A smart lock is a lock. It keeps intruders out and our valuables in. The ‘key’ to this kind of lock differs from traditional ones. In the case of a smart lock, wireless functions and cryptographic keys work the ol’ pin and tumbler process a bit differently. Smart locks are controlled by smartphones and smart homes, which send messages to the lock via wireless communication. These devices all need to be capable of sending and receiving data to one another. It’s also important that these transactions are kept secure from involved devices.
Cryptographic keys keep the info shared between smart devices private. They keep data transmissions secure. Without these keys, the use of smart locks would be greatly compromised.
Three things happen when you tap to work a smart lock on your home. First, the transmission with the command is sent. Then, that transmission is deciphered by the receiving smart device. Finally, that data is carried through in whatever action you requested. Smart locks can be adapted to work concurrently with other smart devices, which is why they can often fit seamlessly into a smart home.
