1 The Introduction of Sensor-Cloud and Its Architecture, Applications and Approaches Mao-Lin Li 2013/11/5

2 What is a Sensor-Cloud? Sensors: Limited and are specific to their applications/services when linked very closely to them. Clouds: Computation power, scalarbility...

3 The Concept of Sensor-Cloud A new paradigm for cloud computing that uses the physical sensors to accumulates its data and transmit all sensor data into a cloud computing infrastructure.

4 Service instance: virtual sensors Created by service templates IT resources: CPU, disk storage

5

6 Why we need Sensor-Cloud? Some featured cannot be obtained by normal tools Highly sensitive data Structured health and envirment based monitoring Data scalability, performance, programmability or accessibility.

7 Advantages of Sensor Cloud Handling huge data Analyze Resource optimization Visualiztion Scalability Collaboration Impoving acceesiblity Quick Response Sensor-Cloud Agility of services Free provisioning of increased data storage and processing power Dynamic provisioning of services Save money Reduced cost and higher gain Multi-tenancy Flexibility Automation

8 Service Creation and Renovation Capability in Several Applications Telematics Ubiquitous Healthcare Environmental Monitoring for emergency/disaster detection Microsoft Health-Vault Google Health Earth Observation Transportation and Vehicular Traffic Applications Agriculture and irrigation Control (Field server sensors)

9 Sensor-Cloud as Layered Structured Approach 1. User and Application Phase Deals with the users and their relevant applications. 2. Sensor Cloud and Virtualization Phase Deals with virtualization of the physical sensors. 3. Template Creation and Tangible Sensors Phase Copes with the service templaate creation and service catalog definition phase in form of catalog menu.

10 Multi-Service Provisioning on Multiple Platform XML standard data exchange format. Metadata: Type Specification Accurancy of intensity Exact location

11 Cloud-Sensor for Health Monitoring Applications

12 Issues and Challenges Designing issues Engineering issues Power issues Reliability issues Security and privacy support issues

13 Formal Modeling for MultiLevel Authentication in Snesor-Cloud Integration System

14 Motivation Presenting an authentication system by employing the multi-level authentication technique in securing the sensor data in cloud. Modeled the proposed system using Petrinets

15 Multilevel Authentication Technique for Securing Sensor Data Cloud Service Development Activities Cloud Service Provider SaaS PaaS IaaS DSaaS Authenticated organization in using cloud services SA = Generate Multidimensional Service Authentication Password Within Organization TA = Generate Multidimensional Team Authentication Password PA = Generate Multidimensional User Private Authentication Password = Concatenating(SA, TA, PA) Super Privileged User Special Privileged User Normal User

16 System Architecture WSN Type1 BS Cloud Service Development Activities Cloud Service Provider gateway Saa S Paa S DSa as IaaS Authenticated organization in using cloud services SA = Generate Multidimensional Service Authentication Password Within Organization BS gateway TA = Generate Multidimensional Team Authentication Password gateway PA = Generate Multidimensional User Private Authentication Password = Concatenating(SA, TA, PA) WSN Type2 Super Privileg ed User Special Privileg ed User Normal User

17 Proposed Algorithm T PW = Concatencate L0, L1 Ln If PA is authenticated Sensors would process & route the data packets to CH PA - User level PW generation Authentication at level n If PW is authenticated F F T T F CH collects data packets and route it to the BS If TA is authenticated TA - Team level PW generation Authentication at level 1 The routed data would be collected by the BS and upload the information to the CS CS acts as a repository to store the info & provides access only to authenticated users T If SA is authenticated SA - Organization level PW generation Authentication at level 0 Abort Provide access to the sensor F End CH - Cluster head BS - Base station CS - Cloud server SA - Service authentication TA - Team authentication PA - Privilege authentication

18 System Modeling with Petri-Net

19 Conclusion The sensor-cloud architecture enables the data to be categorized, stored and processed in such a way that it becomes cost effective, timely available and easily accessible. A formal modeling approach to decribe authentication in sensor-cloud.
