    FCW Federal Computer Week ^ | August 21, 2015 | Sean Lyngass
    An official timeline of the Office of Personnel Management breach obtained by FCW pinpoints the hackers' calibrated extraction of data and the government's step-by-step response. It illuminates a sequence of events that lawmakers have struggled to pin down in public hearings with Obama administration officials. The timeline makes clear that the heist of data on 22 million current and former federal employees was one sustained assault rather than two separate intrusions to steal background investigation data and personnel records. The document, which bears the seals of OPM and the Department of Homeland Security, is dated July 14 and was prepared...
  • High-quality random numbers can now be computed with much less effort

    A big win for encryption, more efficient complex simulations Last week, computer scientist researchers at the University of Texas at Austin published a draft paper describing a new, more efficient way of generating truly random numbers that can be used everyday encryption situations like mobile banking, statistics, electronic voting and complex simulations, among other applications. At the university, computer science professor David Zuckerman and graduate student Eshan Chattopadhyay developed a method of taking two weakly random numbers and combining them into a single sequence of truly random numbers. In the past, the task of generating truly random numbers for encryption...
  • Two convicted for refusal to decrypt data

    Two people have been successfully prosecuted for refusing to provide authorities with their encryption keys, resulting in landmark convictions that may have carried jail sentences of up to five years. The government said today it does not know their fate. The power to force people to unscramble their data was granted to authorities in October 2007. Between 1 April, 2008 and 31 March this year the first two convictions were obtained. The disclosure was made by Sir Christopher Rose, the government's Chief Surveillance Commissioner, in his recent annual report. The former High Court judge did not provide details of the...

    INTERPOL ^ | 15 May 2008 | INTERPOL media release
    BOGOTA, Colombia - INTERPOL today presented the results of its forensic examination of eight seized FARC computer and hardware exhibits following a request for assistance in March of this year by Colombia, one of INTERPOL's 186 member countries. INTERPOL Secretary General Ronald K. Noble advised senior Colombian law enforcement officials that INTERPOL's team of forensic experts discovered 'no evidence of modification, alteration, addition or deletion' in the user files of any of the three laptop computers, three USB thumb drives and two external hard disks seized during a Colombian anti-narcotics and anti-terrorist operation on a FARC camp on 1 March...
  • Digg losing control of their site (HD-DVD encryption keys were posted)

    Excerpt - The folks at have let the social news genie out of the bottle, and now they can't control it. Since the HD-DVD encryption code was discovered and published, readers at Digg have been repeatedly submitting stories with the 16 digit hex code in the titles and bodies. Just as quickly as these posts crawl up the Digg charts, admins seem to be deleting them. Just search Google for 09 F9 and you'll find the key. Will AACS send a Cease and Desist to InfoWorld because I posted the text "09 F9"? If so, we might as well...

    RSA-640 Factored By Eric W. Weisstein November 8, 2005--A team at the German Federal Agency for Information Technology Security (BSI) recently announced the factorization of the 193-digit number 310 7418240490 0437213507 5003588856 7930037346 0228427275 4572016194 8823206440 5180815045 5634682967 1723286782 4379162728 3803341547 1073108501 9195485290 0733772482 2783525742 3864540146 9173660247 7652346609 known as RSA-640. The team responsible for this factorization is the same one that previously factored the 174-digit number known as RSA-576 (MathWorld headline news, December 5, 2003) and the 200-digit number known as RSA-200 (MathWorld headline news, May 10, 2005). RSA numbers are composite numbers having exactly two prime factors (i.e.,...

    A completely new kind of computer is rising on the technology horizon, and it has just reached a significant milestone.  A quantum computer, a device first suggested decades ago by Richard Feynman and others, has been constructed by Isaac Chuang and his coworkers at IBM?s Almaden Research Center in California.  The prototype quantum computer uses entangled nuclear spins for storage and has a capacity of seven ?qubits?, a term that will be discussed below.  Using a quantum-computing algorithm developed by AT&T's Peter Schor in 1995, this quantum computer has factored the number 15 into its prime- factors, 3 and...
