I've been tossing the idea around lately that something like a blockchain could be used as part of a larg-scale PKI - once you announce your public key and it gets several confirmations, then it would be hard for someone to announce that your key is something else after the fact and your not necessarily trusting a company or the government to do so.

But how do you prevent someone else from announcing before you.. or what incentive would their be for miners to mine... still plenty of issues not solved - but it could fix part of the problem.

The irony is that the mathematical foundations of bitcoin create a solid record of legitimate ownership that may be more ironclad against fraud than many of the systems employed by businesses today.

Tell that to the members of the Mt. Gox exchange.

Mt Gox had nothing to do with the blockchain... The reason that Mt Gox couldn't "go get the money back" *is* that the blockchain says its not their money any more. Which it isn't because someone went and spent it!

Perhaps you giggled because you don't understand it? There hasn't been any flaws with bitcoin itself and the block chain that caused coins to be spent by someone who didn't know the ECC private key... Loss-of-currency has occurred with poor third party implementations, e.g. using ECDSA and selecting the same value of k for multiple signatures (similiar to the mistake made by sony and the ps3) or Mt Gox which was either just outright fraud by the company or a severe implementation error.

The block chain is fairly effective at deciding "what came first" and after several confirmations becomes fairly infeasible for a bad actor to change - I don't know of any weaknesses provided your computing pool is large enough that no person controlls 50%. Well, or a quantum computer solving the discrete logarithm...

I unplugged the wrong thing in a datacenter once which took 20k domains offline. Traced the cable from the machine to the wall 2 or three times before pulling too..

They didn't have any cable management and only one border router..

Didn't lose my job, I was a very young sysadmin who was learning but good at what I did.. everyone kinda shrugged it off as a lesson learned.


Microsoft Open Technologies Is Closing: Good Or Bad News For Open Source? 110

BrianFagioli writes When Microsoft Open Technologies was founded as a subsidiary of Microsoft — under Steve Ballmer's reign — many in the open source community hailed it as a major win, and it was. Today, however, the subsidiary is shutting down and being folded into Microsoft. While some will view this as a loss for open source, I disagree; Microsoft has evolved so much under Satya Nadella, that a separate subsidiary is simply no longer needed. Microsoft could easily be the world's biggest vendor of open source software, which is probably one reason some people don't like the term.

No. Sorry. Government-only backdoors do not exist. They're by definition public. At the very least, they are public enough that every OTHER government will have the keys to it, too.

Not necessarily, Dual_EC_DRBG's potential back door lies in being able to choose the parameters of the protocol - namely choosing two points on the eliptic curve P and Q such that they know e where eP= Q. The only other way to "discover" this back door key would be solving the discrete logarithm problem which is the hardness assumption thats being used in the first place.


China Bans Government Purchases of Windows 8 200

itwbennett (1594911) writes "Last week, China's Central Government Procurement Center posted a notice on new requirements for government tender, that included, among other things, the mysterious request that Windows 8 be excluded from the bidding process on computer purchases. The agency could not be reached Tuesday, but China's state-controlled Xinhua News Agency said that the government was forbidding the use of Windows 8 after Microsoft recently ended official support for Windows XP."
