Filed:

Jul 29, 2010

Appl. No.:

12/845738

Inventors:

Hal A. Aldridge - Tampa FL, US
Keith R. Thal - Tampa FL, US

Assignee:

Sypris Electronics, LLC - Tampa FL

International Classification:

H04L 29/06

US Classification:

713153

Abstract:

A network extension device comprising a CPU, memory, protected I/O connectable to local controls and peripherals, external communications port, a trusted device connected to the CPU such that it can provide attestation of the network extension device's trusted operation to a connected known external network, and a protected interface connected to at least one network extension module that includes a local network communications port. Optionally, a traffic encryption module may be provided, and the trusted device's attestation may include a check of its operation. Also, a method comprising connecting the network extension device to an external network, performing an operating mode check, causing the network extension device to operate in a mode and perform a security check that correspond to the result, causing the trusted device to attest trusted operation to the external network and thereafter causing the CPU to function fully and permitting access to the external network.

Inventors:

John J. Walsh - Lutz FL, US
Michael J. Duren - Clearwater FL, US
Hal A. Aldridge - Tampa FL, US

International Classification:

G06F 21/00

US Classification:

726 2

Abstract:

A resilient device authentication system comprising: one or more verification authorities (VAs) including a memory loaded with a complete verification set that includes hardware part-specific data, and configured to create a limited verification set (LVS) therefrom; one or more provisioning entities (PEs) each connectable to at least one of the VAs, including a memory loaded with a LVS, and configured to select a subset of data therefrom so as to create an application limited verification set (ALVS); and one or more device management systems connectable to at least one of the PEs, including a memory loaded with an ALVS, and configured to manage device security-related applications through the performance of security-related functions on devices associated with the hardware part-specific data.

Appl. No.:

15/996575

Inventors:

Hal A Aldridge - Raleigh NC, US
John T. Orr - Raleigh NC, US

International Classification:

G06F 21/57
G06F 11/36

Abstract:

A system and method for testing for software vulnerabilities within components installed within a compartmentalized testing environment is presented herein. The system allows software code to be run within a software simulation environment, providing representative signals, whether Radio Frequency, microwave, or other portions of the electromagnetic spectrum, to test signals to the component under test while its execution is monitored and controlled within the compartmentalized testing environment. The system and method is particularly effective for searching for and identifying vulnerabilities to combined Cyber/Electronic Warfare attacks.

Assignee:

Sypris Electronics, LLC - Tampa FL

International Classification:

G06F 12/14
H04L 9/32
G06F 21/44

Abstract:

A resilient device authentication system for use with one or more managed devices each including a physical unclonable function (PUF), comprises: one or more verification authorities (VA) each including a processor and a memory loaded with a complete verification set (CVS) that includes hardware part-specific data associated with the managed devices' PUFs and metadata, the processor configured to create a limited verification set (LVS) through one-way algorithmic transformation of hardware part-specific data together with metadata from the loaded CVS so as to create a LVS representing both metadata and hardware part-specific data adequate to redundantly verify all of the hardware parts associated with the LVS; and one or more provisioning entities (PE) each connectable to a VA and including a processor and a memory loaded with a LVS, and configured to select a subset of the LVS so as to create an application limited verification set (ALVS). The system may also comprise one or more device management systems each connectable to a PE and to managed devices and including a memory configured to store an ALVS. The VA may also be configured to create a replacement LVS.
