What are the challenges of implementing blockchain for IoT security?

Secure provisioning refers to a process by which devices are set up with unique credentials and encryption keys to ensure they are properly configured for secure operation. This is crucial for protecting sensitive data and ensuring that only authorized users or systems can access the device or its data. By ensuring that each device has its own unique set of credentials and encryption keys, secure provisioning helps prevent unauthorized access, tampering, or interception of data. Overall, it is a fundamental aspect of maintaining the security and integrity of connected devices and systems.
