Internet of Things, Part III: Encryption slows down HomeKit use

Submitted by acohill on Thu, 07/23/2015 - 07:52

Vendors who want to roll out home security devices using Apple's HomeKit are complaining. Using the HomeKit API allows customers to control the devices (with many more applications than home security) from their iPhone or iPad.

Apple is requiring a very high level of encryption for HomeKit-enabled devices to prevent hackers from taking over these devices. If the HomeKit-enabled device controls your front door lock or the entire house alarm system, a complex encryption algorithm is a good idea.

The problem is that the very low power "smart" devices have limited processing power to handle the complex encryption, so there is a time lag between the time you send a command or query from your iPhone and the time you get a response. These things are normal developmental problems, but I find it ironic (though not surprising) that home security vendors are blaming Apple for making sure the vendor devices are safe and secure.
