<https://www.washingtonpost.com/news/the-switch/wp/2016/03/29/why-the-fight-b...> The Justice Department has called off a high-profile legal battle with Apple after it was able to unlock an iPhone used by one of the San Bernardino, Calif., shooters without the company's help. But rather than resolve the fight, this latest development is likely to motivate Apple and other companies to strengthen the security of their devices even more and force the government to keep up with any new security measures, technology executives and security analysts said. "They're in an arms race," said Matthew Blaze, a cryptography researcher and professor at the University of Pennsylvania. "The FBI is trying to find new ways in, and Apple is trying to find new ways to defend against that." [...] Stewart Baker, a former Department of Homeland Security senior policy official and now a partner at Steptoe & Johnson, argues that Apple's stance in the San Bernardino case gives the government little incentive to tell the company how it was able to break in. "If Apple's position is, 'We aren't going to help you, and as soon as you tell us about a problem we're going to lock you out again,' you're basically saying the FBI should be complicit in locking themselves out of the phones," he said. But the government also must consider keeping Americans' tech safe from other adversaries, including hostile hackers working on behalf of foreign intelligence agencies and cybercriminals, Blaze said. "This vulnerability helped them get into this particular handset, but now they need to be thinking about who else could potentially use it to do the same thing," he said. Blaze and Baker agree on one point: This isn't the end of the issue. "This is a conflict that's going to happen," Baker said.
