Meet PocketBlock, the crypto engineering game for kids of all ages

When you’re a cryptographer, telling your preteen kids what you do isn’t easy.

When you're an applied cryptographer, teaching your preteen daughters what you do for a living isn't easy. That's why Justin Troutman developed PocketBlock, a visual, gamified curriculum that makes cryptographic engineering fun.

In its current form, PocketBlock is a series of board-like grids that allow players to transform plaintext messages into secret ciphertext and convert it back again, one move at a time. By restricting the operations to little more than addition and subtraction performed by rearranging squares on a piece of paper, PocketBlock helps students understand the fundamentals of encryption without requiring a formal background in mathematics. At the same time, it stays true to the principles of modern cryptography and goes well beyond the classical cryptographic concepts, like the Caesar cipher, reserved for most kid-centric material on cryptography today.

"The goal is for kids to feel like they've worked with something of substance, to an extent that intrigues them," Troutman, a trained cryptographer who is currently the Project Manager at the Freedom of the Press Foundation, told Ars. "[PocketBlock] introduces cryptography as everything from a pillar of the modern Web to the tradecraft of spies past. It introduces the same cryptographic concepts that I work with as a cryptographer in industry—the same underpinnings you'll find in academic papers. It reduces these concepts to easy-to-solve problems and uses a visual language to map what happens to bits as they travel through a cryptographic algorithm."

Festnetz: Verbände sehen Kupfertechnologie am Ende

Die Konkurrenten der Telekom sehen die Kupfernetze am Ende, was Ping-Zahlen und Latenzzeiten anbelangt. Es sei Zeit, längerfristig zu denken und Glasfaser auszubauen. Bei der Fördermittelvergabe herrscht die Furcht, dass die Telekom fast alles kassiert. (Glasfaser, Breko)

Anti-Piracy Groups Petition Clinton & Trump for Tough Copyright Laws

Two leading anti-piracy groups have penned an open letter and Change.org petition calling on Clinton and Trump to adopt a tough approach to copyright law. Copyright Alliance and CreativeFuture, which count dozens of major studios and record labels among their members, say that protecting content is vital, no matter which party is in power.

trump-clintonAs the presidential election moves towards the home straight, millions of individuals and businesses in the United States are considering how the outcome might affect them.

Unsurprisingly, powerful groups in the entertainment industry are also weighing the implications and with billions at stake, who could blame them.

Of course, just like the rest of the population, neither Hollywood nor the major recording labels have a crystal ball, so in recent months their public lobbying efforts have been mindful of the possibility that either Clinton or Trump could get into power.

This week that trend continued, with the publication of a new open letter and the launch of a petition by two influential anti-piracy groups, the Copyright Alliance and CreativeFuture.

The Copyright Alliance is a true powerhouse which counts the MPAA, RIAA, Viacom, Oracle, Getty Images and many other corporations among its members. CreativeFuture is a huge coalition of some 450 companies in the film, television, music, and book publishing sectors.

In their letter addressed to “2016 Political Candidates”, the groups describe themselves as members of the creative community, who despite political differences are united in their goal of reducing piracy.

“While our political views are diverse, as creators, there are core principles on which we can all agree. And we appreciate the opportunity to share our views with our country’s current and future leaders,” the groups write.

What immediately becomes apparent in the letter are the glowing references to the Internet. With lessons learned from the SOPA debacle which was perceived by many as an attack on the world’s most important network, Copyright Alliance and CreativeFuture begin by cheerfully praising its positives.

“We embrace the internet as a powerful democratizing force for our world and for creative industries. We recognize its ability to inspire positive change and improve lives,” they write.

“In our creative industries, the internet has helped to advance creativity by removing barriers to entry for newcomers, fostering a dialogue with fans, audiences, and consumers, and providing numerous additional ways to reach them. The internet holds great potential to expand creativity and free expression.”

While one might have strongly expected a ‘but’ at this juncture, the groups are careful not to set up a clash of ideals. It’s not difficult to see that their aim is to quietly assure that the successful protection of copyrighted content does not have to come at the expense of the Internet.

“We embrace a strong copyright system that rewards creativity and promotes a healthy creative economy. The incredible cultural and economic value that the internet delivers to billions of users is based in very large part on the efforts of creative content makers whose livelihoods depend on being compensated for their efforts,” they add.

“Copyright should protect creators from those who would use the internet to undermine creativity. The internet can be a great tool for creators just as it can be a tool for science, education, health care, and many other disciplines. However, when misused, it can harm creativity and stifle freedom of expression.”

And if anyone missed the hints that Copyright Alliance and CreativeFuture are supporters of both creative content and the interests of the Internet, the groups quickly take the opportunity to underline that again. However, one gets the impression that their definition of online freedom might not be the same as that championed by Internet activists.

“Our current and future leaders recognize that a safe and secure internet benefits us all. And all parties recognize the importance of strong copyright protections in their technology policy platforms because protecting copyright and internet freedom are both critically important and complementary — they are not mutually exclusive,” they write.

“A truly free internet, like any truly free community, is one where people respect the rights of others and can engage in legitimate activities safely — and where those who do not are held accountable under law by their peers.”

Interestingly, the letter also warns 2016’s political candidates against “organizations and advocates” funded by “online platforms” that claim to be “pro-creators and pro-audience to mask their own self-serving agenda.”

These groups are not mentioned by name but the likes of EFF and Fight for the Future have been spoken of in similar terms and have appeared in negative articles published by the Copyright Alliance earlier this year.

“[The nameless groups] denigrate or block effective efforts to preserve and promote creative content, including enforcement of existing laws and voluntary industry initiatives,” Copyright Alliance and CreativeFuture warn, adding:

“The creative community is rightfully wary of any company or organization that claims to be ‘against piracy’ when their actions do not match their words.”

And of course, even if not mentioned by name, no appeal would be complete without a subtle reference to Google and/or YouTube. Trump and Clinton are left to fill in the gaps and asked to do the right thing.

“Internet platforms are making massive profits from creative contributions to the internet’s growth. It is not too much to ask that content creators should be able to share in the value they provide,” the groups write.

With the election likely to go to the wire, Copyright Alliance and CreativeFuture are keen to ensure that anti-piracy measures are seen as a universal concern, no matter where people reside on the political spectrum.

“There is no ‘left’ or ‘right’ when it comes to respecting copyright. The creative community stands united in support of a copyright system that will continue to make the United States the global leader in the creative arts and the global paradigm for free expression,” they note.

“Our copyright system is not perfect but, like democracy, it is better than the alternatives. It works. We urge our leaders to maintain America’s commitment to the right of creators to determine when and how they share their works in the global marketplace.”

In support of their open letter, Copyright Alliance and CreativeFuture have also launched a Change.org petition in an attempt to get 5,000 signatures supporting their cause.

“Whether you are a Democrat or Republican, liberal or conservative or libertarian, strong and effective copyright is not a partisan issue but rather one that benefits our entire country. We ask that you stand with us by adding your name to this letter – to show political candidates that we stand united, we stand creative,” they conclude.
