The negotiation on Service Level Agreement (SLA) in current complex cloud environment often involves the multilateral negotiation. Therefore, this paper presents an SLA-oriented multiparty trust negotiation model based on Hierarchical Colored Petri Net (HCPN) in cloud environment. This model mainly provides trust negotiation of SLA parameters such as credibility, reliability, availability and service price so on for Cloud Service Providers (CSPs) and Cloud Service Consumers (CSCs), thus making complex process description of multiparty trust negotiation on SLA in cloud environment simple and efficient. On the basis of the HCPN model on SLA, this paper puts forward a multi-objective optimization algorithm for SLA trust negotiation. Simulation results show that the algorithm not only improves efficiency of multilateral negotiation, but also avoids QoS negotiation falling into local optimization.
