Abstract
A system and method are disclosed for authenticating users and services communicating over an insecure network. Each user and service has a pass-phrase used for authentication. However, the pass-phrases are not revealed during the authentication process as challenge-response techniques are used to keep the pass-phrase secret. In addition, the users and services do not need to know nor do they learn each other's pass-phrases making the process useful in a distributed environment. Pass-phrases are known by an authentication entity with which the service communicates to authenticate both users and services. Users may have identities in and services may support a number of realms, each of which may be viewed as large collection of users (e.g., CompuServe.com). Users choose the realm in which they would like to be authenticated. In one embodiment of the present invention, the system and method are adapted for use with the HyperText Transfer Protocol of the World Wide Web so that secure transactions may be accomplished between users and services communicating via the Internet.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
