Santa Clara 2008 ZigBee ZSE Certification ZigBee Alliance announced first Smart Energy Profile products – Vendors from around the world – Diverse set of devices Smooths path to mainstream ZigBee HAN deployments – Solidifies ZigBee’s leadership as HAN technology of choice – Demonstrates strong momentum FOR IMMEDIATE RELEASE FIRST CERTIFIED ZIGBEE SMART ENERGY PRODUCTS ANNOUNCED Products Deliver the Final Connection Points of Smart Grids to Consumers San Ramon, Calif. – May 19, 2008 – The ZigBee Alliance, a global ecosystem of companies creating wireless solutions for use in energy management, commercial and consumer applications, today announced the official certification of products using the ZigBee® Smart Energy public application profile. This first group of products provides a broad range of services designed to help utility companies worldwide implement new home area networks for managing energy, helps consumers improve their own energy efficiency and delivers multi-vendor product interoperability.

Santa Clara 2008 How ZigBee Smart Energy Works 1)HAN devices join utility network ESP (trust center) & device authenticates using certificates Application-level link keys used between ESP & device 2)Demand Response events Utility sends DR event to ESP ESP forwards to DR device, which opts ‘in’ or ‘out’ based on consumer 3)Load Control events Utility sends DR event to ESP ESP forwards to LC device(s) 4)Pricing messages Unsecured messages to any device Utility AMI Network ZigBee HAN Programmable Communicating Thermostat (PCT) Energy Services Portal (Electric Meter or Gateway) HVAC System Load Control Device In-Home Display

Santa Clara 2008 ZSE Security and Authentication Security is critical utility requirement – Smart meter must have secure communications for safe smart grid – HAN devices & meters must have strong authentication to assure authorized devices and use Mature technology assures authentic, compliant & interoperable devices – Provides implicit certificates used to authenticate each meter or HAN device – Enable communication of unique keys per device for use with ZigBee AES encryption
