Abstract
Abstract An apparatus, method and system are disclosed for providing network security for executable code in computer and communications networks, such as providing network security for downloadable and executable Java programming language bytecode. The preferred apparatus embodiment includes a network interface for the reception and transmission of network information, such as an interactive world wide web page; and includes a processor having program instructions to determine whether network information includes a network language keyword, such as a Java applet. When the network information includes such a network language keyword, the processor includes further instructions is further responsive to generate the network language keyword having a distinctive reference to corresponding executable code, such as a distinctive Java class name, and to provide, for transmission by the network interface, the network information in which the network language keyword incorporates the distinctive reference. When the network language keyword incorporating the distinctive reference is invoked, the processor includes further instructions to provide, for downloading by the network interface, the corresponding executable code. The preferred apparatus embodiment is within a network server, and may also include a memory system for storage of the corresponding executable code.
