What is the primary purpose of encryption in IoT communications?

Encryption in IoT is all about protecting the privacy of information by making data unreadable to anyone who isn’t authorized. In IoT, data often travels across networks and is stored on devices or in the cloud. When data is encrypted, even if someone eavesdrops on the network or gains access to stored data, they can’t understand its contents without the correct keys. This shields sensitive telemetry, commands, and user data from prying eyes and helps meet privacy and security requirements for both in-transit and at-rest data. That’s why the option about protecting data in transit and at rest is the best fit. Encryption doesn’t speed up data transfer and can add some processing overhead, which is why other choices about faster transfers or lighter battery use aren’t accurate. It also doesn’t inherently simplify development; it introduces considerations like key management and secure implementation.
