Five-Eyes Intelligence Services Choose Surveillance Over Security
The Five Eyes -- the intelligence consortium of the rich English-speaking countries (the US, Canada, the UK, Australia, and New Zealand) -- have issued a "Statement of Principles on Access to Evidence and Encryption" where they claim their needs for surveillance outweigh everyone's needs for security and privacy. ...the increasing use and sophistication of certain…

Quantum Key Distribution Whitepaper
https://www.ncsc.gov.uk/whitepaper/quantum-key-distribution (ncsc.gov.uk) This white paper describes our current position on quantum key distribution (QKD). QKD is an approach to key distribution that relies on the properties of quantum mechanics to provide security. ...
For all the practical, business and security reasons given above, at this point in time we:
do not endorse QKD for any … -
The Alice and Bob After Dinner Speech
John Gordon: The Alice and Bob After Dinner Speech (urbigenous.net) Good evening Ladies and Gentlemen.
There comes a time when people at a technical conference like this need something more relaxing. A change of pace. A shift of style. To put aside all that work stuff and think of something refreshingly different.
So let's talk about coding … -

Asymmetric Cryptography: Works Like Magic
Asymmetric Cryptography: Works Like Magic (cyberhoboing with dominic tarr) It’s a common complaint that cryptography is too hard for regular people to understand - and that all our current cryptographically secure applications are designed for cyborgs and not humans. While...

A hacker stole $31M of Ether - how it happened and what it means for Ethereum
Yesterday, a hacker pulled off the second biggest heist in the history of digital currencies.
Around 12:00 PST, an unknown attacker exploited a critical flaw in the Parity multi-signature wallet on the Ethereum network, draining three massive wallets of over $31,000,000 worth of Ether in a matter of minutes. Given a couple more hours, the hacker … -

Defeating Quantum Algorithms with Hash Functions
In this post I’ll explain why quantum computers are useless to find hash function collisions, and how we can leverage this powerlessness to build post-quantum signature schemes. I’ll then describe a quantum computing model that you can try at home, and one where hash function collisions are easy to find...

TLS 1.3 FTW
In common slang, FTW is an acronym "for the win" and while that's appropriate here, I think a better expansion is "for the world."
We're pleased to announce that we have sponsored the development of TLS 1.3 in OpenSSL. As it is one of the most widely-used TLS libraries, it is a good investment for the … -
Against DNSSEC
All secure crypto on the Internet assumes that the DNS lookup from names to IP addresses are insecure. Securing those DNS lookups therefore enables no meaningful security. DNSSEC does make some attacks against insecure sites harder. But it doesn’t make those attacks infeasible, so sites still need to adopt secure transports like TLS. With TLS …

Something like HTTPS Everywhere for new Opera?
I'm looking for an extension that will automatically redirect-to-HTTPS for particular domains, e.g. to ensure that I'm using the secure version of Wikipedia, etc., whenever I go there. The HTTPS Everywhere plugin from the EFF does this for Firefox and Chrome; what can I do to make this work in Opera?

Phone Security == Computer Security
Dan gets paranoid and despairs about the ease with which mobile devices can be stolen, the wealth of personal information stored on them, and the under-use of readily-available encryption tools.
