Filed:

Aug 19, 1999

Appl. No.:

09/377288

Inventors:

Christopher Paul Carroll - Framingham MA

Assignee:

Verizon Laboratories Inc. - Waltham MA

International Classification:

H04M 300

US Classification:

455419, 455420

Abstract:

A system includes at least one wireless communications device having a standard wireless interface and a wireless provisioning device that provisions the wireless communications device. The wireless provisioning device uses the standard wireless interface to transfer the provisioning information, including an authentication key, to the wireless communications device when both devices are interconnected via a wireline link between a transceiver antenna of the wireless communications device and a communication unit of the provisioning device.

Christopher Paul Carroll - Framingham MA
Yair Frankel - Westfield NJ

Assignee:

Verizon Laboratories Inc. - Waltham MA

International Classification:

H04L 900

US Classification:

713171, 455410

Abstract:

An escrowed key distribution system for over-the-air service provisioning of cellular telephones and other wireless communication devices provides a secure and efficient authentication key distribution method for wireless communications networks. To ensure security, an authentication key used to activate the wireless device is never transmitted over the air. In addition, mutual authentication is performed between the wireless communication device and the service provider using an embedded private-key algorithm to ensure proper authentication key transfer.

Assignee:

Verizon Laboratories Inc. - Waltham MA
Genuity, Inc. - Cambridge MA

International Classification:

H04L009/00

US Classification:

380 44, 380 46

Abstract:

Methods and systems are provided for processing information. In one embodiment, there is provided a method, providing a frame key based on a master key and a frame number of a frame of information to a keystream generator as an initial fill for one or more registers of the keystream generator such that the initial fill establishes a state for the one or more registers of the keystream generator; and generating, at the keystream generator, a keystream sequence based on the state established by the initial fill, wherein the keystream sequence includes a modulo-2 sum of a lagged-Fibonacci sequence and a pseudo-random sequence produced by a filter generator.

Filed:

Nov 9, 2000

Appl. No.:

09/710541

Inventors:

Christopher Paul Carroll - Framingham MA, US

Assignee:

Verizon Laboratories Inc. - Waltham MA

International Classification:

H04L 9/00
H04K 1/00

US Classification:

713171, 713168, 713170, 380230, 380247, 380262, 380277

Abstract:

Techniques are described for enabling authentication and/or key agreement between communications network stations and service networks. The techniques described include the negotiation and use of a cryptographic primitive shared between a service network and a home environment of a station. The techniques described also feature a key usage indicator, such as a sequence number, maintained by the service network and a station. Comparison of the key usage indicators can, for example, permit efficient authentication of the service network.

US Classification:

713169, 713171, 713182, 726 5, 380247, 380278, 380282, 380 44, 455410, 455411

Abstract:

Systems and methods disclosed herein provide secure, efficient, and mutually authenticated cryptographic key distribution. A client or client manufacturer may pre-generate and pre-encrypt the cryptographic keys, store the encrypted keys within the client, and deliver such keys to the serving network's access server via the client, while also relying upon, if available, the authentication performed by a trusted access server of an intermediate network which the client must traverse in order to obtain access the serving network. If not available, a client password stored within the client may be used to enable client authentication by the serving network prior to acceptance of the delivered cryptographic keys.

Filed:

Dec 8, 2011

Appl. No.:

13/314413

Inventors:

Christopher Paul Carroll - Framingham MA, US

International Classification:

G06F 17/30

US Classification:

707602, 707E17005

Abstract:

The application describes systems and methods for preventing the distribution of large volumes of electronic data by loading selected sensitive files with pad data to increase the size of the files such that file transfer, distribution, or downloading to removable media storage devices is more cumbersome. In one aspect, a file loading system comprises a datastore for storing a plurality of data files where each of the plurality of data files includes information and a processor arranged to: access the plurality of data files in the datastore, and load a data pad into one or more of the plurality of data files to increase the size of the one or more of the plurality of data files.

International Classification:

G06F 17/30
G06F 21/62
H04L 29/06
G06F 21/10

Abstract:

The application describes systems and methods for loading a data file with a data pad having a pattern that enables identification of the data file during certain file operations. In one aspect, a file loading system comprises a datastore configured to store a plurality of data files where the plurality of data files include a plurality of original data files and at least one loaded data file. The system also includes a removable media storage device capable of interfacing with the datastore. The system further includes a processor arranged to access the plurality of data files in the datastore and convert a first original data file of the plurality of original data files into a first loaded data file. The first loaded data file includes information and a first data pad of added data. The first data pad includes a first pattern of data elements. The processor also monitors operations associated with the plurality of data files to detect a first data transfer operation from the datastore to the removable media storage device. Furthermore, the processor identifies a data file associated with the first data transfer operation as the first loaded data file by detecting the first pattern of data elements within the data file associated with the first data transfer operation.
