Email was one of the earliest forms of communication on the internet, and if you’re reading this you almost undoubtedly have at least one email address. Critics today decry the eventual fall of email, but for now it’s still one of the most universal means of communicating with other people that we have. One of the biggest problems with this cornerstone of electronic communication is that it isn’t very private. By default, most email providers do not provide the means to encrypt messages or attachments. This leaves email users susceptible to hackers, snoops, and thieves.

So you want to start encrypting your email? Well, let’s start by saying that setting up email encryption yourself is not the most convenient process. You don’t need a degree in cryptography or anything, but it will take a dash of tech savvy. We’ll walk you through the process later on in this article.

Alternatively, you can use an off-the-shelf encrypted email client. Tutanota is one such secure email service, with apps for mobile and a web mail client. It even encrypts your attachments and contact lists. Tutanota is open-source, so it can be audited by third parties to ensure it’s safe. All encryption takes place in the background. While we can vouch for Tutanota, it’s worth mentioning that there are a lot of email apps out there that claim to offer end-to-end encryption, but many contain security vulnerabilities and other shortcomings. Do your research before choosing an off-the-shelf secure email app.

If you’d prefer to configure your own email encryption, keep reading.

Google has not had any of its 85,000+ employees successfully phished on their work-related accounts since early 2017, when it began requiring all employees to use physical Security Keys in place of passwords and one-time codes, the company told KrebsOnSecurity.

Security Keys are inexpensive USB-based devices that offer an alternative approach to two-factor authentication (2FA), which requires the user to log in to a Web site using something they know (the password) and something they have (e.g., a mobile device).

The US Department of Justice (DOJ) this week released the first report from its Cyber Digital Task Force – which was set up in February to advise the government on strengthening its online defenses.
The report [PDF], compiled by 34 people from six different government agencies, examines the challenges facing Uncle Sam´s agencies in enforcing the law and protecting the public from hackers. It also lays out what the government needs to do to thwart looming threats to its computer networks.

Let´s (not) Encrypt

If you´ve been following the news for the last few years it will come as no surprise that the Justice Department is not a fan of the common man having access to encryption.
The report bemoans the current state of encryption and its ability to keep the government from gathering and analyzing traffic for criminal investigations. The word ´encryption´ comes up 17 times in the report, not once in a favorable light.
In the past several years, the Department has seen the proliferation of default encryption where the only person who can access the unencrypted information is the end user, the report reads.
The advent of such widespread and increasingly sophisticated encryption technologies that prevent lawful access poses a significant impediment to the investigation of most types of criminal activity.

The demand for quantum computing services will be driven by some process hungry research and development projects as well as by the emergence of several applications including advanced artificial intelligence algorithms, next-generation encryption, traffic routing and scheduling, protein synthesis, and/or the design of advanced chemicals and materials. These applications require a new processing paradigm that classical computers, bound by Moore’s law, cannot cope with. However, one should not expect quantum computers to displace their classical counterparts anytime soon.

Ray Ozzie thinks he has an approach for accessing encrypted devices that attains the impossible: It satisfies both law enforcement and privacy purists. (?)

EFAIL furore not over yet, even though it´s easy to fix.

However, PGP´s creator Phil Zimmerman, Protonmail´s Any Yenn, Enigmail´s Patrick Brunschwig, and Mailvelope´s Thomas Oberndörfer are still concerned that misinformation about the bug remains in the wild.

Yenn tried to refute the EFAIL “don´t use PGP” on May 25, and the four have followed up with this joint post.

According to a Venafi survey of 512 security professionals attending RSA Conference 2018, sixty-four percent of respondents say their personal encryption usage has increased due to recent geopolitical changes.

Encryption is making it more difficult for law enforcement agencies to detect dangerous offenders, according the the National Crime Agency's (NCA) yearly assessment of serious organised crime in Britain.

Since 2010, communication service providers have migrated to encrypted services ´by default´, a process that accelerated following the Snowden disclosures, said the National Strategic Assessment of Serious and Organised Crime 2018

US lawmakers from both major political parties came together on Thursday to reintroduce a bill that, if passed, would prohibit the American government from forcing tech product makers to undermine the security of their wares.

Spoiler alert: this article explains a key plot point, but we don’t give away anything you won’t see in trailers. Thanks to reader Florence, 7, for her questions.

At the beginning of the new Disney Pixar film, Lightyear, Buzz Lightyear gets stranded on a dangerous faraway planet with his commanding officer and crew.

Their only hope of getting off the planet is to test a special fuel. To do that, Buzz has to fly into space and repeatedly try to jump to hyper-speed. But each attempt he makes comes with a terrible cost.

Every time Buzz takes off for a four-minute test flight into space, he lands back on the planet to find many years have passed. The people Buzz cares most about fall in love, have kids and even grandkids. Time becomes his biggest enemy.

What’s going on? Is this just science fiction, or could what happened to Buzz actually happen?

Time Is Relative: Einstein’s Big Idea

Buzz is experiencing a real phenomenon known as time dilation. Time dilation is a prediction of one of the most famous scientific theories ever developed: Albert Einstein’s theory of relativity.

Prior to relativity, the best theory of motion we had was Isaac Newton’s mechanics.

Newton’s theory was incredibly powerful, providing stunning predictions of the motion of the planets in our solar system.

In Newton’s theory, time is like a single giant clock that ticks away the seconds in the same way for everyone. No matter where you are in the universe, the master clock will display the same time.

Einstein’s theory of relativity shattered the master clock into many clocks—one for each person and object in motion. In Einstein’s picture of the universe, everyone carries their own clock with them.

One consequence of this is there is no guarantee the clocks will tick at the same rate. In fact, many clocks will tick at different rates.

Even worse, the faster you travel relative to someone else, the slower your clock will tick compared to theirs.

This means if you travel very fast in a spaceship—as Buzz does—a few minutes might pass for you, but years might pass for someone on the planet you left behind.

Time Traveling Forwards—but Not Backwards

In a sense, time dilation can be thought of as a kind of time travel. It provides a way to jump into someone else’s future.

This is what Buzz does: he jumps into the future of his friends left on the planet below.

Unfortunately, there is no way to use time dilation to travel backwards in time, into the past (as one important character talks about later in the film).

It’s also not possible to use time dilation to travel into your own future.

That means there’s no known way for you to travel into the future and meet your older self, simply by going really fast.

Time Travelers Above Earth Right Now

Time dilation might seem like science fiction, but in fact it is a measurable phenomenon. Indeed, scientists have conducted a number of experiments to confirm that clocks tick at different rates, depending on how they are moving.

For example, astronauts on the International Space Station are traveling at very high speeds compared with their friends and family on Earth. (You can watch the space station pass overhead if you know when to look up.)

This means those astronauts are aging at a slightly slower rate. Indeed, US astronaut Buzz Aldrin, from whom Buzz in Lightyear gets his name, would have experienced a tiny bit of time dilation during his trip to the Moon in the 1960s.

Don’t worry, though, the astronauts on the International Space Station won’t feel or notice any time dilation. It’s nothing like the extreme time jumps seen in Lightyear.

Aldrin was able to return safely to his family, and the astronauts up in space now will too.

To Infinity—and Beyond

Clearly, time dilation could have a serious cost. But it’s not all bad news. Time dilation could one day help us travel to the stars.

The universe is a massive place. The nearest star is 40,208,000,000,000 km away. Getting there is like traveling around the world one billion times. Traveling at an ordinary speed, no one would ever survive long enough to make the trip.

Time dilation, however, is also accompanied by another phenomenon: length contraction. When one travels very fast toward an object, the distance between your spaceship and that object will appear to be contracted.

Very roughly, at high speeds, everything is closer together. This means that for someone traveling at a high speed, they could make it to the nearest star in a matter of days.

But time dilation would still be in effect. Your clock would slow relative to the clock of someone on Earth. So, you could make a round trip to the nearest star in a few days, but by the time you arrived home everyone you know would be gone.

That is both the promise, and the tragedy, of interstellar travel.
