Patent number: 10356129Abstract: A system and method for updating multiple devices that are coupled to a network by a hub provides a trusted platform module in each of the devices, sends messages from the network to the hub for updating the devices, sends each of the devices messages from the hub to update the device, executes the content of each message in the device to which that message is sent, and deletes each message after it has been executed. Each of the messages preferably includes trusted code, and the device receiving each message executes the trusted code in the trusted platform module. The trusted code may include an update function, an image, and control data, and preferably has integrity. The hub may receive trusted code from a remote server, execute the trusted code to send a message to one of the devices, and then delete the trusted code.Type: GrantFiled: January 24, 2018Date of Patent: July 16, 2019Assignee: Synopsys, Inc.Inventors: Andrew Elias, Derek Bouius, Neil Leckett, Steven Lougheed

Patent number: 9794623Abstract: A method for determining the color depths of the video data for a selected frame in High-bandwidth Digital Content Protection (HDCP) video data transmitted over a High Definition Multimedia Interface (HDMI), in which (a) the beginning of the selected frame is marked with a vertical synchronization (VSYNC) signal and (b) a mark in a window of opportunity (WOO) for the selected frame indicates whether or not that frame is encrypted. The method detects, for the selected frame, the length of the interval between a VSYNC signal and the location of at least one of (i) the start of the corresponding WOO and (ii) the mark indicating whether or not the selected frame is encrypted, and then determines the color depth of the video data for the selected frame based on the detected length.Type: GrantFiled: April 14, 2014Date of Patent: October 17, 2017Assignee: Synopsys, Inc.Inventors: A.

Patent number: 9264229Abstract: A method for performing a cryptographic function on text to generate converted text comprises producing a random key stream having a first block size in a first frequency domain; converting the random key stream having a first block size in the first frequency domain to a random key stream in a second frequency domain; converting the random key stream having the first block size in the second frequency domain into smaller block sizes, thereby producing smaller block-sized random key stream of the second frequency domain; and converting the text using the smaller block-sized random key stream of the second frequency domain to produce the converted text. The frequency in the first frequency domain is preferably lower than the frequency in the second frequency domain.Type: GrantFiled: March 5, 2015Date of Patent: February 16, 2016Inventors: Michael James Lewis, Neil Leckett, A.

Patent number: 9008313Abstract: A system for generating random key stream cipher texts passes an unencrypted random key stream through an AES engine to produce encrypted cipher text having a first block size in a first frequency domain; converts the encrypted cipher text in the first frequency domain to encrypted cipher text in a second frequency domain; and converts the encrypted cipher text having the first block size in the second frequency domain into smaller block sizes. The frequency in the first frequency domain is preferably lower than the frequency in the second frequency domain. The converting of the encrypted cipher text in the first frequency domain to encrypted cipher text in a second frequency domain may be effected by a dual clock domain FIFO.Type: GrantFiled: July 24, 2014Date of Patent: April 14, 2015Assignee: Elliptic Technologies Inc.Inventors: Michael James Lewis, Neil Leckett, A.
