White House Drops Plan Requiring Access to Encrypted Data

The Obama administration has backed down in its bitter dispute with Silicon Valley over the encryption of data on iPhones and other digital devices, concluding that it is not possible to give American law enforcement and intelligence agencies access to that information without also creating an opening that China, Russia, cybercriminals and terrorists could exploit. With its decision, which angered the F.B.I. and other law enforcement agencies, the administration essentially agreed with Apple, Google, Microsoft and a group of the nation’s top cryptographers and computer scientists that millions of Americans would be vulnerable to hacking if technology firms and smartphone manufacturers were required to provide the government with “back doors,” or access to their source code and encryption keys.
