Details of iOS and Android Device Encryption

swillden writes: There's been a lot of discussion of what, exactly, is meant by the Apple announcement about iOS8 device encryption, and the subsequent announcement by Google that Android L will enable encryption by default. Two security researchers tackled these questions in blog posts:

Matthew Green tackled iOS encryption, concluding that the change really boils down to applying the existing iOS encryption methods to more data. He also reviews the iOS approach, which uses Apple's "Secure Enclave" chip as the basis for the encryption and guesses at how it is that Apple can say it's unable to decrypt the devices. He concludes, with some clarification from a commenter, that Apple really can't (unless you use a weak password which can be brute-forced, and even then it's hard).

Nikolay Elenkov looks into the preview release of Android "L." He finds that not only has Google turned encryption on by default, but appears to have incorporated hardware-based security as well, to make it impossible (or at least much more difficult) to perform brute force password searches off-device.

Bitcoin prices have dropped nearly 50% in three months

Over the past three months, the price of the cryptocurrency bitcoin has fallennearly 50 percent going from $630 per bitcoin to $320 per bitcoin, according to CoinDesk's Bitcoin Price Index, which averages the prices on major exchanges.

That's obviously an extreme shift but bitcoin trading prices are notoriously volatile, sometimes making similar percentage drops in a matter of hours or days.

The difference here is that it appears to be a slow, measured pattern of decline. There have been bits of major regulatory news in the past few months, including New York's proposed rules for virtual currencies and Russia's proposal to punish their use. But that doesn't seem to haveproduced the same type ofseismic shifts as when China ordered local payment processors to stop transactions involving digital currencies such as bitcoin.

Instead, Jerry Brito, the executive director of industry-backed think tank Coin Center, believes the downward trend may actually be related to the increased popularity of bitcoin among merchants in recent months. In September, Overstock.com became the first major online retailer to accept thecryptocurrency globally.

"It's hard to tell what exactly causes these price movements, but what I think makes most sense is that as Bitcoin merchant adoption grows, there is increasing sell pressure in the market," Brito says. "Because there are not yet very good hedging instruments for bitcoin, merchants that accept bitcoin for payment will immediately sell so as to not be exposed to any volatility." Basically, merchants don't want to hold on to the bitcoins they accept as payment.

Thus, he says, there's a constant sell pressure, which he believes may have snowballed into the current downward trend. However, Brito is an optimist about the future of the market, saying that "needed hedging instruments are coming along very shortly" and that long-term investors may actually buy in the current low.

The $320 exchange rate the cryptocurrency is currently floating around is a substantial drop from the highs of last year when bitcoins reached more than $1,100 on some markets near the end of the year after dramatic surges.

Looking even further back shows just how turbulent 2013 and 2014 were for the overall currency and payment system experiencing major booms and busts at much more significant dollar levels than in its earlier year.

Bitcoin received intense media coverage as it experienced some growing pains, including regulatory turmoil, a bankruptcy scandal involving one of the most popular exchanges, and various attempts to unmask the cryptocurrency's mysterious creator.

But given all the hype the currency has received, it can be easy to forget that the system was launched only in 2009 and that the price stayed well below the current levels until the latter half of 2013.

Assange Appeals Swedish Court Decision to Uphold Arrest Warrant: Reports

STOCKHOLM, September 12 (RIA Novosti) - Lawyers for WikiLeaks founder Julian Assange, accused of rape and sex assault in Sweden, on Friday appealed a Stockholm judges ruling to uphold an arrest warrant issued for him, Swiss news outlets reported Friday.

We have filed a petition with the appeal court to hold a new hearing on the case, lawyer Thomas Olsson said as quoted by Dagens Nyheter newspaper.

The defense has been arguing that the warrant, issued for Assange in November 2010 should be overturned since the prosecutor has been refusing to travel to London to interrogate the WikiLeaks founder so far. By not allowing the Australian to make a statement from the Ecuadorian embassy in London, the extended time frame of the trial has become a violation of his right to due process, the lawyers said.

On July 16, the Stockholm City District Court reviewed the detention order on request by Assange and upheld the arrest warrant. The judge decided that there is still probable cause concerning the suspicions directed towards Julian Assange (unlawful coercion, sexual molestation and rape) there is still a risk that he will fail to appear or in some other way avoid participation in the investigation, according to the official press release.

Julian Assange launched the WikiLeaks website back in 2006, taking the role of its editor-in-chief. Wikileaks made its name by releasing scores of classified diplomatic and military documents from governments around the world, most notably the United States. The whistleblower was charged for sexual assault in Sweden in 2010. Assange denies the charges of rape as politically motivated.

The Wikileaks founder has been holed up in the Ecuadorean Embassy in London since seeking asylum there in June 2012. British police on guard outside the embassy ordered to arrest the Australian if he ever steps out.

Assange is trying to avoid his extradition to Sweden as he believes that it would lead to his further extradition to the United States, where he could be subject to rights violations.

Nobel Season Opens With Edward Snowden, Chili Research Spicing up Predictions

US physiologist David Julius has been touted by Sweden's leading daily Dagens Nyheter to win the medicine prize for discovering that pain receptors have the same reaction to pain, temperature and the spicy component of chili.

"David Julius's discoveries have given us a much deeper understanding of how feeling works and completely new possibilities to produce drugs against chronic pain," Maria Gunther, science editor at the paper wrote.

While the Nobel week begins with three science prizes -- including physics on Tuesday and chemistry on Wednesday, most of the speculation surround the coveted peace prize to be announced Friday.

This year's peace prize has drawn a record 278 nominations, including that for Snowden -- whose name was put forward by two Norwegian lawmakers for his exposure of widespread US electronic surveillance.

Snowden analyst would be a controversial choice as "many continue to see him as a traitor and a criminal", according to Kristian Berg Harpviken, director of the peace research institute Oslo (PRIO), one of few analysts to publish a list of potential winners.

Nonetheless the five members of the Nobel Committee could still give him the award to "underline the independence of the Nobel Committee" from the Norwegian and US authorities, according to Nobeliana.com, a website run by leading Norwegian Nobel historians.

- Too controversial -

Others have rubbished the Snowden speculation.

"Judging from the past, I can't see that coming. It's too controversial -- and Scandinavians are too fond of the (United) States," Robert Haardh, head of Stockholm-based Civil Rights Defenders told AFP.
