The Z-Wave Alliance has adding a security requirement to its long-standing interoperability certification. This addition to its certification program will require manufacturers to adopt the strongest levels of IoT security in the industry. The Alliance Board of Directors has voted to make the implementation of the new Security 2 (S2) framework mandatory for all products that are Z-Wave certified after April 2, 2017. The security measures in S2 provide the most advanced security for smart home devices and controllers, gateways and hubs in the market today.
The Z-Wave Alliance, along with its Board of Directors and members, have been working for the past several years to develop world-class security for its devices as the IoT expands into every modern household in the U.S. and across the globe. A 2016 survey by Intel Security(1) showed that two-thirds of consumers are worried about cybersecurity of connected devices and recent incidents involving popular brands demonstrates the real need for industry leadership.
Z-Wave’s S2 framework was developed in conjunction with cybersecurity hacking experts, giving the already secure Z-Wave devices, new levels of impenetrability. By securing communication both locally for home-based devices and in the hub or gateway for cloud functions, S2 also completely removes the risk of devices being hacked while they are included in the network. By using a QR or pin-code on the device itself the devices are uniquely authenticated to the network as well. Common hacks such as man in the middle and brute force are virtually powerless against the S2 framework through the implementation of the industry-wide accepted secure key exchange using Elliptic Curve Diffie-Hellman (ECDH). Finally, Z-Wave also strengthened its cloud communication, enabling the tunnelling of all Z-Wave over IP (Z/IP) traffic through a secure TLS 1.1 tunnel, removing vulnerability.
The changes to Z-Wave’s technical certification program, which is administered through 3rdparty test facilities in Europe, US and Asia, first established to test and certify Z-Wave devices in 2005 will check that all S2 security solutions, which contain rules for command classes, timers and device types are correctly implemented.
