METHODS AND SYSTEMS FOR PROVIDING AND CONTROLLING CRYPTOGRAPHICALLY SECURE COMMUNICATIONS ACROSS UNSECURED NETWORKS BETWEEN A SECURE VIRTUAL TERMINAL AND A REMOTE SYSTEM

摘要

An endpoint, method, and authorization server are disclosed which can be used to allow concurrent secure and clear text communication. An endpoint includes a computing system including a programmable circuit operatively connected to a memory and a communication interface, the communication interface configured to send and receive data packets via a data communications network. The endpoint also includes a filter defined in the memory of the computing system, the filter configured to define one or more access lists, each access list defining a group of access permissions for a community of interest. The community of interest includes one or more users, and an access list from among the one or more access lists defines a set of clear text access permissions associated with a community of interest. The endpoint also includes a driver executable by the programmable circuit, the driver configured to cooperate with the communication interface to send and receive data packets via the data communications network. The driver is also configured to selectively split and encrypt data into a plurality of data packets to be transmitted via the data communications network based at least in part upon the contents of the one or more access lists.
