Cheat-Proof Trust Model for Cloud Computing Markets

چکیده
Online Reputation Systems would help mitigate the information asymmetry between clients and providers in Cloud Computing Markets. However, those systems raise two main drawbacks: the disagreement for assuming the cost of ownership of such services and their vulnerability to reputation attacks from dishonest parties that want to increase their reputation. This paper faces both problems by describing a decentralized model that would not need from the intervention of a central entity for managing it. This model includes mechanisms for allowing participants to avoid such dishonest behaviour from other peers: each client statistically analyses the external reports about providers and accordingly weights them in the overall trust calculation. The validity of the model is demonstrated through experiments for several use cases.
