Germany's main hackers' association contradicted EU security officials on Thursday by demanding strictly confidential data handling across the board online, using readily available encryption methods.

This follows a briefing paper for EU interior ministers released by the EU's counter-terrorism coordinator Gilles de Kerchove on Wednesday in the wake of this month's terror attacks in Paris.

EU's De Kerchove wants "back doors" to consumers' data

The EU paper said Internet and communications companies should be "obliged" to "provide" authorities in EU member nations with electronic access keys, sometimes called "back doors."

Responding, the Chaos Computer Club (CCC) said on its blog Thursday that "anyone who transfers or archives customers' data unencrypted and thereby endangers their security must face significant penalties."

Secure public, instead of 'militarization'

The CCC demanded that the millions spent by nations to "militarize" networks to spy on their citizens be invested instead in the construction of secure systems and technical training for the public.

"Effective cryptography must become the obligatory standard in communications via the Internet," the club said, adding that governments should "heave overboard" their plans for total surveillance.

Digital self-defense

The CCC accused German Interior Minister Thomas de Maiziere of ignoring the reality that more or less technically adept people could hide communications, making politicians' calls to regulate encryption practically unenforceable.

CCC spokesman Jan Girlich said the need for "digital self-defense" for individuals had been highlighted by recent disclosures, such as Edward Snowden's whistle-blowing on the American NSA and Britain's GCHQ spy agencies.

Last week, British Prime Minister David Cameron said the world should expose digital "safe havens" used by terrorists to talk among themselves even though industry was boosting encryption services.

Last October, the new FBI Director James Corney said that encryption features built into new cell phones marketed by Google and Apple could hurt law enforcement.

If it became the norm, suspects would "walk free," he told the Brookings Institution think tank.

The American Civil Liberties Union said a "couple" of anecdotal case descriptions from the FBI was not enough to argue against encryption.

Use Privacy Guard, urges agency

Germany's Federal Office for Security in Information Technology (BSI) recently urged business to make greater use of a publicly available encryption method known as GNU Privacy Guard or GnuPG.

On Monday, Britain's Guardian newspaper reported that documents provided by Snowden showed that in 2008 the GCHQ had saved emails from journalists at the New York Times, The Washington Post, the BBC, France's Le Monde and other media outlets.

GCHQ told the Guardian that its actions met strict legal guidelines.
