  • System for remote pass-phrase authentication
    Patent number: 6487667
    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.
