Security Solutions - Single Sign On

A Single Sign-On system is a set of software components, usually distributed over a network, which allow a user to log into his workstation once, and thereafter start applications and network Login Session's without any further Authentication. The initial Login may be carried out using Credentials, such as a User ID and Password, or another technology, such as a Public Key Infrastructure or a Smart Card.

A Smart Card is a credit-card-sized hardware device used in a cryptographic Authentication system. Some Smart Card's operate on the basis of a frequently changing code: a user who wishes to Login must enter his own User ID and the current code displayed by the card. An alternate system uses a cryptographic calculator, where the user logs into a system, which displays a challenge string. The user keys this string into his own Smart Card, which prints a response. The response is used as the user's password for the Login Session.
