How does data encryption enhance IoT security?

Data encryption plays a crucial role in ensuring the security and privacy of sensitive information when it is being transmitted between IoT devices and systems. Encryption involves encoding data in such a way that only authorized parties can access and decipher it, thus preventing unauthorized access or interception of the information. By encrypting data before transmission, even if it is intercepted along the way, it will be virtually impossible for unauthorized individuals to understand or make use of the sensitive information. This helps to protect the integrity, confidentiality, and authenticity of the data being exchanged within IoT networks.
