Communication in trusted networks is not absolute until their relation is expressed in a transitive manner. Formulizing trust relationships leads to score reputation of a party or an entity; these evaluations are measured with subjective trust measurement, where subjective trust is described in this paper. The trust between any two parties can be analyzed through their trust linking paths. The properties of evaluating trust on network can be offered as 1. Transitive trust 2. Parallel trust combination 3. Subjective logic. In modern communication of information technology and services, a familiar style being adopted for interaction procedures. The phenomenal growth in business-to-business forum offers people with distributed application sets that are really sensitive for processing and delivering tasks. As a result computer networks fail to meet these uncertain challenges and it degrades quality of services (QOS). Business processing through e-commerce is the recent trend that offers viable applications to customers for fulfilling their business needs. Likewise, people are influenced to use distributed e-commerce application in an enormous way without considering the risk of security as a primary challenge. Cloud computing is a considerable security path, offering services to its users by meeting minimal security needs. Cloud must offer better trusted service to their consumers by building its reputation scores. In this paper assessing of trust becomes a major objective to achieve QoS and better decision-making system in cloud computing. The entities of cloud are CSP’s, which delivers the services to consumers, provided by cloud infrastructure provider (CIP). Assessing of trust with respect to CSP and CIP can be accessed on the basis of CSP positive belief on CIP.
