Filed:

Mar 29, 2010

Appl. No.:

12/748645

Inventors:

Kenneth C. Fuchs - Winfield IL, US
Brian W. Pruss - Streamwood IL, US

International Classification:

G06F 7/04

US Classification:

726 26

Abstract:

Systems and methods for vetting data include receiving a notification at a second processor that a first processor has written first output data to an output data buffer in an output device. A hardware-implemented buffer access flag controls a permission for the first processor to write data to the output data buffer. The second processor sets the hardware-implemented buffer access flag to a first setting that prevents the first processor from writing additional output data to the output data buffer while the first output data in the output data buffer is being inspected. The second processor has a read-write permission to the hardware-implemented buffer access flag. The first processor has a read-only permission to the hardware-implemented buffer access flag.

Abstract:

A key variable loader receives a set of Rijndael parameters that were verified using a simulation computer, wherein the set of Rijndael parameters provide an input for implementing at least one step of the Rijndael block cipher and when used with a secret key allow a conversion between plain text and cipher text using the Rijndael block cipher. The key variable loader further stores the set of Rijndael parameters and subsequently provides the set of Rijndael parameters to a device having a customizable Rijndael block cipher, like a subscriber unit or a key management facility.
