Definition
Key-based routing is a method for allowing access to resources and communication paths through specific cryptographic keys. For example, messages sent to a specific exchange are routed to queues with matching binding keys, while messages not matching the key are filtered out.
Common Key-Based Routing Applications
- VPNs: Virtual private networks (VPNs) widely use key-based routing to create secure connections between private networks and users. They give users specific cryptographic keys to grant them access to sensitive resources.
- Secure communication channels: Various communication channels, like encrypted messaging platforms, use key-based protocols, allowing users to share information securely.
- Access control list: Various network connection devices, such as routers and firewalls, use key-based routing protocols to implement access control lists (ACLs). ACLs then allow or disallow traffic based on specific cryptographic keys.
- Secure IoT communications: IoT devices use key-based routing to ensure secure communication between them and central systems.
