3. Cloud Computing - Evolution
 Mainframe Computing - many users shared powerful
mainframes using dummy terminals.
 PC Computing - stand-alone PCs became powerful
enough to meet the majority of users’ needs.
 Network Computing - PCs, laptops, and servers were
connected together through local networks to
share resources and increase performance.

4. Cloud Computing - Evolution
 Internet Computing - local networks were connected
to other local networks forming a global network
such as the Internet to utilize remote applications
and resources.
 Grid Computing - provided shared computing power
and storage through a distributed computing system.
 Cloud Computing - further provides shared resources
on the Internet in a scalable and simple way.

5. Cloud Computing
Common Location-independent Online Utility on Demand
Common : implies multi-tenancy,
not single or isolated tenancy
Utility : implies pay-for-use
on Demand : implies infinite, immediate,
invisible scalability

6. Cloud Computing
 Latest distributed computing model.
 Implements the utility computing vision.
 On-demand, pay-as-you-go, and utility computing.
 A ubiquitous network access.
 Objective - To increase the capacity and capabilities
of client devices by accessing leased infrastructure
and software applications instead of owning them.

7. Cloud Computing - Services
A Few Services of Cloud:
 SaaS - to use on demand software that is
provided by the service provider via a thin client
device for consumers
 PaaS - applications deployed without the burden
and cost of buying and managing the hardware and
software for customers
 IaaS - outsourcing of responsibility of equipment
 MaaS, CaaS, LaaS, XaaS

8. Mobile Cloud Computing
A new distributed computing paradigm for
mobile applications whereby the storage and
the data processing are migrated from the
mobiles to resources rich and powerful
centralized computing data centers in
computational clouds.
Aepona, “White paper, Mobile Cloud Computing
Solution Brief”, November 2010.

9. Mobile Cloud Computing - Features
 In MCC, these are Transferred to cloud
 Intensive computing
 Data storage
 Information processing
 Ubiquity and Mobility are two major features in next
generation network.

10. Mobile Cloud Computing - Architecture

11. Mobile Cloud Computing -Characteristics
 Scalability
 Agility
 Reliability
 Security
 Reduced Cost
 Reduced Maintenance

12. Mobile Cloud Computing - Challenges
 Limitation of bandwidth and communication latency
 Signal Disturbance
 Security
 Limited power, memory, screen, OS
 Low computing ability – Processing power
 Quality of Service (affected by landforms, weather
and buildings)

13. Mobile Cloud Computing - Challenges
Limitations in contrast with PCs and Laptops
 3 times less in processing capacity
 8 times less in memory
 5 to 10 times less in storage capacity
 10 times less in network bandwidth

14. Mobile Cloud Computing –Security Layers
Security Services are in three layers
 Backbone layer – security surveillance in cloud
physical system
 Infrastructure layer – monitors VMs in cloud,
storage verification, Evaluation and Audits, …
 Application and Platform layer – user management,
key management, authentication, authorization,
encryption and data integration.
Recent survey – 73% of IT executives and CEOs are
unwilling to adopt cloud services due to privacy and
security

15. Mobile Cloud Computing –Security Issues
Security Issues in MCC
 Data Ownership
 Privacy
 Data Security
 Other security issues

16. Mobile Cloud Computing –Security Issues
Security Issues in MCC
 Data Ownership – MCC provides the facility to store
personal data and other data (purchases)
who owns the data?
users need to be aware of different rights on
purchases (Audio, Video, …).
 Privacy – one of the biggest challenge
Some apps store user’s data remotely, which may be
sold to others (agencies ...) without the permissions
of user. ( like updates about Location).

17. Mobile Cloud Computing –Security Issues
 Data Security and Other security issues – Mobiles
are famous for malicious code – gives possibility of
loss.
 Data loss from lost/stolen devices
 Info stealing by malicious malware
 Data leakage due to poorly written third party app
 Unassured network access, unreliable APs
 Insecure Market places
 Near Field Communication and Proximity based
hacking

18. Mobile Cloud – Existing Solutions
 Anand Surendra – Secure framework to store data in
secured fashion to protect user’s privacy.
 Jibitesh Mishra – Secure architecture to maintain
integrity and security of data.
 Itani et. al – an energy efficient framework to assure
user’s integrity.
 Jon Oberheide – architecture with three components
 Host Agent – lightweight process on device
 Network Service – analyses what is sent by host
 Cache - Global Shared & Local Private cache

19. Mobile Cloud – Existing Solutions
 Chetan et. al – wildcat prevention and protection
 Cloud access protection – OTP, OpAuTH
 Embedded device identity protection –
personalized profile on each device.
 Marinelli – Hyrax, a MCC platform from Hadoop
 Offers sane performance in data sharing
 Allows users to utilize data and computing
process on networks

20. Mobile Cloud – Possible Solutions
Some steps for winning battle of breaches:
 Prioritize the objectives and set the risk
tolerance
 there is no 100% secure.
 Harddecisions on different levels of protection.
 Protect data with proactive security plan
 A plan with threat landscape in mind (hacking
cyber crime, media & social scams, etc…)
 With policies and technologies.

21. Mobile Cloud – Possible Solutions
Some steps for winning battle of breaches:
 Prepare the response to inevitable sophisticated
attacks
 Advanced continual threats need to be
encountered.
 Unified and tested response plan is needed.
 Promote the culture of security awareness
 Careless mistakes of individuals (an employee
could affect master plan of CEO).
 Build data security on culture of organization.

22. Conclusion
 To attain more security and increase reliability
 Threats need to be addressed & studied
 Data security plan needs to be developed.
 It is essential to keep in mind in designing a
framework for MCC
 More cost effective
 More energy efficient
 Better security
 Better performance
