Network Security Input Output System with Heterogeneous Redundancy

The patent divides the single-point communication structure into multiple parallel communication paths (input branching module creates multiple input channels, arbitration branching module creates multiple output channels). This segmentation allows the system to distribute traffic across multiple paths, preventing single-point vulnerabilities and enabling security mechanisms like voting and memory erasure on each path independently.

The patent introduces intermediary modules (input proxy module, output proxy module, arbitration proxy module) that act as mediators between the communication paths and the core processing units. These proxies implement security functions including memory erasure, voting, and backdoor verification, thereby enhancing security without requiring fundamental changes to the communication architecture.

The patent implements dynamic heterogeneity by allowing different communication paths to use different security mechanisms and redundancy levels. The system can dynamically adjust which paths are active, switch between different voting schemes, and apply memory erasure at different rates based on security requirements. This dynamic approach enables the redundancy mechanism to adapt to various communication scenarios.

The patent applies different security qualities to different parts of the communication system. Critical paths may have full voting and memory erasure, while less critical paths may have simplified mechanisms. The input and output proxies can apply different levels of security processing to different messages based on their sensitivity, thereby making the redundancy mechanism adaptable to various communication requirements.
