Google launches OpenTitan, an open-source secure chip design project

Eric L. Hannon



Although there are many ways to infect applications on a computer, ours, cybersecurity, is about firmware and chips. Google wants to make sure everyone can create a trusted root at the chip level with their Open Titan project. This project aims to establish an open common reference design.


This allows many people to improve the original design and increase the security of implementation.

Google announced that it has partnered with a number of nonprofit companies and organizations to launch a new initiative called OpenTitan. The goal is to develop a secure open source chip design for data centers and infrastructures. These designs can be examined and developed independently.

The project is named after the Google Titan chip, used in its datacenters and pixel phones, confirming the launch of a known trust status and ensuring that the firmware has not been tampered with.

The cryptographic element used for verification is called the root of trust (RoT) and is at the heart of the OpenTitan project.

According to Google, OpenTitan is operated by the non-profit association LowRisc, which is supported by other partners. These partners include ETH Zurich, Nuvoton Technology, G + D Mobile Security and Western Digital. However, the project’s open source concept ensures that it is platform-independent and can be adapted to any device.

The basic principle of RoT is that the software can be run on components considered safe with “authorized and verifiable code”. According to the Google blog, the benefits of silicon RoT include:

Make sure the devices are booted with the correct firmware without being infected with malware.
Provide a cryptographically unique computer identity so that an operator can verify that a server or device is legitimate.

Protect secrets such as tamper-resistant encryption keys, even for people with physical access (for example, when delivering a server or device).

Provide infallible, authoritative monitoring records and other security services at run time.

The company hopes to increase confidence and security by promoting transparency through open source silicon design, while fostering innovation. Problems can be resolved quickly and implementations can use common interfaces through an open reference design.

Apple uses its own RoT chip, called T2, in many of its devices. Samsung implements a version of Secure Boot on its Knox platform, while many Windows PCs also implement Secure Boot.

While some of Google’s motives are skeptical, the overall goal of the OpenTitan project seems to be accommodating and hopefully encourages chip makers and platform designers to more easily integrate the RoT into their designs.

Instagram is testing a new video editing tool that sounds a lot like TikTok

Eric L. Hannon



It was only a matter of time before the Facebook cloning machine came online to counter the growing threat of the TikTok viral video application.

It seems that Facebook’s own Instagram wants to copy some of the features of TikTok. Developers are developing a new application-integrated video editing tool that allows users to add AR effects and background music to clips, adjust their speed and even remix other videos – a feature included in the feature “duo” of TikTok. is very similar. The tool is called so-called “scenes”.

The information comes from Jane Manchun Wong, a software developer who has made a name for herself as a programmer in reverse engineering the best applications to discover new features. You can see his tweet on the subject below:

There is no guarantee that “Scenes” will definitely be launched by Instagram, but Wong has a good track record of looking for new features in the app. She discovered Instagram’s mute a month before the official announcement and ran tests in April to hide Likes, a feature that needed to be tested to verify its authenticity in seven countries. Wong says that “Scenes” is in itself a remix of a new feature called “Clips”.

We also know that Facebook is very interested in fighting the rise of TikTok. The company had already launched a limited product for a TikTok self-contained clone called Lasso, and when Mark Zuckerberg spoke with the staff, Le Verge said that Instagram might need to be convinced to fight this newcomer.

TikTok “married a short immersive video with Browse,” said Zuckerberg. “It’s almost like the Explore tab we have on Instagram.”

The time has come for TikTok’s competitors to collapse (Google would also work on its own counters). The application has experienced considerable growth, but faces regulatory issues, including a US national security clearance. Time flies.

Here’s why Netflix is ditching old Roku devices: DRM

Charles M. Poole



Last week, Netflix announced that support for older Samsung, Roku and Vizio devices will cease after December 1st.

However, the reason why these devices are losing their support is unclear, aside from the fact that they are obsolete. A Netflix help document is not useful because the problem is due to “technical limitations”.

However, Netflix has provided some details about these technical limitations of older Roku devices with Gizmodo, and the answer is very simple: digital rights management.

Here’s what happens: Netflix has been using Microsoft’s PlayReady DRM software since 2010, making it easy to streamline its streaming service on a variety of TVs, devices, and set-top boxes that you can find today and at the same time.

Content providers who are not eligible for their work will not be hacked. Since Netflix had already shipped devices such as the affected Rokus with an outdated form of outdated Windows Media DRM, they would inevitably be left behind if Netflix ever breaks the connection to the old DRM standard and these devices can not be set to level towards the new PlayReady. Now, and they can not.

Gizmodo’s article does not explain why older Samsung and Vizio devices can not use Netflix, but we would not be surprised if this is the same reason. We asked Netflix if that was the case.

Google Stadia’s 12-game launch lineup is surprisingly weak

Catherine A. Leal



Although Google Stadia is hailed as the future of the game – a future that does not require expensive consoles or regular computer upgrades to stay up to date with video game technology – the recently announced launch of the game. Streaming game platform is surprisingly weak. Offer

Of the 12 titles offered at the launch of Google Stadia on November 19, 2019, only a fraction of it can be considered particularly difficult for most gaming computers and some titles are a year or more.

  • Assassin’s Creed Odyssey
  • Destiny 2: The Collection
  • GYLT
  • Just Dance 2020
  • Kine
  • Mortal Kombat 11
  • Red Dead Redemption 2
  • Thumper
  • Tomb Raider: Definitive Edition
  • Rise of the Tomb Raider
  • Shadow of the Tomb Raider: Definitive Edition
  • Samurai Shodown

as you can see in the list above, only a few new titles were published this year by Google Stadium (Tomb Raider: Definitive Edition released in 2014), which seriously undermines one of the main selling points of the platform. cloud gameform: its ability to do it. Play the latest games right away with 4K, 60fps and Ultra resolution.

In other words, if there is a beacon in the lineup, it is the Red Dead Redemption 2 that has just been released on PC and is supposed to require a powerful game board for decent performance. .

Fortunately, more games will appear on Google Stadia in the coming months. The search giant announces a series of titles to be released in the remainder of 2019.

These include titles such as “Attack on Titan 2: Final Battle”, “Borderlands 3”, “Darksiders: Genesis”, “Dragon Ball Xenoverse 2”, “Farming Simulator 19”, “Final Fantasy XV”, “Ghost Breakpoint Recon “, Grid, Metro Exodus, NBA 2K 2020, Rage 2 and Trials Rising and Wolfenstein Youngblood.

While it’s good to see a major new release on the way to service like Borderlands 3, the absence of other major releases of 2019, such as Call of Duty: Modern Warfare and Star Wars Jedi: Fallen Order, is certainly disappointing.

It is hoped that the release of the games will be faster when the Stadia platform is established.
