The quantum meltdown of encryption

The world stands at the cusp of one of the greatest breakthroughs in information technology. Huge leaps forward in all fields of computer science, from data analysis to machine learning, will result from this breakthrough. But like all of man’s technological achievements, from the combustion engine to nuclear power, harnessing quantum comes with potential dangers as well. Quantum computers have created a slew of unforeseen vulnerabilities in the very infrastructure that keeps the digital sphere safe.

The underlying assumption behind nearly all encryption ciphers used today is that their complexity precludes any attempt by hackers to break them, as it would take years for even our most advanced conventional computers to do so. But quantum computing will change all of that.

Quantum computers promise to bring computational power leaps and bounds ahead of our most advanced machines. Recently, scientists at Google began testing their cutting edge 72 qubit quantum computer. The researchers expect to demonstrate with this machine quantum supremacy, or the ability to perform a calculation impossible with traditional computers.

Chink in the Armor

Today’s standard encryption techniques are based on what’s called Public Key Infrastructure or PKI, a set of protocols brought to the world of information technology in the 1970’s. PKI works by generating a complex cipher through random numbers that only the intended recipient of a given message, the one in possession of the private key, can decode.

As a system of encoding data, PKI was sound and reliable. But in order to implement it as a method to be used in the real world, there was still one question that needed to be answered: how could individuals confirm the identity of a party reaching out and making a request to communicate? This vulnerability left the door open for cybercriminals to impersonate legitimate servers, or worse, insert themselves into a conversation between users and intercept communications between them, in what’s known as a Man-in-the-Middle (MITM) attack.

The industry produced a solution to this authentication problem in the form of digital certificates, electronic documents the contents of which can prove senders are actually who they claim to be. The submission of certificates at the initiation of a session allows the parties to know who it is they are about to communicate with. Today, trusted third party companies called Certificate Authorities, or CAs, create and provide these documents that are relied upon by everyone from private users to the biggest names in tech.

The problem is that certificates themselves rely on public-key cryptographic functions for their reliability, which, in the not too distant future, will be vulnerable to attack by quantum machines. Altered certificates could then be used by cyber criminals to fake their identities, completely undermining certificates as a method of authentication.

Decentralizing the Threat

This isn’t the first time we’ve had to get creative when it comes to encryption.

When Bitcoin creator Satoshi Nakamoto, whose true identity is still unknown, revealed his revolutionary idea in a 2008 white paper, he also introduced the beginnings of a unique peer-to-peer authentication system that today we call blockchain. The brilliantly innovative blockchain system at its core is an open ledger that records transactions between two parties in a permanent way without needing third-party authentication. Blockchain provided the global record-keeping network that has kept Nakamoto’s digital currency safe from fraudsters. Blockchain is based on the concept of decentralization, spreading the authentication process across a large body of users. No single piece of data can be altered without the alteration of all other blocks, which would require the collusion of the majority of the entire network.

For years, blockchain and Bitcoin remained one and the same. About five years ago, innovators in the industry began to realize that blockchain could be used for more than just securing cryptocurrency. Altering the original system designed for Bitcoin could produce programs to be applied in a wide range of industries, from healthcare, to insurance, to political elections. Gradually, new decentralized systems began to emerge such as those of Ripple and Litecoin. In 2015, one of the original contributors to the Bitcoin codebase Vitalik Buterin released his Ethereum project also based on blockchain. What these new platforms added to the picture was the ability to record new types of data in addition to currency exchanges, such as loans and contractual agreements.

The advantages of the blockchain concept quickly became apparent. By 2017, nearly fifteen percent of all financial institutions in the world were using blockchain to secure aspects of their operations. The number of industries incorporating decentralized systems continues to grow.

Saving PKI

The best solution for protecting encryption from our ever-growing processing power is integrating decentralization into Public Key Infrastructure.

What this means essentially, is that instead of keeping digital certificates in one centralized location, which makes them vulnerable to being hacked and tampered with, they would be spread out in a world-wide ledger, one fundamentally impervious to alteration. A hacker attempting to modify certificates would be unable to pull off such a fraud, as it would mean changing data stored on enumerable diversified blocks spread out across the cyber sphere.

Decentralization has already been proven as a highly effective way of protecting recorded data from tampering. Similarly, using a blockchain-type system to replace the single entity Certificate Authority, can keep our digital certificates much safer. It is in fact one of the only foreseeable solutions to keep the quantum revolution from undermining the foundation of PKI.

Propelling deep space flight with a new fuel source, Momentus prepares for liftoff

Mikhail Kokorich, the founder of Momentus, a new Y Combinator-backed propulsion technology developer for space flight, hadn’t always dreamed of going to the moon.

A physicist who graduated from Russia’s top-ranked Novosibirsk University, Kokorich was a serial entrepreneur in who grew up in Siberia and made his name and his first fortunes in the years after the fall of the Soviet Union.

The heart of Momentus’ technology is a new propulsion system that uses water as a propellant instead of chemicals.

Using water has several benefits, Kokorich says. One, it’s a fuel source that’s abundant in outer space, and it’s ultimately better and more efficient fuel for flight beyond low earth orbit. “If you move something with a chemical booster stage to the moon. Chemical propulsion is good when you need to have a very high thrust,” according to Kokorich. Once a ship gets beyond gravity’s pull, water simply works better, he says.

Some companies are trying to guide micro-satellites with technologies like Phase 4 which use ionized gases like Xenon, but according to Kokorich those are more expensive and slower. “When ionized propulsion is used for geostationary satellites to orbit, it takes months,” says Kokorich, using water can half the time.

“We can carry ten tons to geostationary orbit and it’s much faster,” says Kokorich.

The company has already signed an agreement with ECM Space, a European launch services provider, which will provide the initial trip for the company’s first test of its propulsion system on a micro-satellite — slated for early 2019.

That first product, “Zeal,” has specific impulses of 150 to 180 seconds and power up to 30 watts.

Kokorich started his first business, Dauria, in the mid-90s amid the collapse of the Soviet Union, selling explosives and engineering services to mining companies in Siberia. Kokorich sold that business and went into retail, eventually building a network of stores that sold home goods and housewares across Russia.

That raked in more millions for Kokorich, who then said he diversified into electronics by buying Russia’s BestBuy chain out bankruptcy. But space was never far from his mind, and, eventually he returned to it.

“In 2011 I hit my middle-aged crisis,” Korkorich says. “So I founded the first private Russian aerospace company.”

That company, Dauria Aerospace, was initially feted by the government, garnering the entrepreneur a place in Skolkovo, and its inaugural cohort of space companies. In an announcement of the successes the space program had achieved in 2014 Kokorich co-authored a piece with the Russian cosmonaut Sergey Zhukov, who remains the executive director of the networking and aerospace programs at the multi-billion-dollar boondoggle startup incubator.

A few months later Kokorich would be in the U.S. working to back the first of what’s now a triumvirate of startups focused on space.

“With all the problems with Russia in the Western world, I moved to the U.S.,” says Kokorich. Dauria had quickly raised $30 million for its work, but as this Moscow Times article notes, stiff competition from U.S. firms and the sanctions leveled against Russia in the wake of its invasion and annexation of Crimea were taking their toll on the entrepreneur’s business. “It was a purely political immigration,” Korkorich says. “I don’t have purely business opportunities, because you have to work with the government [and] because the government would not like me.”

For all of his protestations, Kokorich has maintained several economic ties with partners in Russia. It’s through an investment firm called Oden Holdings Ltd. that Kokorich took an investment stake in the Canadian company Helios Wire, which was one of his first forays into space entrepreneurship outside of Russia. That company makes cryptographically secured applications for the transmission and reception of data from internet-enabled devices.

The second space company that the co-founder has built since moving to the U.S. is the satellite company Astra Digital, which processes data from satellites to make that information more accessible.

Now, with Momentus, Kokorich is turning to the problem of propulsion. “When transportation costs decrease, many business models emerge” Kokorich says. And Kokorich sees Momentus’ propulsion technology driving down the costs of traveling further into space — opening up opportunities for new businesses like asteroid mining and lunar transit.

The Momentus team is already thinking well beyond the initial launch. The company’s eyes are on a prize well beyond geostationary orbit.

Indeed, with water as a power source, the company says it will lay the groundwork for future cislunar and interplanetary rides. The company envisions a future where it will power water prospecting and delivery throughout the solar system, solar power stations, in-space manufacturing and space tourism.
