Security in MCC
 Wireless networks often pass sensitive information
 a lot of vulnerabilities may still occur during data
transfer
 Wi-Fi via free hotspots can provide the hackers the
means to
 obtain personal data about device owners
 unauthorized access
 installing a malware or any other malicious
behavior
 All Wi-Fi hotspots are susceptible to “man in the
middle” attacks where a hacker intercepts
communications between a user and a Wi-Fi
 The interception can also occur through the Internet, by
way of tapped telephone lines or intercepted radio
transmissions.

Conclusion
 The concept of Cloud Computing provides a
new opportunity for Mobile Cloud
Computing’s development
 Since it serves as a powerful complement to
the resources-constraint nature of mobile
devices.
 However it still suffers from some issues
especially security issues.

23
Perspectives
 Proposing an approach that serves to keep the
vulnerable parts in the mobile device to be executed
and to deport the rest in a way to guarantee their
security.
 We inspired from the Centralized Organic Computing
 its architecture that is based on the principle of
observer / controller and characterized by Self-X
characteristics
 Self-Protect,
 Self-Heal,
 Self-Optimize,
 Self-Configure
 allows making decisions on the partitions that will be
deported in the Cloud and those that remain at the
mobile terminal level.
