Exclusive: Secret contract tied NSA and security industry pioneer | Reuters - 0 views

  • Documents leaked by former NSA contractor Edward Snowden show that the NSA created and promulgated a flawed formula for generating random numbers to create a "back door" in encryption products, the New York Times reported in September. Reuters later reported that RSA became the most important distributor of that formula by rolling it into a software tool called Bsafe that is used to enhance security in personal computers and many other products.Undisclosed until now was that RSA received $10 million in a deal that set the NSA formula as the preferred, or default, method for number generation in the BSafe software, according to two sources familiar with the contract. Although that sum might seem paltry, it represented more than a third of the revenue that the relevant division at RSA had taken in during the entire previous year, securities filings show.
  • RSA, meanwhile, was changing. Bidzos stepped down as CEO in 1999 to concentrate on VeriSign, a security certificate company that had been spun out of RSA. The elite lab Bidzos had founded in Silicon Valley moved east to Massachusetts, and many top engineers left the company, several former employees said.And the BSafe toolkit was becoming a much smaller part of the company. By 2005, BSafe and other tools for developers brought in just $27.5 million of RSA's revenue, less than 9% of the $310 million total."When I joined there were 10 people in the labs, and we were fighting the NSA," said Victor Chan, who rose to lead engineering and the Australian operation before he left in 2005. "It became a very different company later on."By the first half of 2006, RSA was among the many technology companies seeing the U.S. government as a partner against overseas hackers.New RSA Chief Executive Art Coviello and his team still wanted to be seen as part of the technological vanguard, former employees say, and the NSA had just the right pitch. Coviello declined an interview request.An algorithm called Dual Elliptic Curve, developed inside the agency, was on the road to approval by the National Institutes of Standards and Technology as one of four acceptable methods for generating random numbers. NIST's blessing is required for many products sold to the government and often sets a broader de facto standard.RSA adopted the algorithm even before NIST approved it. The NSA then cited the early use of Dual Elliptic Curve inside the government to argue successfully for NIST approval, according to an official familiar with the proceedings.RSA's contract made Dual Elliptic Curve the default option for producing random numbers in the RSA toolkit. No alarms were raised, former employees said, because the deal was handled by business leaders rather than pure technologists.
  • Within a year, major questions were raised about Dual Elliptic Curve. Cryptography authority Bruce Schneier wrote that the weaknesses in the formula "can only be described as a back door."

Bacteria from bees possible alternative to antibiotics - Lund University - 0 views

  • Raw honey has been used against infections for millennia, before honey - as we now know it - was manufactured and sold in stores. So what is the key to its’ antimicrobial properties? Researchers at Lund University in Sweden have identified a unique group of 13 lactic acid bacteria found in fresh honey, from the honey stomach of bees. The bacteria produce a myriad of active antimicrobial compounds. 
  • While the effect on human bacteria has only been tested in a lab environment thus far, the lactic acid bacteria has been applied directly to horses with persistent wounds. The LAB was mixed with honey and applied to ten horses; where the owners had tried several other methods to no avail. All of the horses' wounds were healed by the mixture.

Elusive particle that is its own antiparticle observed -- ScienceDaily - 0 views

  • Using a two-story-tall microscope floating in an ultralow-vibration lab at Princeton's Jadwin Hall, the scientists captured a glowing image of a particle known as a "Majorana fermion" perched at the end of an atomically thin wire -- just where it had been predicted to be after decades of study and calculation dating back to the 1930s.
  • The hunt for the Majorana fermion began in the earliest days of quantum theory when physicists first realized that their equations implied the existence of "antimatter" counterparts to commonly known particles such as electrons. In 1937, Italian physicist Ettore Majorana predicted that a single, stable particle could be both matter and antimatter. Although many forms of antimatter have since been observed, the Majorana combination remained elusive.
  • Despite combining qualities usually thought to annihilate each other -- matter and antimatter -- the Majorana fermion is surprisingly stable; rather than being destructive, the conflicting properties render the particle neutral so that it interacts very weakly with its environment. This aloofness has spurred scientists to search for ways to engineer the Majorana into materials, which could provide a much more stable way of encoding quantum information, and thus a new basis for quantum computing.
