How even key escrow won’t work for Cameron

How is Cameron going to ensure that law enforcement can read all communications? One way would be to provide systems with ”back doors”; introducing intentional vulnerabilities. We all know that won’t work. Or rather will work much better than intended, if you get my drift.

Some, including Steve Gibson, maintain that it can in fact be done by having law enforcement maintain a secret, well-guarded, key and mandating that all messages sent are including that encryption target in every message. That would allow LE to decrypt it using a very carefully guarded secret key, if need be. All this without weakening the actual encryption mechanism.

The problem with this is that LE can’t know if everyone is following the law without actually trying to decrypt messages flying by. And to do that on a large scale by necessity implies that the “highly guarded” secret key must be available on a large number of systems, exposing it to compromise.

Even if we stipulate that there is some, hitherto unknown, mechanism that allows LE to verify that messages in fact include the LE destination without having the secret key available, they still can’t know if the encryption is valid until attempted. For instance, the encrypted symmetric key may be intentionally wrong. Or, the encrypted message may contain another encrypted message which does not contain the LE mandated item. And that, in turn, can only be discovered once you perform the actual decryption, which requires the ”highly protected” government key.

In other words, it won’t work.

You cannot trust

Caspar Bowden spoke at the 31c3 conference. Snippets:

I told my technology officers at MicroSoft that if you sell cloud computing services to your own governments, this means that the NSA can do unlimited surveillance on that data. […] two months later they did fire me.

“Technology officers” represent MicroSoft in their respective countries.

On the “FISA Amendment Act of 2008 (Sec 702)”:

This means if you are not American, you cannot trust U.S. software services!!


The US congress was laughing, laughing at the idea that you have privacy rights. That is the climate of the US privacy debate.

“You”, in that sentence, refers to non-US persons outside the US.

FISAAA offers zero protection to foreigner’s data in US clouds. 

US is “exceptionally exceptional”: The number of references in surveillance law that discriminate by citizenship/nationality (NOT geography of communication path), per country:

US: 40, UK: zero, Germany: 1, Canada: 2, New Zeeland: 2, Australia: 2. No others.

On whistleblowers:

We need to give them watertight asylum, and probably some incentives, some rewards. I actually proposed to the parliament [EU parliament] that the whistleblower should get 25% of any fines subsequently exacted.

 Big applause from the audience…

How do people know politicians and officials aren’t influenced by fear of NSA spying in their own private life? […] this is highly corrosive to democracy!


The thoughts that Edward Snowden has put in the minds of people cannot now be unthought.

What this all means, in practice, relating back to medical applications, is that we (Europeans) can’t use US software or services, which includes medical records such as EPIC, data analysis services such as IMS Health, data storage such as Amazon, Azure, iCloud, backup solutions (unless encrypted client side), or even US operating systems such as Android, iOS, OSX, Windows, a series of embedded OS, etc. At least not if we care about our patient’s right to privacy.

EU home affairs chief secretly worked with US to undermine new privacy laws

EU home affairs chief secretly worked with US to undermine new privacy laws, campaigners claim — Tech News and Analysis: “The digital rights group Access has revealed an email that suggests outgoing EU Home Affairs Commissioner Cecilia Malmström collaborated with the Americans in a successful attempt to water down Europe’s new privacy laws.”
