Alice and Bob are the world’s most famous cryptographic couple. Since their invention in 1978, they have at once been called “inseparable,” and have been the subject of numerous divorces, travels, and torments. In the ensuing years, other characters have joined their cryptographic family. There´s Eve, the passive and submissive eavesdropper, Mallory the malicious attacker, and Trent, trusted by all, just to name a few.

Draft blends asymmetric public/private key encryption and one-time pad analogs.
In case someone manages to make a general purpose quantum computer one day, a group of IETF authors have put forward a proposal to harden Internet key exchange.

While only an “informational” document at this stage, what the authors describe is how to extend Internet Key Exchange v2 (RFC 7296*, IKEv2) to support a quantum-safe key exchange.

Daniel J. Bernstein, Nadia Heninger, Paul Lou, and Luke Valenta: Post-Quantum RSA

Abstract: This paper proposes RSA parameters for which (1) key generation, encryption, decryption, signing, and verification are feasible on today´s computers while (2) all known attacks are infeasible, even assuming highly scalable quantum computers. As part of the performance analysis, this paper introduces a new algorithm to generate a batch of primes. As part of the attack analysis, this paper introduces a new quantum factorization algorithm that is often much faster than Shor´s algorithm and much faster than pre-quantum factorization algorithms. Initial pqRSA implementation results are provided.

A seamless, easy-to-use, and secure end-to-end encrypted business collaboration tool with no central point of attack is a holy grail for every business, and Boston-based security company PreVeil believes they have the right solution on hand.

Encrypted traffic accounts for a large and growing percentage of all network traffic. While the adoption of SSL, and its successor, Transport Layer Security (TLS), should be cause for celebration – as encryption improves confidentiality and message integrity – it also puts organizations at risk. This is because hackers can leverage encryption to conceal their exploits from security devices that do not inspect SSL traffic.

How serious is the threat? According to a recent Gartner survey, “less than 20% of organizations with a firewall, an intrusion prevention system (IPS) or a unified threat management (UTM) appliance decrypt inbound or outbound SSL traffic.”1 This means that hackers can evade over 80% of companies’ network defenses simply by tunneling attacks in encrypted traffic.

To stop cyber attacks, organizations must gain insight into encrypted data, and to do this, they need a dedicated security platform that can decrypt inbound and outbound SSL traffic.

The History and Mystery of the World´s Greatest Ciphers from Ancient Egypt to Online Secret Societies

Craig Bauer Princeton University Press: 2017.

A mystery inside an Enigma

The Enigma has a surprisingly understated design for being such a deadly tool. It could easily be mistaken for a typewriter with a few extra parts, housed in a plain wooden box.

The report covers the present scenario and the growth prospects of the global e-mail encryption market for the period 2016-2020. To calculate the market size, the report considers the revenues generated from e-mail encryption solutions provided to organizations including large organizations, small and medium-sized businesses (SMBs), and government organizations for encrypting business e-mails.

US, UK, Australia, New Zealand and Canada mull leaning hard for access to your info.

Officials from the United States, the United Kingdom, Canada, Australia and New Zealand will discuss next month plans to force tech companies to break encryption on their products.

The so-called Five Eyes nations have a long-standing agreement to gather and share intelligence from across the globe. They will meet in Canada with a focus on how to prevent \"terrorists and organized criminals\" from \"operating with impunity ungoverned digital spaces online,\" according to Australian prime minister Malcolm Turnbull.\"

NEWS ANALYSIS: Quantum computing's potential for cracking encryption worries the National Security Agency, so it is developing standards and strategies to support encryption in a post-quantum world.

After demonstrating how easily Apple’s Touch ID can be fooled with a user fingerprint photographed from a glass surface, Chaos Computer Club (CCC) hacker “Starbug” has proven that the iris recognition system in Samsung’s Galaxy S8 smartphone can be fooled by using a printed photo of the user’s eye(s).

Think about your favorite work of art. Why do you like it so much? What does it do for you?

Be it painting, sculpture, music, or writing, we love art not just for its beauty, but for the reactions and emotions it evokes in us. You probably feel a sort of kinship with your favorite artists even though you’ve never met them, because their work speaks to you in what feels like a unique and personal way.

How does this change when the art in question is produced by a machine and not a human? Is creativity an irreplaceable human skill, or will computers be able to learn it?

In a new video from Big Think, Andrew McAfee, associate director of MIT Sloan School of Management’s Center for Digital Business, discusses these questions and explores the concept of creative AI.

McAfee notes that as it stands, AI can mimic some forms of creativity and create art. Generative design, for example, lets you input specifications including materials, budget, and manufacturing methods into software, and it generates design alternatives. In many cases these alternatives look and perform better than human-conceived designs.

Robots can paint in the style of a master artist or their own style. Software can also compose music, and when people don’t know they’re listening to AI-generated music, they like it.

The standout feature of these computer-generated forms of art is that they require human inputs before they’re able to create something. Design software needs parameters to know what it’s working with, and music software needs code for the basic rules of music as a starting point.

Based on one of the definitions of creativity McAfee mentions—the ability to come up with something that’s valuable and also novel—this software technically qualifies as creative.

Luckily for us humans, though, McAfee offers a second, more profound definition of creativity: understanding the human condition, illuminating it, and reflecting it back to us in a way that we respond to.

While AIs can create original ‘works of art’ if we give them some guidance, they certainly don’t have any awareness of the fundamental conditions of being human, such as being aware of our own mortality, living inside a designated physical body, and probably most importantly, interacting with and relating to other humans.

McAfee calls our understanding of these the ‘native speaker’s intuition’ about the human condition, and though he’s a self-proclaimed technology optimist, he says, “I’m skeptical we’re going to be able to successfully convey that intuition even to… a really big, really sophisticated piece of technology. If that day ever comes, it’s a long way away.”

Creating a creative monster

But besides wondering whether AI will ever be able to understand the human condition and reflect it back to us in a meaningful way, shouldn’t we also be wondering why—or, better yet, whether—we want it to be able to?

We’ve already created AIs that can diagnose illness, drive cars, and win at Go. Siri can answer questions. Google Home and Amazon Echo and help run our homes smoothly.

As more tasks become automated—often with the result of those tasks being performed far more efficiently than we were performing them—more jobs will be lost. Optimists believe the shift created by technological unemployment will unleash the world’s creativity, allowing us to work less and devote more time and energy to our true passions—which for many people involve creative endeavors.

If this best-case scenario proves true and we end up with lots of time on our hands to create whatever our hearts desire, it seems like giving AI an understanding of the human condition would just be one more way to render ourselves obsolete—and in the process, relinquish the final quality that differentiates us from machines and makes us human.

Instead of asking whether AI can learn the one quality that makes humans creative, then, the more pertinent question is: should we let it?

The decision, for now, is in our (uniquely creative) hands.
