IPCEXCL
IPCEXCL is a conceptual mechanism used in inter-process communication to provide exclusion-based access control over IPC channels and messages. In a typical IPCEXCL model, each channel is governed by an exclusion policy that determines which processes may participate in communication, based on identity, capabilities, or tokens. The goal is to prevent unauthorized or unintended message exchanges while allowing legitimate interactions to proceed with low latency.
Implementation and operation: A policy engine evaluates incoming and outgoing messages against configured rules. Process identity,
Applications and examples: IPCEXCL is discussed in theoretical works on secure IPC, multi-tenant and real-time systems,
Limitations and considerations: Implementing IPCEXCL adds complexity and potential performance overhead. Careful policy design is required
