Renewed concerns about terrorists hiding electronic messages when they plan attacks are pitting technology companies against lawmakers.
Apple CEO Tim Cook defended personal privacy and the use of encryption on iPhones during a Friday interview with Charlie Rose on CBS This Morning.
Some U.S. lawmakers back legislation that would force U.S. tech companies to turn over encrypted data on smartphones when ordered by a judge.
Cook said the tradeoff between privacy and security is "only a simplistic view — we can have both."
Cook said Apple complies with court-ordered warrants to produce information as required by law enforcement, but said of encrypted data on iPhones, "We don't have it to give" because Apple's iPhones running versions after iOS 4 keep decryption keys on a user's iPhone.
Sen. Richard Burr, chairman of the Senate Intelligence Committee, is reportedly working on encryption legislation.
FBI Director James Comey recently testified about concerns that terrorists can use encrypted apps to plan attacks.
Businesses that sell phones whose stored messages can't be decrypted by third parties or apps that encrypt voice and data end-to-end must be able to unencrypt if given a court order, Comey said.
