Hysteresis-based robust trust computing mechanism for cloud computing
Published 2012“…Researchers have proposed several trust computing mechanisms based on different techniques and trust metrics on the literature.Almost all of these mechanisms increment or decrement the trust scores monotonously based on the inputs.This is a major vulnerability that can be exploited by adversaries to force the trust scores towards extreme values.In this paper, the authors propose a novel trust computing mechanism based on hysteresis function which requires extra efforts to force the output from one end to the other.Hysteresis functions are immune to small changes and hence can be used to protect the system from sporadic attacks.The proposed mechanism has been tested using simulations.The test results show that the trust scores computed using the proposed mechanism are more robust and stable in the face of attacks than other mechanisms.…”

Robust multi-dimensional trust computing mechanism for cloud computing
Published 2014“…Cloud computing has become the most promising way of purchasing computing resources over the Internet.The main advantage of .cloud computing is its economic advantages over the traditional computing resource provisioning.For cloud computing to become acceptable to wider audience, it is necessary to maintain the quality of service (QoS) commitments specified in the service level agreement.In this paper, the authors propose a robust multi-level trust computing mechanism that can be used to track the performance of cloud systems using multiple QoS attributes.In addition, tests carried out show that the proposed mechanism is more robust than the ones published in the literature.…”

Statistically controlled robust trust computing mechanism for cloud computing
Published 2014“…Quality of service plays an important role in making distributed systems.Users prefer service providers who meet the commitments specified in the Service Level Agreements to these who violate them.Cloud computing has been the recent entrant to the distributed system market and has revolutionized it by transforming the way the resources are accessed and paid for.Users can access cloud services including hardware, development platform and applications and pay only for the usage similar to the other utilities. Trust computing mechanisms can play an important role in identifying the right service providers who would meet the commitments specified in the Service Level Agreements.Literature has reported several trust computing mechanisms for different distributed systems based on various algorithms and functions.Almost all of them modify the trust scores monotonously even for momentary performance deviations that are reported.This paper proposes a trust computing mechanism that statistically validates the attribute monitored before modifying the trust scores using a hysteresis based algorithm.Hence the proposed mechanism can protect the trust scores from changes due to momentary fluctuations in system performances.The experiments conducted show that the trust scores computed using the proposed mechanism are more representative of the long-term system performance than the ones that were computed without the validation of the inputs.…”
