• Slow to Market HomeKit Compatible Accessories Attributed to Demanding Encryption



    According to a recent report from Forbes, the slow-trickle of HomeKit-compatible accessories is reportedly linked to a high level of encryption mandated by Apple. As of right now, encryption standards require that accessories use 3,072-bit keys and Curve25519, an elliptic curve for signatures and key exchange. While this is manageable for devices that communicate with one another via Wi-Fi, ones using Bluetooth Low Energy (LE) are said to be running into several processing barriers.

    An Elgato spokesman commented that one Bluetooth-based sensor it had in development was initially taking up to 40 seconds to determine if a door was open or closed. An anonymous source at another company meanwhile claimed that the lag ended up reaching up to 7 minutes on a device. The second person remarked that various makers of Bluetooth LE chips, such as Marvell and Broadcom, are working to improve their designs to handle Apple’s encryption demands. Even Apple is allegedly aware of the lag problem.

    While the fix is being worked on, Elgato is coping via optimized firmware and extra onboard memory. The company is even planning on selling its workarounds to other accessory makers. Up until now, the company is the only HomeKit accessory maker with Bluetooth products.

    The lag isn’t the only issue that is causing HomeKit development issues. Sources are saying that the HomeKit code wasn’t at a level for MFi (Made for iPhone/iPod/iPad) certification until two months ago. Apple is reportedly insisting that every change to a product has to be resubmitted. That being said, this issue is relatively normal for the MFi program.

    We’ll have to wait and see how the issue gets resolved by being patient.
