dead man's switch?

wired | The strategy employed by NSA whistleblower Edward Snowden to discourage a CIA hit job has been likened to a tactic employed by the U.S. and Russian governments during the Cold War.

Snowden, a former systems administrator for the National Security Agency in Hawaii, took thousands of documents from the agency’s networks before fleeing to Hong Kong in late May, where he passed them to Guardian columnist Glenn Greenwald and documentary filmmaker Laura Poitras. The journalists have handled them with great caution. A story in the German publication Der Spiegal, co-bylined by Poitras, claims the documents include information “that could endanger the lives of NSA workers,” and an Associated Press interview with Greenwald this last weekend asserts that they include blueprints for the NSA’s surveillance systems that “would allow somebody who read them to know exactly how the NSA does what it does, which would in turn allow them to evade that surveillance or replicate it.”

But Snowden also reportedly passed encrypted copies of his cache to a number of third parties who have a non-journalistic mission: If Snowden should suffer a mysterious, fatal accident, these parties will find themselves in possession of the decryption key, and they can publish the documents to the world.

“The U.S. government should be on its knees every day begging that nothing happen to Snowden,” Greenwald said in a recent interview with the Argentinean paper La Nacion, that was highlighted in a much-circulated Reuters story, “because if something does happen to him, all the information will be revealed and it could be its worst nightmare.”
