Patent number: 8767965Abstract: An inventive scheme for detecting parties responsible for repeated malicious activities in secure and anonymous communication is presented. The scheme comprises generating a pool of keys, distributing to and associating with each party a small number of keys chosen randomly from the pool, revoking a key when it is detected as used in a malicious activity, creating a set of parties associated with the revoked key, revoking additional keys randomly chosen among the keys not currently revoked, selecting new keys, and when a party requests an updated key, sending the updated key selected from among the new keys to the requesting party, wherein if an other malicious activity is detected, creating another set of the parties associated with the other malicious activity and identifying the parties in both sets. The steps of the inventive scheme are repeated until only one party is in the intersection set.Type: GrantFiled: July 18, 2008Date of Patent: July 1, 2014Assignee: Telcordia Technologies, Inc.Inventors: Giovanni Di Crescenzo, Tao Zhang, Robert G.

Patent number: 8635681Abstract: A method and system for public key infrastructure key and certificate management provides anonymity to certificate holders and protects the privacy of certificate holders from the compromise of a certificate authority. Functional separation is provided in the authorization of a certificate request and the assignment of certificates and key pairs. The authorizing certificate authority approves or denies each certificate request from a requestor whose identity is not made available to the assigning certificate authority. The assigning certificate authority, upon approval from the authorizing certificate authority, issues one or more certificates and optionally generates and provides the associated key pairs to the requester without disclosing these certificates and key pairs to the authorizing certificate authority.Type: GrantFiled: February 1, 2008Date of Patent: January 21, 2014Assignee: Telcordia Technologies, Inc.Inventors: Tao Zhang, Eric Van Den Berg, Andrew Burnette, Giovanni Di Crescenzo, Richard Ferrer, Stanley Pietrowicz, Robert G.

Patent number: 8363832Abstract: The present invention advantageously provides techniques to solve problems with combinatorial anonymous certificate management by addressing critical issues concerning its feasibility, scalability, and performance. Methods and procedures to manage IEEE 1609.2 anonymous and identifying cryptographic keys and certificates in the Vehicle Infrastructure Integration (VII) system are presented, along with methods for management of identifying and anonymous certificates in a partitioned Certificate Authority architecture designed to enhance vehicle privacy. Novel methods for vehicles to dynamically change an anonymous certificate for use while maintaining vehicle privacy are given. Refinements to basic combinatorial schemes are presented including probabilistic key replacement, rekey counter decrement, dynamic rekey threshold, geographic attack isolation and proofs of geographic position.Type: GrantFiled: March 19, 2008Date of Patent: January 29, 2013Assignee: Telcordia Technologies, Inc.Inventors: Giovanni Di Crescenzo, Stanley Pietrowicz, Eric Van Den Berg, Robert G.

Patent number: 8171283Abstract: The present invention advantageously provides a system and method for management of cryptographic keys and certificates for a plurality of vehicles. Each vehicle of the plurality of vehicles generates public/private key pairs, requests multiple time-distributed certificates, creates an encrypted identity, and surrenders expired certificates. An assigning authority receives the public/private key pairs, the request for multiple time-distributed certificates, the encrypted identity, and the expired certificates from said vehicle. The assigning authority authorizes the vehicle with an authorizing authority, validates the expired certificates, proves ownership, and distributes the requested time-distributed certificates to said vehicle. Validation can comprise checking expired certificates against misused, compromised and/or previously surrendered certificates.Type: GrantFiled: March 19, 2008Date of Patent: May 1, 2012Assignee: Telcordia Technologies, Inc.Inventors: Stanley Pietrowicz, Giovanni Di Crescenzo, Robert G.

Patent number: 6138922Abstract: An electrostatic spray module for applying agricultural liquids such as a pesticide to crops where, externally to the spray module the number of connections is reduced to three, one for the liquid pesticide, one for compressed air and one for a low voltage signal. Internally to the spray module, the low voltage is converted to a high voltage signal, which is, along with the pesticide and the compressed air delivered to one or more electrostatic spray nozzles using only two electrically conductive pipes, a gas delivery pipe and a liquid delivery pipe. The nozzles fit into the gas delivery pipe and draw the compressed air through gas channel openings in the side of the nozzles. The gas delivery pipe doubles as the means to delivery the high voltage signal to the nozzles. Each nozzle has a liquid feed from the liquid delivery pipe, which carries ground voltage, maintaining the liquid at ground voltage. The grounded liquid merges with the compressed air in the nozzles to form an atomized liquid.Type: GrantFiled: November 9, 1999Date of Patent: October 31, 2000Assignee: Progressive Grower TechnologiesInventors: William J. Hartman, Robert G. White

Patent number: 5673322Abstract: An interface between a protected computer or computer network and the World Wide Web (WWW). The interface comprises a split proxy system that encapsulates TCP/IP transmissions into a script transmission, which is not subject to problems in high latency systems, thereby greatly improving WWW access, via a wireless modem or other low-bandwidth communications network. The split proxy interface also provides compression, encryption and filtering capabilities and allows receipt of unsolicited transmissions from the service provider for such purposes as automatically updating or configuring WWW access software.Type: GrantFiled: March 22, 1996Date of Patent: September 30, 1997Assignee: Bell Communications Research, Inc.Inventors: David Mathew Pepe, Lisa B.
