Abstract: The present invention is directed to a package having a tear-away opening. The package comprises an outer substrate layer, an inner aseptic layer secured to the outer substrate layer, and a cut in the outer substrate layer. In order to preserve the product in the package, the cut is of a predetermined depth such that the cut does not puncture the inner aseptic layer. The cut, however, is sufficiently deep so that a predetermined portion of the package may be torn off at the cut. The present invention also includes methods for manufacturing and opening a package having a tear-away opening. The method for manufacturing a package having a tear-away opening generally includes the steps of providing an outer substrate layer, securing an inner aseptic layer to the outer substrate layer, making a cut of predetermined depth in the outer substrate layer such that the cut does not puncture the inner aseptic layer, and then forming a package.

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 usefuil 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.
