[As Encryption Spreads, U.S. Grapple with Clash between Privacy, Security](http://www.washingtonpost.com/world/national-security/as-encryption-spreads-us-worries-about-access-to-data-for-investigations/2015/04/10/7c1c7518-d401-11e4-a62f-ee745911a4ff_story.html?wprss=rss_national-security) – Ellen Nakashima and Barton Gellman writing in The Washington Post reveal that federal officials are considering a variety of means of ensuring access to encrypted communications, including split key approaches, as well as, in certain circumstances, mirror accounts. Under the split key approach (difficult from an engineering and cryptography standpoint), a technology company creates a decryption key that is split into pieces, with different pieces held by different parties, and all of the pieces are needed for decryption. But even aside from the question of trust in the holders of the key parts, risk of disclosure of the decrypted information and the like, as security expert/researcher, Dino A. Dai Zovi (@dinodaizovi) tweeted: “The big question of the #cryptodebate isn’t whether vendors can make a decryption key for USG, but what happens when other [governments] want it too?”
