“Quantum physics enables perfectly secure cloud computing: Researchers have succeeded in combining the power of quantum computing with the security of quantum cryptography and have shown that perfectly secure cloud computing can be achieved using the principles of quantum mechanics. They have performed an experimental demonstration of quantum computation in which the input, the data processing, and the output remain unknown to the quantum computer.
[...] current trend of cloud computing: central remote servers are used to store and process data – everything is done in the “cloud.” The obvious challenge is to make globalized computing safe and ensure that users’ data stays private.
The latest research, to appear in Science, reveals that quantum computers can provide an answer to that challenge. “Quantum physics solves one of the key challenges in distributed computing. It can preserve data privacy when users interact with remote computing centers [...]
The scientists in the Vienna research group have demonstrated the concept of “blind quantum computing” in an experiment: they performed the first known quantum computation during which the user’s data stayed perfectly encrypted. The experimental demonstration uses photons, or “light particles” to encode the data. Photonic systems are well-suited to the task because quantum computation operations can be performed on them, and they can be transmitted over long distances.
The process works in the following manner. The user prepares qubits – the fundamental units of quantum computers – in a state known only to himself and sends these qubits to the quantum computer. The quantum computer entangles the qubits according to a standard scheme. The actual computation is measurement-based: the processing of quantum information is implemented by simple measurements on qubits. The user tailors measurement instructions to the particular state of each qubit and sends them to the quantum server. Finally, the results of the computation are sent back to the user who can interpret and utilize the results of the computation. Even if the quantum computer or an eavesdropper tries to read the qubits, they gain no useful information, without knowing the initial state; they are “blind.”" http://www.eurekalert.org/pub_releases/2012-01/uov-qpe011612.php

How litigation only spurred on P2P file sharing: “[...] the US Supreme Court in Grokster created a brand new legal doctrine, called inducement, that did not rely on either knowledge or control. That rule was aimed at capturing “bad actors” – those P2P providers who aimed to profit from their users’ infringement and whose nefarious intent was demonstrated by “smoking guns” in their marketing and other communications. But the inducement law failed to appreciate some of the other differences that make the software world special and thus led directly to the explosion in the number of P2P technologies. In understanding why, three other physical world assumptions come into play.

One is that it is expensive to create distribution technologies that are capable of vast amounts of infringement. Of course in the physical world, the creation of such technologies, like printing presses, photocopiers, and VCRs required large investment. Research and development, mass-manufacturing, marketing and delivery all require massive amounts of cash. Thus, the law came to assume that the creation of such technologies was expensive.

That led directly to the next assumption – that distribution technologies are developed for profit. After all, nobody would be investing those massive sums without some prospect of a return.

Finally comes the fourth assumption: that rational developers of distribution technologies won’t share their secrets with consumers or competitors. Since they needed to recoup those massive investments, they had no interest at all in giving them away.

All of these assumptions certainly can hold up in the software development context. For example, those behind Kazaa spent a lot on its development, squeezed out the maximum possible profit and kept its source code a closely guarded secret. By creating a law that focused on profits, business models and marketing, the Supreme Court succeeded in shaking out Kazaa and its ilk from the market.

But the Court failed to appreciate that none of these things are actually necessary to the creation of P2P file sharing software. [...]” http://www.itnews.com.au/News/279763,how-litigation-only-spurred-on-p2p-file-sharing.aspx

EUDataProtectionSupervisor: No privacy without net neutrality “78. Inspection techniques based on traffic data and inspection of IP payloads, i.e. the content of communications, may reveal users’ Internet activity: websites visited and activities on those sites, use of P2P applications, files downloaded, emails sent and received, from whom, on what subject and in which terms, etc. ISPs may want to use this information to prioritise some communications, such as video on demand, over others. They may want to use it to identify viruses, or to build profiles in order to serve behavioural advertising. These actions interfere with the right to the confidentiality of communications.” http://www.edps.europa.eu/EDPSWEB/webdav/site/mySite/shared/Documents/Consultation/Opinions/2011/11-10-07_Net_neutrality_EN.pdf

Why we secretly love LulzSec: “So for the last ten years I’ve been working in media, trying to raise awareness of the idea that maybe, just maybe, using insecure computers to hold your secrets, conduct your commerce and run your infrastructure is a shitty idea.

No one who mattered listened. Executives think it’s FUD. They honestly think that if they keep paying their annual AV subscriptions they’ll be shielded by Mr. Norton’s magic cloak.

Security types like LulzSec because they’re proving what a mess we’re in. They’re pointing at the elephant in the room and saying “LOOK AT THE GIGANTIC FUCKING ELEPHANT IN THE ROOM ZOMG WHY CAN’T YOU SEE IT??? ITS TRUNK IS IN YR COFFEE FFS!!!” [...]” http://risky.biz/lulzsec

MI6 to Rest of World: Cyber War is On. Anyone, Anywhere is Fair Game. Arm yourselves. “[...] it makes it OK for any government agency to target our servers and the tone of the article suggests moral impunity for government agencies engaging in these attacks. If it’s OK for British intelligence to hack (most likely) US based servers then it’s OK for Chinese officials to attack an ad network based in the USA if they run an ad for a dissident website.

At first glance this looks like a cute prank. But this attack may spark the beginning of a global cyber war fought by government agencies and private contractors, the logical conclusion of which is an Iron Curtain descending on what was once an open and peaceful communication medium.” http://markmaunder.com/2011/cyber-war-is-on/
