Filed:

Oct 15, 2002

Appl. No.:

10/272414

Inventors:

Jeffrey S. Andrews - Norcross GA, US

Assignee:

Arris International, Inc. - Suwanee GA

International Classification:

H04M 3/00

US Classification:

455419, 455418, 3793991

Abstract:

A method and system for using a database that associates a specific set of line interface specifications to a specific design requirement. The design requirement may correspond to a particular country's telephony operating requirements, or one of multiple sets of operating requirements within a country. This allows loading of generic line interface data at manufacturing. Specific criteria can be provided to the line interface at installation and/or startup. The database contains the specifications for all potential operating requirements, and a template code, sent to a line interface device from a central controller, is used to determine the corresponding set of line interface specifications from the database, which is indexed on template code.

Jeffrey A. Andrews - Sunnyvale CA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 9/26
G06F 9/34
G06F 12/00

US Classification:

711211, 713164, 713190

Abstract:

A integrity control system uses the address bits to enable protection of data stored in a system memory. An address bus that determines the location of data to be stored or retrieved from system memory has a plurality of address lines. A subset of the address lines enables the protection mechanism to generate an integrity control value representative of the data and determine where the integrity check value is stored in a secure memory.

International Classification:

H04L 9/32
H04L 9/00

US Classification:

713189, 713193, 713181

Abstract:

A integrity control system uses the address bits to enable encryption and/or protection of data stored in a system memory. The encryption and protection mechanisms are coupled to the CPU by way of a data bus and to the memory by way of a data bus. An address bus that determines the location of data to be stored or retrieved from system memory has a plurality of address lines. At least one of the address lines enabling the encryption mechanism to encrypt data before storage in the memory and to decrypt data after retrieval from memory. Another address line enables the protection mechanism to generate a hash of the data. The hash is stored and used to determine whether data has been altered while stored in system memory.

Inventors:

Dinarte R. Morais - Redmond WA, US
Jeffrey A. Andrews - Sunnyvale CA, US

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 9/32

US Classification:

711207, 711200, 711202

Abstract:

A computing environment maintains the integrity of data stored in system memory. The system has a memory management unit that maintains a plurality of real page numbers. The system also comprises an address bus in communication with the memory management unit. The address bus comprises a plurality of address lines, wherein a value of at least one address line is set by a real page number from the memory management unit. The system has an operating system that controls memory usage by controlling the real page numbers stored in said page table that is accessed by the memory management unit. At least one security feature such as data encryption is selectively applied to data stored in a page of said memory as enabled by a value of said address line set by said real page number.

Inventors:

Jeffrey S. Andrews - Norcross GA, US

Assignee:

ARRIS Group, Inc. - Suwanee GA

International Classification:

H04M 3/00

US Classification:

370359, 4554322, 4554352, 4555521, 455419, 455466, 370352, 37922114

Abstract:

A database correlating a specific set of linecard criteria, out of a plurality of sets of linecard criteria, to a template code is loaded into a linecard during manufacturing. A template code based on country-specific criteria is sent to the linecard at startup, whenever otherwise desired. The template code may also be periodically refreshed from a central authority that recognizes the address of a particular linecard.

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 11/30

US Classification:

713190, 713194, 711164, 711216, 726 22

Abstract:

A computing environment maintains the confidentiality of data stored in system memory. The computing environment has an encryption circuit in communication with a CPU. The system memory is also in communication with the encryption circuit. An address bus having a plurality of address lines forms part of the system and a value of at least one of the address lines determines a key selected from a plurality of keys to use in the encryption circuit to encrypt data being transferred by the CPU to the memory.
