摘要：Multi Agent System (MAS) is a collection of an agents that work together to achieve a goal through communication and collaboration among each other. MASs are often distributed and agent has proactive and reactive features which are very useful. Cloud computing moves the application software and databases to the large data centers or Cloud Data Storages (CDSs), where the management of the data and services may not be fully trustworthy. Considering that the data is distributed, updated, created through different sources. This unique attribute however, poses many new security challenges which have not been well understood. To ensure the confidentiality, correctness assurance, availability and integrity of users’ data in the cloud, a security framework based on MAS architecture is proposed. This prototype is named as GSecaaS (Ganawa Security as a Service), this prototype tends to use specialized autonomous agents for specific services and allows agents to interact. The proposed MAS architecture includes five types of agents: Cloud Service Provider Agent (CSPA), Cloud Data Confidentially Agent (CDConA), Cloud Data Correctness Agent (CDCorA), Cloud Data Availability Agent (CDAA) and Cloud Data Integrity Agent (CDIA). To simulate the Agents, Oracle database packages and triggers are used to implement agent functions and Oracle jobs are utilized to create Agents. Each agent is considered as an instance of the agent in the environment that can work independently and can communicate with other agents in order to fulfill its needs or fulfill the others requests. Rasch software is used to analyze the data.
