US Patent:

7360241, Apr 15, 2008

Filed:

Aug 3, 2001

Appl. No.:

09/920801

Inventors:

Taher Elgamal - Palo Alto CA, US
Jeff Weinstein - Los Gatos CA, US
Nelson Bolyard - Milpitas CA, US

Assignee:

Netscape Communications Corporation - Mountain View CA

International Classification:

G06F 9/00

US Classification:

726 11, 726 1, 726 2

Abstract:

Method, apparatus, system, and a file for integrated dynamic encryption and/or decryption for use in an application includes, for example, storage means or unit for storing a plurality of predetermined attributes and corresponding values, and a digital signature, a controller or control means for controlling selective retrieval of a plurality of attributes and values, and the digital signature from the storage unit, processing means or processor for selectively processing the predetermined attributes and values, and the digital signature and in accordance thereto, providing a supportable encryption and/or decryption level to the application, a compressor or compression means for compressing the attributes and values and in accordance thereto generating compressed attributes and values for storing in the storage unit, and decompressing means or decompressor for decompressing the compressed attributes and values in accordance with the controller retrieving the compressed attributes and values.

International Classification:

G06F 1/26
G06F 17/00

US Classification:

700295, 700 90

Abstract:

To provide overall security to a utility management system, critical command and control messages that are issued to components of the system are explicitly approved by a secure authority. The explicit approval authenticates the requested action and authorizes the performance of the specific action indicated in a message. Key components of the utility management and control system that are associated with access control are placed in a physical bunker. With this approach, it only becomes necessary to bunker those subsystems that are responsible for approving network actions. Other management modules can remain outside the bunker, thereby avoiding the need to partition them into bunkered and non-bunkered components. Access to critical components of each of the non-bunkered subsystems is controlled through the bunkered approval system.

Appl. No.:

16/001084

Inventors:

- San Jose CA, US
Nelson Bolyard - San Jose CA, US
Winston Lew - San Jose CA, US

Assignee:

ITRON NETWORKED SOLUSTIONS, INC. - San Jose CA

International Classification:

G06F 21/74
G01D 4/00
G06F 21/82

Abstract:

A communications device has a first communications port via which secure messages are received, and a second communications port via which non-secure messages are received. In response to detecting that a secure message has been received, the device determines whether the second communications port is in a state that enables non-secure messages to be received. If the second communications port is in the enabled state, the device autonomously disables the second communications port to preclude non-secure messages received at that port from being processed.
