Abstract:
1. A method of secure communication between two or more hosts using a public network, such as the Internet, comprising: setting up one or more secure virtual networks (SVN) to enable two or more hosts to communicate over said public network; assigning an SVN identifier that is independent of network transmission and routing protocols for each host in the SVN environment, wherein said SVN identifier identifies said hosts for the SVN environment; designating at least one of said hosts as a master node to control operation of the SVN environment; communicating SVN setup and control information along with information packets communicated over the network; sending a request for secure communications from one host to said master node; granting or denying said communication request based on one or more SVN parameters stored on said master node; establishing a secure communication session among two or more hosts; securing said information packets by inserting a secure virtual network message (SVNM) into the payload portion of a packet; communicating information packets over the secure communication session; and terminating the SVN session by said master node.
