  28. 28. Internet of Things: Definition (1) The Power of PowerPoint | thepopp.com 28 CERP-IoT: « The Internet of Things (IoT) is […] a dynamic global network infrastructure with self configuring capabilities based on standard and interoperable communication protocols where physical and virtual ‘things’ have identities, physical attributes, and virtual personalities and use intelligent interfaces, and are seamlessly integrated into the information network. In the IoT, ‘things’ are expected to become active participants in business, information and social processes where they are enabled to interact and communicate among themselves and with the environment by exchanging data and information ‘sensed’ about the environment, while reacting autonomously to the ‘real/physical world’s events »
  29. 29. Internet of Things: Definition (2) The Power of PowerPoint | thepopp.com 29  The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to- computer interaction.
  30. 30. Internet of Things: Definition (3) The Power of PowerPoint | thepopp.com 30  According to Wikipedia, IoT refers to the interconnection of uniquely identifiable embedded computing-like devices within the existing Internet infrastructure. Typically, IoT is expected to offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine communications (M2M) and covers a variety of protocols, domains, and applications. The interconnection of these embedded devices (including smart objects), is expected to usher in automation in nearly all fields, while also enabling advanced applications like a Smart Grid.
  31. 31. Internet of Things: Definition (4) The Power of PowerPoint | thepopp.com 31  Things, in the IoT, can refer to a wide variety of devices such as heart monitoring implants, bio-chip transponders on farm animals, automobiles with built-in sensors, or field operation devices that assist fire-fighters in search and rescue. Current market examples include smart thermostat systems and washer/dryers that utilize WiFi for remote monitoring.
  32. 32. Internet of Things: Definition (5) The Power of PowerPoint | thepopp.com 32  Due to the ubiquitous nature of connected objects in the IoT, an unprecedented number of devices are expected to be connected to the Internet. According to Gartner, there will be nearly 26 billion devices on the Internet of Things by 2020. ABI Research estimates that more than 30 billion devices will be wirelessly connected to the IoT by 2020. Per a recent survey and study done by Pew Research Internet Project, a large majority of the technology experts and engaged Internet users who responded. 83% agreed with the notion that the Internet/Cloud of Things and embedded and wearable computing will have widespread and beneficial effects by 2025. It is, as such, clear that the IoT will consist of a very large number of devices being connected to the Internet.
  33. 33. Internet of Things: Definition (6) The Power of PowerPoint | thepopp.com 33 ‘The Internet of Things’ is a concept originally coined and introduced by MIT, Auto-ID Center and intimately linked to RFID and electronic product code (EPC) “… all about physical items talking to each other..” Like RFID it is a concept that has attracted much rhetoric, misconception and confusion as to what it means and its implications in a social context
  34. 34. Internet of Things: Definition (7) The Power of PowerPoint | thepopp.com 34 Extending the current Internet and providing connection, communication, and inter- networking between devices and physical objects, or "Things," is a growing trend that is often referred to as the Internet of Things. “The technologies and solutions that enable integration of real world data and services into the current information networking technologies are often described under the umbrella term of the Internet of Things (IoT)”
  35. 35. The Power of PowerPoint | thepopp.com 35  Formally : a network of networks which enables to identify digital entities and physical objects  whether they are inanimate (including plants) or animate (animals and human beings) – directly and without ambiguity, via standardized electronic identification systems and wireless mobile devices, and thus make it possible to retrieve, store, transfer and process data relating to them, without discontinuity between the physical and virtual worlds” (Benghozi, Bureau, Massit-Folléa, 2008)  Conceptually : new identities for objects  “Things having identities and virtual personalities operating in smart spaces using intelligent interfaces to connect and communicate within social, environmental, and user contexts” (working group Eposs)  Technically : an extension of the Internet  naming system and reveals a convergence of digital identifiers in the sense that it is possible to identify digital information (URL website addresses for instance) and physical elements (like a pallet in a warehouse, or a sheep in a herd) in a standardized way  From the user point: a new space for innovative services

  38. 38. Overview The Power of PowerPoint | thepopp.com 38 What is a thing?  We distinguish two classes of things • Things that are computers equipped with communication interfaces. • Things that are not computers, but who are associated with computers equipped with communication interfaces. What is the identifier of a thing?  They are several proposals: • A serial number, such as an EPC code. • An IP address. • Other, for example a fix hash value, or adhoc naming scheme. Authentication  Is there a need/way to authenticate a thing? In other words is it possible and needed to prove the identity of a thing.
  39. 39. Overview The Power of PowerPoint | thepopp.com 39  Identity Protection  Things can be used to track people or objects, which are identified by a set of things. Identity protection enforces privacy by hiding things identities thanks to cryptographic means.  Communication Protocol  A thing communicates with the Internet network by various interfaces  Via MAC (OSI2) radio protocols, as defined by EPCGLOBAL  Thanks the IP protocol, in that case the thing is an IP node, and is natively plugged in the Internet Cloud.  Other, for example the Host Identity Protocol  Things to Things communications  In some cases, things communicate with other things. If identity protection is required, the associated infrastructure is complex from a cryptographic or physical point of view, because classical routing techniques can't be used.

  59. 59. The Power of PowerPoint | thepopp.com 59 Communication Technologies for IoT.  IoT connects people and things via the Internet  Uses IT analytics, cloud computing, smart devices and apps  Built on cloud computing and networks of data-gathering sensors  Delivers mobile, virtual and immediate connection  Makes everything “smart”
  60. 60. Naming and identification The Power of PowerPoint | thepopp.com 60  A well-thought-out naming architecture in order to be able to identify a smart object and to establish an access path to the object is essential.  Isolated Objects. The following three different object names have to be distinguished when we refer to the simple case of an isolated object:  Unique object identifier (UID) refers to the physical identity of a specific object.  The Electronic Product Code (EPC) of the RFID community is such a UID.  Object type name refers to a class of objects that ideally have the same properties.  Object role name. In a given use context, an object plays a specific role that is denoted by the object role name.
  61. 61. Composite object naming The Power of PowerPoint | thepopp.com 61 Composite Objects. Whenever a number of objects are integrated to form a composite object, a new whole, i.e., new object is created that has an emerging identity that goes beyond the identities of the constituent objects. The composite object resembles a new concept (see Sect. 2.2.1) that requires a new name.
  62. 62. IoT Architecture
  63. 63. IoT Architecture The Power of PowerPoint | thepopp.com 63
  64. 64. Architecture for Open IoT Services The Power of PowerPoint | thepopp.com 64
  65. 65. IoT Architecture The Power of PowerPoint | thepopp.com 65
  66. 66. 01 02 03 04 05 What are the major components of IoT? The Power of PowerPoint | thepopp.com 66 Sensors/Actuators Communication between servers or server platforms Server/Middleware Platforms Data Analytics Engines Apps (iOS, Android, Web)
  67. 67. Technological Components (some kind of layered architecture) The Power of PowerPoint | thepopp.com 67  Identification (“sensing”)  (passive, active) RFID tags  sensor networks  Communication  see discussion above  interface object/network  embed the TCP/IP stack into the devices (TinyTCP, mIP, IwIP…)?  Integration  object and service discovery  object and service cataloging  service composition/orchestration  Intelligence and Collaboration  Security and Privacy
  68. 68. Identification (“sensing”) The Power of PowerPoint | thepopp.com 68  Ultimate goal: unique/universal Id for naming and addressing individual objects i.e., to attach an ego to each object, condition to develop ego- centric applications (cf. Jacob and the Angel (Genesis))  Naming is difficult!  ONS: Object Name Service • basically, RFID tag/EPC code → URI of a description file (Object Code Mapping Service-Direct Search (OCMS-DS) • more complex Object Code Mapping Service-Reverse Search (OCMS-DS): description → EPC code(s)  Addressing is difficult!  stupid but tricky issue: RFID addresses are different from IPv6 addresses (64-96 bits vs 128 bits)  addressing moving objects is even more difficult
  69. 69. Communication The Power of PowerPoint | thepopp.com 69  From host2host to object2object  TCP is not adapted  designed for long-lasting connections while objects (like tags or sensors) exchange small pieces of data => handshake + congestion control/retransmit/recovery + flow control + buffering procedures too complex  Very heterogeneous networks and traffic  Scalability?  Quality of service?
  70. 70. Security and Privacy (1/3) 70 A definitive threat for privacy! A security nightmare! Security  IoT = a kind of unsupervised mobile/pervasive grids whose end- components are resource limited tiny objects = a security nightmare  memory segments of tags are protected by (short) password  physical attacks  Man in the Middle attacks  cryptographic techniques too CPU-intensive for low energy objects  multiple administrative domains
  71. 71. Security and Privacy (2/3) The Power of PowerPoint | thepopp.com 71 Privacy  all your life can will be traced => possible monitoring, mining, analysis  connection possible with Linked Open Data => worsen the threats  open air connections => possibility of eavesdropping  not only your digital life but also your “analogical” life  you cannot even know what is sensed about you, when it is sensed, etc. Sensors do not ask for permission (cf. video surveillance)  no “forget option”
  72. 72. Security and Privacy (3/3) The Power of PowerPoint | thepopp.com 72 Privacy (cont’d)  Basic approach (e.g. EEXCESS EU project, W3C P3P (Platform for Privacy Preference)  user defined policy  privacy proxy  negotiation protocol  anonymization/pseudomization  integration of reputation and trust mechanisms (cf. course on security and privacy)  Issues  cryptographic techniques are too complex  scalability
  73. 73. IoT vs cloud computing The Power of PowerPoint | thepopp.com 73 Smart objects that have access to the Internet can take advantage of services that are offered by the cloud The division of work between a smart object and the cloud will be determined, to a considerable degree, by privacy and energy considerations If the energy required to execute a task locally is larger than the energy required to send the task parameters to a server in the cloud, then the task is a candidate for remote processing. However, there are other aspects that influence the decision about work distribution: autonomy of the smart object, response time, reliability, and security.
  74. 74. What is IoT: Internet of Tags The Power of PowerPoint | thepopp.com 74 RFID WSN
  75. 75. RFID Tags The Power of PowerPoint | thepopp.com 75  Developed to automate the process of object identification  electronic tags (called RFID tags) can be read from a small distance by an RFID reader  An RFID reader does not require a direct line-of-sight to the RFID tag.  The RFID tag stores the unique Electronic Product Code (EPC) of the attached object.
  76. 76. The Power of PowerPoint | thepopp.com 76 RFID Tag dimensions  Since an RFID tag has to be attached to every object, the cost of an RFID tag is a major issue.  RFID tags come in various shapes and sizes and continue to decrease in size  RFID tags are implantable and implants have been approved in humans as well as animals.
  77. 77. RFID Reader The Power of PowerPoint | thepopp.com 77 The RFID reader can act as a gateway to the Internet and transmit the object identity, together with the read-time and the object location (i.e., the location of the reader) to a remote computer system that manages a large database. It is thus possible to track objects in real-time Applications: toll gates, hospitals and large organizations, public transportation systems, tracking of animals, libraries
  78. 78. WSN The Power of PowerPoint | thepopp.com 78 a sensor a microcontroller a wireless communication controller A set of sensor nodes that each contains
  79. 79. WSN node The Power of PowerPoint | thepopp.com 79 A sensor node can acquire a variety of physical, chemical, or biological signals to measure properties of its environment.

  81. 81. WSN deployment and operation The Power of PowerPoint | thepopp.com 81 a number (from few tens to millions) of sensor nodes are deployed, either systematically or randomly, in a sensor field to form an ad hoc self-organizing network The WSN collects data about the targeted phenomenon and transmits the data via an ad-hoc multi-hop communication channel to one or more base stations that can be connected to the Internet.
  82. 82. Wireless Sensor Networks (WSN) The Power of PowerPoint | thepopp.com 82 Sink node Gateway Core network e.g. Internet Gateway End-user Computer services - The networks typically run Low Power Devices - Consist of one or more sensors, could be different type of sensors (or actuators)
  83. 83. Key Open Issues of the IoT
  84. 84. IoT issues The Power of PowerPoint | thepopp.com 85 The novelty of the IoT is not in the functional capability of a smart object Novelty exists in the expected size of billions or even trillions of smart objects that bring about novel technical and societal issues that are related to size. issues are:  authentic identification of a smart object,  autonomic management and self-organization of networks of smart objects,  diagnostics and maintenance,  intrusion of privacy Safety issues  Autonomous mobile robots and self-driving cars
  85. 85. Threats The Power of PowerPoint | thepopp.com 86 internet integration Security Issues DDoS Attack DDoS attack on DYN caused internet outages across the country (https://fr.wikipedia.org/wiki/Dyn_(entreprise)). Physical/Real World Ransomeware ….
  86. 86. internet integration The Power of PowerPoint | thepopp.com 87  Guaranteeing the safety and information security of IoT-based systems is considered to be a difficult task.  Many smart objects will be protected from general Internet access by a tight firewall to avoid that an adversary can acquire control of a smart object.  The IoT should extend the interoperability of the internet to the universe of heterogeneous smart objects.  Iot must establish a uniform access pattern to things in the physical world.
  87. 87. Security Issues The Power of PowerPoint | thepopp.com 88 Many IOT devices are severely lacking in the security department. Most lack basic security, and many utilize outdated firmware. Human Error (use of default usernames and passwords). Allows hackers to quickly and easily gain access to system.
  88. 88. DDoS Attacks The Power of PowerPoint | thepopp.com 89 October 21, 2016 a large scale DDoS attack on DYN servers cause large internet outages across the United States Many of the devices in the botnet were IOT devices such as home routers and security cameras Access was gained through the use of default login credentials.
  89. 89. Ransomware The Power of PowerPoint | thepopp.com 90  Hackers use the classic approach when it comes to utilizing ransomware attacks on IOT devices (I.E. Locking the device and requiring payment to unlock).  For many devices this isn’t a big issue because IOT data is usually stored in the cloud and devices can easily be reset.  This can become an issue with medical IOT devices such as drug pumps and pacemakers.  Will typically be used for timed attacks when devices cannot be easily reset.
  90. 90. Internet of Things: Technologies and Issues The Power of PowerPoint | thepopp.com 91  Integration of multiple ICT technologies  identification and tracking technologies  sensor networks  network protocols (cf. Future Internet  autonomic, pervasive and ubiquitous computing  AI, knowledge management, semantics  Key issues:  interoperability  security/trust and privacy  low resources (=> revisit protocols and algorithms implemented in Internet and Web)  scalability
  91. 91. Social and legal issues in IoT The Power of PowerPoint | thepopp.com 92 But the life of the average citizen will also be affected by changing the relation of power between those that have access to the acquired information and can control the information and those that do not.
