When SpaceX launched the world’s biggest rocket ship on Feb. 6, that kind of seemed like a big deal — but not everyone is impressed.

Previewing the SpaceX Falcon Heavy launch, The Wall Street Journal seemed perplexed. Yes, the Falcon Heavy is big, admitted the Journal. But as a “heavy-lift booster,” it said, it is a product designed to serve a market that’s suffering “significantly eroded commercial demand” and “uncertain commercial prospects.”

The problem, as the Journal (correctly) pointed out, is that thanks to advances in rocketry, electronics, and materials technology, “both national security and corporate satellites continue to get smaller and lighter” (and cheaper).

Networks that harness entanglement and teleportation could enable leaps in security, computing and science.

Howdy folks.

I hope you’ll find today’s post as interesting as I do. It’s a bit of brain candy and outlines an exciting vision for the future of digital identities.

Over the last 12 months we’ve invested in incubating a set of ideas for using Blockchain (and other distributed ledger technologies) to create new types of digital identities, identities designed from the ground up to enhance personal privacy, security and control. We’re pretty excited by what we’ve learned and by the new partnerships we’ve formed in the process. Today we’re taking the opportunity to share our thinking and direction with you. This blog is part of a series and follows on Peggy Johnson’s blog post announcing that Microsoft has joined the ID2020 initiative. If you haven’t already Peggy’s post, I would recommend reading it first.

WASHINGTON — It should be no surprise that China is moving to challenge the United States for dominance in space, cyber, artificial intelligence and other key technologies that have wide national security applications. But the question that is still being debated is whether the United States is taking this threat seriously.

This may not be a Sputnik moment, but the United States could soon be unpleasantly surprised as China continues to shore up its domestic capacity to produce high-end weapons, satellites and encryption technologies, a panel of analysts told the House Armed Services emerging threats and capabilities subcommittee.

At the Tuesday hearing, Subcommittee Chairman Rep. Elise Stefanik, R-N.Y., said lawmakers are not entirely convinced that China’s dominance in many technology sectors is a “foregone conclusion.” But the committee does believe that China’s technological accomplishments should inform U.S. policies and defense investments.

Ledger SAS, a startup that makes electronic wallets for Bitcoin and other cryptocurrencies, has raised 61 million euros ($75 million) from investors including Draper Esprit Plc.

A joint China-Austria team has performed quantum key distribution between the quantum-science satellite Micius and multiple ground stations located in Xinglong (near Beijing), Nanshan (near Urumqi), and Graz (near Vienna). Such experiments demonstrate the secure satellite-to-ground exchange of cryptographic keys during the passage of the satellite Micius over a ground station. Using Micius as a trusted relay, a secret key was created between China and Europe at locations separated up to 7,600 km on the Earth.

Private and secure communications are fundamental for Internet use and e-commerce, and it is important to establish a secure network with global protection of data. Traditional public key cryptography usually relies on the computational intractability of certain mathematical functions. In contrast, quantum key distribution (QKD) uses individual light quanta (single photons) in quantum superposition states to guarantee unconditional security between distant parties. Previously, the quantum communication distance has been limited to a few hundred kilometers due to optical channel losses of fibers or terrestrial free space. A promising solution to this problem exploits satellite and space-based links, which can conveniently connect two remote points on the Earth with greatly reduced channel loss, as most of the photons’ propagation path is through empty space with negligible loss and decoherence.

A cross-disciplinary multi-institutional team of scientists from the Chinese Academy of Sciences, led by Professor Jian-Wei Pan, has spent more than 10 years developing a sophisticated satellite, Micius, dedicated to quantum science experiments, which was launched on August 2016 and orbits at an altitude of ~500 km. Five ground stations in China coordinate with the Micius satellite. These are located in Xinglong (near Beijing), Nanshan (near Urumqi), Delingha (37°22’44.43’‘N, 97°43’37.01” E), Lijiang (26°41’38.15’‘N, 100°1’45.55’‘E), and Ngari in Tibet (32°19’30.07’‘N, 80°1’34.18’‘E).

WiFi security hasn’t changed much since WPA2 came to be in 2004, and that’s becoming increasingly apparent when public hotspots are frequently risky and glaring exploits are all too common. It’s about to get a long-due upgrade, though: the Wi-Fi Alliance plans to roll out a WPA3 standard that addresses a number of weak points. For many, the highlight will be individualized data encryption. Even if you’re on an open public network, you won’t have to worry quite so much about someone snooping on your data.

You’ll also see safeguards even when people have terrible passwords, and a simplified security process for devices that have either a tiny display or none at all (say, wearable devices or smart home gadgets). And companies or governments that need stricter security will have access to a 192-bit security suite.

WPA3 should arrive sometime in 2018, and comes on the back of other improvements like more thorough testing to catch potential vulnerabilities before they require emergency patches. These initiatives aren’t going to guarantee airtight security when you’re at the coffee shop, but they could at least eliminate some of WiFi’s more worrying flaws.
