Terrorist attacks in Paris have ignited a new round of concerns over encryption on smartphones. Some experts have blamed the attacks on the growth of cheap or free smartphone apps like WhatsApp or Chatsource that encrypt messages. Al-Qaeda and ISIS have probably built their own proprietary encryption protocols for Internet and mobile communications, expert Darren Hayes says. Hayes: “If France didn’t pick up this attack in advance, it’s a wake-up call for all of us” Congress needs to find ways to force Apple and Google to redesign their operating systems to relinquish encryption keys under court order.”]
