The Internet of Things (IoT, sometimes Internet of Everything) is the network of physical objects or "things" embedded with electronics, software, sensors, and connectivity to enable objects to exchange data with the production, operator and/or other connected devices based on the infrastructure of International Telecommunication Union's Global Standards Initiative. The Internet of Things allows objects to be sensed and controlled remotely across existing network infrastructure, creating opportunities for more direct integration between the physical world and computer-based systems, and resulting in improved efficiency, accuracy and economic benefit. Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Experts estimate that the IoT will consist of almost 50 billion objects by 2020.

(Source: https://en.wikipedia.org/wiki/Internet_of_Things)

The Internet of Things (IoT) is a scenario in which objects, animals or people are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. IoT has evolved from the convergence of wireless technologies, micro-electromechanical systems (MEMS) and the Internet.

Benefits of Wireless Mesh for Field Area Networks

16

• In 2008 there were no wireless communications standards for Peer to Peer Field Area Networks

• There were a number of proprietary Field Area Network solutions; many were based on a common technology

A standard was needed - IEEE802.15.4g

Standards Development The Need for IEEE 802.15.4g


• Focus on Smart Utility Network Communication

• Optimise for Large Scale outdoor Wireless Mesh Networks – “Field Area Network”

• To take proven technology and create a standard to allow interoperable products to address global market.

Standards Development IEEE 802.15.4g - Scope


• May / July 2008 – Interest Group Meetings

• September 2008 – Study Group formed

• November 2008 – PAR was approved

• January 2009 – First meeting of 802.15 TG4g

• March 2010 – First Letter Ballot

• August 2011 – First Sponsor Ballot

• March 2012 – Approved by IEEE Standards Board


Standards Development IEEE 802.15.4g - Timeline

19

IEEE 802.15.4g Participation

• Contributors included: – International representation from Gas and Electric utilities

– 8 Smart Grid equipment vendors

– 8 RF silicon vendors

– Government organizations


• Positive features and outcomes – Proven Technology

– Backward compatibility with installed base of 10’s millions of meters.

– Great flexibility • Multiple data rates

• Robust error detection

• Optional forward error correction

• Large frame sizes supporting IP directly

– Support for Global and Regional frequency bands • 902-928 MHz in North and South America plus many other regions

• 920 MHz in Japan

• 868.3 MHz in Europe

• Easily extended to other frequency bands


IEEE 802.15.4g feature summary

21

• There are a wide range of requirements across different Smart Utility Applications, e.g. :

– Advanced Metering Infrastructure

– Demand/Response

– Distribution Automation

– Smart City – e.g. Street Lighting

– Low power Meter reading – e.g. Gas Metering

– Home Energy Management Systems

– Agricultural

• These applications have a variety of communication requirements

• Communication “profiles” support these application needs


Supported Applications

22

• Many different stakeholders

• Process results in standards which include many options and features

• Standards can be too generic to implement –

– more options increases the problems in achieving interoperability

• A great start, but …


Standards Development Risks

23

The need for “Profiles”


• Specifying the communications functionality for each Smart Utility Network Application

– Options add complexity and make interoperability more difficult to verify.

• An Industry Alliance provides the forum …

– to focus on commercial applications

– to specify a complete protocol stack from PHY to transport layer.

– to specify appropriate security protocols for the application

– To create and manage a testing and certification program

– (many SSOs/SDOs including IEEE802, IETF do not define testing)


What was still needed?

• Standards support great flexibility

• Flexibility provides opportunity to support different application requirements, but…

• needs restricting to improve interoperability in each specific application

• Wi-SUN Alliance identifies functionality required for each application area

• Creates “Profile” of standard(s) to meet functional requirements

• Creates Test Plan to verify product compliance with the profile

• A Wi-SUN Alliance approved test laboratory verifies

• (a) Product conformance with “Profile”, and

• (b) Product interoperability with other conformant products

• Wi-SUN Alliance certifies the Product


Wi-SUN Alliance Role

• Wi-SUN Alliance develops Technical Profile specifications of Physical Layer (PHY) and Medium Access Control (MAC) layers, and Network/Transport layer as required.

• Develop test programs to ensure implementations are interoperable

• Wi-SUN Physical layer specification is based on IEEE802.15.4g

• Profile specifications are categorized based on Application

• Each layer may use different options depending on the application (Home Energy Management, Field Area Network ... ).

Security Considerations for Wireless Networks


• Security Concerns – Loss of confidentiality: the unauthorized disclosure of information;

– Loss of integrity: the unauthorized modification or destruction of information

– Loss of availability: the disruption of access to or use of information or an information system.

• Challenges – Wireless Networks are easily overheard

– IoT devices are often constrained, e.g. limited resources, limited energy

• NISTIR 7628 – defines “Guidelines for Smart Grid Cyber Security”

– A comprehensive analysis including, use cases and threats, algorithms, key management etc


Security Concerns and Challenges

30

• Passive – Eavesdropping: an attacker intercepts packets transmitted over the air for further

cryptanalysis or traffic analysis.

– Traffic analysis: allows an attacker to determine that there is activity in the network, the location of the BSs, and the type of protocols being used.

– Message injection: an adversary injects bogus control information into the data stream.

• Active – Message modification: a previously captured message is modified before being

retransmitted

– Node capture: An embedded device is considered being compromised when an attacker, through various means, gains control of the node itself. (includes tampering)

– Denial-of-Service (DoS) attacks: can be grouped into two categories

• Service degradation (e.g. collision attack), and

• Service disablement (e.g. jamming)

(Source: IN3-UOC 2014 seminar by Prof. A.A. Economides)


Security – Attack Models

31

• Choose Security Appropriate for Implementation

• Key Management – Device Authentication

– Secure session key exchange

• Layer 2 security is good for Wireless IoT Networks – Hardware support

– Restricted access to network

– All network traffic is secured

• Layer 2 security Mechanisms – L2 Encryption, ensures message confidentiality

– L2 Integrity Check / Authentication, ensures message integrity

– Decentralised Frequency Hopping mitigates against interferers, either intentional or accidental which improves Network availability

– Networks may use group keys and/or pairwise keys.

• Application Layer security is Out of Scope for Wi-SUN Alliance
