Abstract: Invention selectively enables usage of services and communication conduits in a computer network, wherein the enablement is contingent on usage conditions, resulting in containment of the spread of unauthorized activity within a networked computer system and limiting the scope of results when an element becomes part of a hostile execution environment. Instead of protecting individual networked elements from a potentially hostile execution environment, the elements' usage of the networked environment is restricted to the extent of selectively allowing usage of needed resources explicitly authorized for use by such elements.

Abstract: Client software is modified by a translator to use unique variant of linguistic interface of a service. An interceptor pre-processes subsequent client service requests from translated unique linguistic interface to standard linguistic interface implemented by service. Usage of linguistic interfaces of service is contained, rendering service incapable of executing arbitrary input, even if such input is crafted specifically for the service interface.

Abstract: Interface elements of a logic module are translated by renaming, adding dummy elements, and/or associating traps with dummy elements. Trusted parties are made aware of renamed interface elements and thereby allowed to properly communicate with logic module. Untrusted parties are kept unaware of the interface translation, with attempts to guess correct interface elements likely to fail, instead resulting in communication attempts with dummy elements and subsequent trapping of the untrusted parties.

Abstract: A method and apparatus searches table information using keys of varying lengths. Based on criteria, the method selects one of three processes for performing the search. The first routine is a reverse hash search process which is useful for searching information with few key lengths. The second process is a hierarchical search routine which is useful for searching information with many key lengths. The third process is a compressed radix tree search which is useful for searching information that presents significant time barriers to the first two routines.
