Researchers from the Ruhr University of Bochum’s Secure Hardware Group in Germany have cracked the copy protection system used by HDMI ports: Intel’s HDCP, or High-bandwidth Digital Content Protection. In addition to HDMI, HDCP is used to encrypt video signals transferred via DVI, DisplayPort and other connectors.
“In 2010, an HDCP master key, which is intended to form the secret core element of the encryption system, appeared briefly on a website,” reads the official press release. “In response, the manufacturer Intel announced that HDCP still represented an effective protection component for digital entertainment, as the production of an HDCP-compatible chip using this master key would be highly complex and expensive.”
Seemingly taking that as a challenge, the team accomplished the “inexpensive” man-in-the-middle attack by using Digilent’s Atlys Spartan-6 FPGA development board. It features a Xilinx Spartan-6 LX45 FPGA (field programmable gate array) in a 324-pin BGA package, two HDMI video input ports, two HDMI video output ports, a 10/100/1000 Ethernet jack, a RS232 serial port and more.
As 2022 starts, let’s take some time to share our goals for CircuitPython in 2022. Just like past years (full summary 2019, 2020, and 2021), we’d like everyone in the CircuitPython community to contribute by posting their thoughts to some public place on the Internet. Here are a few ways to post: a video on YouTub, a post on the CircuitPython forum, a blog post on your site, a series of Tweets, a Gist on GitHub. We want to hear from you. When you post, please add #CircuitPython2022 and email firstname.lastname@example.org to let us know about your post so we can blog it up here.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
