Microsoft is reportedly looking for new ways to more securely encrypt its internet traffic, amid concerns that the National Security Agency (NSA) may have breached its network. Citing sources familiar with the matter, the Washington Post reports that Microsoft executives are discussing possible encryption measures this week, and will determine how soon to implement them. The move comes following revelations that the NSA has been secretly collecting user data from other tech giants. In October, the newspaper reported that the agency has been tapping into Google and Yahoo networks to obtain user information, according to documents obtained from former NSA contractor Edward Snowden.
