Crypto guru Matt Green asks courts for DMCA force field so he can safely write a textbook

Next move in EFF's plans to regain the right to tinker


Assistant Professor Matthew Green has asked US courts for protection so that he can write a textbook explaining cryptography without getting sued under the Digital Millennium Copyright Act.

Green, who teaches at Johns Hopkins University in Maryland, is penning a tome called Practical Cryptographic Engineering that examines the cryptographic mechanisms behind the devices we use every day, such as ATM machines, smart cars, and medical devices. But this could lead to a jail sentence if the manufacturers file a court case using Section 1201 of the DMCA.

Section 1201 prohibits the circumvention of copyright protection systems installed by manufacturers, and comes with penalties including heavy fines and possible jail time. As such, the Electronic Frontier Foundation (EFF) has taken up Green’s case, and that of another researcher, to try to get the provision ruled illegal by the courts.

“If we want our communications and devices to be secure, we need to protect independent security researchers like Dr Green,” said EFF staff attorney Kit Walsh.

“Researchers should be encouraged to educate the public and the next generation of computer scientists. Instead, they are threatened by an unconstitutional law that has come unmoored from its original purpose of addressing copyright infringement. We’re going to court to protect everyone whose speech is squelched by this law, starting with Dr Green and his book.”

The US Department of Justice has asked the courts to dismiss the case on the grounds that it is highly unlikely that Green would be prosecuted. They are possibly right, but that’s not the point of this lawsuit – the real goal is the destruction of the DMCA.

As Cory Doctorow explained at last year’s DEF CON, supporters of the DMCA are smart about what cases they choose to prosecute. The first test case was brought against 2600, The Hacker Quarterly, after it published the DeCSS code.

DeCSS allowed anyone to circumvent the copy protection systems built into commercial DVDs. Doctorow opined that the case went ahead because the entertainment companies knew it would be a slam dunk – the magazine had limited funds and the court would be protested by ugly-looking hackers.

By contrast, the Recording Industry Association of America backed down in its lawsuit against Princeton professor Edward Felten over his cracking of the Secure Digital Music Initiative, a watermarking system for CDs. Felten was due to present a paper on the technology and was promptly sued, but the RIAA dropped its case, in part due to worries that a jury wouldn’t stomach censoring an academic.

So the EFF has decided to support two actions against the DMCA: Green and the case of researcher Andrew Huang, who wants to make an open-source computer that would allow commercial videos to be edited. EFF is hoping that these test cases can bring down Section 1201, and hopefully the entire DMCA. ®

  • Biden considers removal of Trump-era China tariffs to ease inflation
    But US administration split on loss of leverage, according to reports

    US president Joe Biden is debating whether to end or cut Trump-era tariffs imposed on Chinese imports into the United States, according to reports.

    Introduced in 2018 during the Trump administration, tariffs on more than $300 billion in imports from China — including products and components vital in consumer and business technologies — were inherited by the Biden administration.

    According to Bloomberg, president Biden and his cabinet have discussed the inflationary impact of these levies with Treasury Secretary Janet Yellen. The cabinet was looking at all of the possible ways to curb inflation and to provide some relief on cost of living for Americans, the report said.

  • Semiconductor market to be hit by fresh wave of rising component costs
    Chemicals supplier warns it expects to raise prices, may cut some product lines

    More red flags about the semiconductor market are being raised with the news that a key supplier to chipmakers such as TSMC is planning to hike prices, which will likely have a knock-on effect on chip prices.

    Japan-based chemicals company Showa Denko has warned it expects to raise prices and may have to cut back some of its unprofitable product lines. The company is a major supplier of chemicals and gases that are used in the semiconductor manufacturing industry for the creation of silicon wafers and in the etching process to create chips.

    In an interview with Bloomberg, Showa Denko chief financial officer Hideki Somemiya said the company had already raised prices at least a dozen times this year, citing issues such as COVID-19 lockdowns, increasing energy costs and other factors. However, he confirmed "the current market moves require us to ask twice the amount we had previously calculated."

  • Germany unveils plan to tackle cyberattacks on satellites
    Vendors get checklist on what to do when crooks inevitably turn up in space

    The German Federal Office for Information Security (BSI) has put out an IT baseline protection profile for space infrastructure amid concerns that attackers could turn their gaze skywards.

    The document, published last week, is the result of a year of work by Airbus Defence and Space, the German Space Agency at the German Aerospace Center (DLR), and BSI, among others. It is focused on defining minimum requirements for cyber security for satellites and, a cynic might say, is a little late to the party considering how rapidly companies such as SpaceX are slinging spacecraft into orbit.

    The guide categorizes the protection requirements of various satellite missions from "Normal" to "Very High" with the goal of covering as many missions as possible. It is also intended to cover information security from manufacture through to operation of satellites.

  • Gtk 5 might drop X.11 support, says GNOME dev
    Linux's Wayland-only future takes a tentative step closer

    One of the GNOME developers has suggested that the next major release of Gtk could drop support for the X window system.

    Emmanuele Bassi opened a discussion last week on the GNOME project's Gitlab instance that asked whether the developers could drop X.11 support in the next release of Gtk.

    At this point, it is only a suggestion, but if it gets traction, this could significantly accelerate the move to the Wayland display server and the end of X.11.
