  • Multi-factor password-authenticated key exchange
    Patent number: 8776176
    Abstract: Apparatus, methods, and computer program products are disclosed that enable a first computer and a second computer to mutually authenticate each other over a network.

The first authentication evidence is used to prove to the second computer that the first computer has access to a first plurality of authentication secrets without exposing the first plurality of authentication secrets. In addition, the second computer sends second authentication evidence to the first computer. The second authentication evidence is used to prove to the first computer that the second computer has access to a second plurality of authentication secrets without exposing the second plurality of authentication secrets.
