Some governments have national authentication frameworks[1] that define requirements for user authentication to government services, including requirements for passwords.

2. Hardware Security

These modules traditionally come in the form of a plug-in card or an external TCP/IP security device that can be attached directly to a server or general purpose computer. Each module contains one or more secure cryptoprocessor chips to prevent tampering and bus probing.
