Abstract
Apparati, methods, and computer-readable media for improving the security of communications networks. An embodiment of the present invention is a system for enabling smart devices (1401, 1402, 1403) to communicate with each other over a network (1450) without human intervention. The system comprises at least two bidirectional smart devices (1401, 1402) adapted to send and receive messages (1460) over the network (1450). Each smart device (1401, 1402) is coupled to the network (1450) via a bidirectional intelligent chip, logic device, or smart device (1411, 1421). In message sending mode, intelligent chip, logic device, or smart device (1411) appends an identifier (1417) to each message (1460) emanating from its associated sending smart device (1401). The identifier (1417) comprises a fixed portion (1415, 1416) uniquely identifying the associated sending smart device (1401), and a variable portion (1414). The receiving intelligent chip, logic device, or smart device (1421) invokes a module (1423) contained within each intelligent chip (1411, 1421) configured to screen incoming messages (1460), by validating both the fixed and variable portions of the identifier (1417).
