Analysis

  • Security Analysis

– Secure versus most of the TRM attacks

  • Implementation tip

– Role of – CSC interests

  • Applicability:

– Affect of the target price

Conclusion

  • Maximizing the trust and Minimizing the cost.
  • We formulated the problem in a multi layer chain of CSPs.
  • Proposed an efficient and practical TRM framework
  • It dynamically can be adapted to the service and

countermeasures that are required by the CSC.

  • Our analysis showed that our system is secure to be used

and reliable in cloud.

  • To extend: Adding cost minimization approaches; designing

FnT(.); using this system to reduce the influence of the CSP with low trust value in order to have less impact on the trust value of the chain.
