# Storage Bridge Node Registration

This file outlines the Flashback API's node registration and organization key management features. The node registration system allows bridge nodes to register with the platform and manage cryptographic keys for secure communication. Organization keys are used for authenticating and authorizing node operations.

{% hint style="info" %}
To perform organization key operations, you must be authenticated by means of one of the following methods: [BearerAuth](/support-reference/platform-api-reference.md#http-bearer-authentication). Node registration operations do not require authentication as they use cryptographic signatures for verification.
