  1. ZigBee Based Smart Meter Networks Aniqua Z. Baset CSCE 813 Internet Security, Spring 2014

  2. Electricity Meters Smart meter ▪ Automated reading ▪ Appliance specific usage ▪ Near real-time Conventional ▪ Manual reading ▪ Total usage AMR ▪ Automated reading ▪ Total usage

  3. Why Smart Meters? • Appliance specific real-time usage data • Energy consumption adjust • Renewable energy usage monitoring • Two way communication • Pricing notification • Load control • Power quality monitoring

  4. Smart Meter Adoption in US Number of entities reported: 81 Updated on April 1, 2014 Source: Smart Grid Investment Grant (SGIG)

  5. Smart Meter Market Forecast Source: Navigant Research

  6. Smart Meter Hacks • Reprogram through infrared ports • Widespread incidents of power thefts in Puerto Rico • laptop, an optical converter device and a free downloadable program from internet • According to FBI, former employees of the meter manufacturer and employees of the utility company were involved • Termineter • An open source hacking tool by researchers • Need physical access • Wireless???

  7. Smart Meter Network

  8. ZigBee: The Wireless Technology for Smart Meters • Global standard for control and sensor networks • Based on IEEE 802.15.4 standard • Low cost, low data rate, low power • Wireless Personal Area Networks and device-to-device networks • Mesh network, up to 216 nodes • Maintained by ZigBee Alliance • Got it name from Honeybees!

  9. ZigBee vs. Other Wireless Technologies

  10. ZigBee Protocol Stack

  11. ZigBee Applications

  12. ZigBee Smart Energy Profile • Defines commands and attributes for smart meters, home energy display devices, smart appliances and load control devices • Supports for • Network join, re-join, leave • Key establishment • Pricing • Demand response and load control • Metering • Messaging • Time synchronization • Versions 1.0, 1.1, 2, widely used 1.1

  13. ZigBee Smart Energy Home Area Network • Every SED shares a pre-configured trust center link key with ESI • Network operations are carried out using network key • Every device in the network establishes a pairwise link key with other devices Smart Energy Device Smart Energy Device

  14. Current Work • Goal: • A formal protocol analysis using automated tool • Analyzed • Network join and key establishment • Tool used • AVISPA (Automated Validation of Internet Security Protocols and Applications) • HLPSL (High Level Protocol Specification Language)

  15. Network Join role sed(S,E:agent, Ktcl:symmetric_key, JoinReq:protocol_id, SND,RCV:channel(dy)) played_by S def= local State:nat, Knwk:symmetric_key init State := 0 transition 1. State = 0 /\ RCV(start) =|> State':= 2 /\ SND({S.JoinReq}_Ktcl) 2. State = 2 /\ RCV({Knwk'}_Ktcl) =|> State':= 4 end role role esi(E:agent, Knwk,Ktcl:symmetric_key, JoinReq:protocol_id, SND,RCV:channel(dy)) played_by E def= local State:nat,S:agent init State := 1 transition 1. State = 1 /\ RCV({S'.JoinReq}_Ktcl) =|> State':= 3 /\ SND({Knwk}_Ktcl) /\ secret(Knwk,network_key,{S,E}) end role

  16. Key Establishment

  17. Key Establishment: AVISPA Attack Trace

  18. Future Work • Practicality analysis of attack found by AVISPA • AVISPA is not so expressive, analysis using other tool • Analysis of other processes from ZigBee Smart Energy Profile

  19. Any Question ??
