Microsoft is moving on a major new effort to encrypt its Internet traffic amid fears that the National Security Agency may have broken into its global communications links, said people familiar with the emerging plans.

With such a move to expand encryption, Microsoft would join Google, Yahoo, Facebook and others in hardening its defenses. The new investments in encryption technology stand to complicate surveillance efforts — by governments, private companies and criminals — for years, experts say.
