the rocker arm that is deflected by action of the cam. The rocker arm can include a contact point located between the rocker pivot point and the proximate end. The contact point can act on the valve component to actuate the valve. The rocker pivot connection point can be translated such that it is closer to or further from the cam. This translation can be used to vary valve lift and/or valve timing. The cam can have a three-dimensional profile to provide different actuation distance of the rocker arm. Systems, methods, and articles of manufacture consistent with one or more of these features are described.Type: GrantFiled: October 10, 2011Date of Patent: July 15, 2014Assignee: Pinnacle Engines, Inc.Inventors: James M.

Patent number: 8726019Abstract: In a communication system in which two communication entities seek to have a private or confidential communication session, a trust relationship needs first be established. The trust relationship is based on the determination of a shared secret which in turn is generated from contextual information. The contextual information can be derived from the circumstances surrounding the communication session. For example, the contextual information can include topological information, time-based information, and transactional information. The shared secret may be self-generated or received from a third party. In either event, the shared secret may be used as key material for any cryptographic protocol used between the communication entities.Type: GrantFiled: February 10, 2006Date of Patent: May 13, 2014Assignee: QUALCOMM IncorporatedInventors: Michael Paddon, Gregory Gordon Rose, James Semple, Philip Michael Hawkes

Patent number: 8625793Abstract: A method for a server to initiate resynchronization with an access terminal, when synchronization has been lost, that cannot be exploited by attackers is provided. The server may provide the access terminal with a secret key that is only known to the access terminal and the server. The access terminal may store the secret key in a secure storage device to prevent the secret key from being hacked. If the server determines that synchronization has been lost, the server may send a resynchronization message to the access terminal with the secret key attached. The access terminal retrieves the stored secret key from the secure memory device and compares it to the secret key attached to the resynchronization message. If there is a match, the access terminal may initiate a secure communication link with the server to reestablish synchronization.Type: GrantFiled: June 9, 2008Date of Patent: January 7, 2014Assignee: QUALCOMM IncorporatedInventors: Philip Michael Hawkes, Andreas K.

Patent number: 8595501Abstract: A network helper is provided that assists verifiers in executing a puzzle-based protocol for authentication of a token. A token stores a secret key and one or more puzzle-generating algorithms. The helper stores a plurality of puzzles associated with a particular token. When requested to do so by a verifier, the helper provides a plurality of pseudorandomly selected puzzles for the token to a verifier. The puzzles are encoded with information that is used between the verifier and token to establish a secured symmetric key. The verifier selects one or a few of the encoded puzzles and breaks them by a brute force attack. Because the helper does not know which puzzles have been selected, it has to break all puzzles to attempt to figure out the symmetric key. However, if a large number of puzzles are utilized, say millions, then breaking all of them becomes a computationally prohibitive task.Type: GrantFiled: May 9, 2008Date of Patent: November 26, 2013Assignee: QUALCOMM IncorporatedInventors: Gregory Gordon Rose, Alexander Gantman, Miriam Wiggers De Vries, Michael Paddon, Philip Michael Hawkes
