On January 21 a text message flashed on phones held by the protesters Zimmermann always wanted to take widespread encryption to the next level: thronging Kiev’s Independence Square. Ukraine’s president, Viktor Yanukovych, secure telephony. Until the past few years, however, voice transmissions did not was then still clinging to power and brutalizing opponents. The message—from generally take the digital form required by cryptographic technologies. In the the number 111—read: “Dear subscriber, you are registered as a participant in a 1990s he’d built a prototype, but it required using modems tethered to PCs. mass disturbance.” Widely presumed to have been sent from Yanukovych’s “That product was never going to get any traction,” he says. Today, telephone security apparatus to all phones in the protest zone, the message was a stark reminder of how mobile phones can be used for surveillance. companies and carriers do encrypt calls—but they hold the crypto keys in their Soon after, a Ukrainian man walked into a nondescript office in National Harbor, servers, and “phone companies have historically been very coöperative with Maryland, and sought help from a man named Phil Zimmermann. wiretapping,” he says. Zimmermann’s protocols instead kept the keys only at endpoints—preventing the carriers and even his own servers from decrypting Zimmermann is a cryptologist.

hands of military and government leaders, this effort may signal a shift toward mass-market phones that are far more private and secure.

Project Loon ITECH UPDATE Billions of people could get online for the first time thanks to helium balloons that Google will soon send over many places cell towers don’t reach. Google has launched hundreds of these balloons into the sky, lofted by helium, which is 15 meters across, that resemble giant white pumpkins.
