摘要:
访问控制是保障秘密信息免受非法访问及获取的关键技术之一，基于信任机制的访问控制是其常用的方法。鉴于堆结构具有较快的收敛速度，能高效地反馈信息，以及贝叶斯算法能够有效地预测未知访问者的可靠度和信任度，提出基于堆结构的多域间访问控制模型。通过改进贝叶斯算法，建立一种更加准确的信任度预测方法。将堆结构和改进的贝叶斯算法相结合，建立基于堆结构的信任体制。通过堆的性质及固有的计算效率，以及贝叶斯信任度预测算法的准确性，提高信任度的收敛速度及准确度。依据信任度的可靠性，快速、有效地约束域间资源访问，以实现域间访问控制的目的。实验结果表明，与相关技术相比，提出的方案具有高效性和较高的准确率。
Abstract:
Access control is one of the key technologies to protect confidential information from unauthorized access and stealing．Trust－based access control is a common approach．In consideration of the heap structure with fast convergence speed and efficient information feedback，and the Bayesian algorithm which can effectively predict the reliability and trust of unknown visitors，in this paper we propose a heap－based access control model of multi－domain．We improve the Bayesian algorithm and establish a more accurate trust forecasting．Then combinedboth heap structure and the improved Bayesian algorithm，a trust system based on heap structure is constructed．For the nature of the heap and its inherent computational efficiency，as well as the accuracy of the Bayesian trust degree prediction algorithm，the convergence speed and accuracy of the trust degree are improved．According to the reliability，it can be fast and effective constraint of resource access between different domains，to achieve the purpose of inter－domain access control．Experiment shows that the proposed scheme is more effective and accurate compared with the related technology．
