Improved hierarchical role based access control model for cloud computing

N. N. Thilakarathne, Dilani Wickramaaarachchi

摘要:

云计算被认为是信息技术领域中最具主导性的范例之一,它提供按需的成本效益服务,如软件即服务(SAAS)、基础设施即服务(IAAS)和平台即服务(PAAS)。尽管如此,这种云计算范例仍然伴随着许多挑战,如数据安全、云服务滥用、恶意内部人员和网络攻击。在所有这些安全要求的云计算访问控制是一个基本的要求,以避免未经授权的访问系统和组织的资产。本研究的主要目的是回顾现有的云访问控制模型及其变体的优缺点,并确定进一步的相关研究方向,为公共云数据存储开发一个改进的访问控制模型。我们已经提出了详细的访问控制需求分析云计算,并确定了重要的差距,这是不能满足传统的访问控制模型。作为研究的结果,我们提出了一个改进的访问控制模型与混合密码模式和混合云架构和它的实际实现,我们已经测试了我们的模型的安全含义,性能,功能和数据完整性,以证明其有效性。我们使用AES和RSA加密算法来实现加密方案,并使用公共云和私有云来增强访问控制的安全性和可靠性。通过验证和测试,我们证明了我们的模型可以抵御真实云环境中的大多数网络攻击。因此,它已经提高了能力,与其他以前的访问控制模型,我们已经通过文献审查。

英文摘要:

Cloud computing is considered as the one of the most dominant paradigm in field of information technology which offers on demand cost effective services such as Software as a service (SAAS), Infrastructure as a service (IAAS) and Platform as a service (PAAS).Promising all these services as it is, this cloud computing paradigm still associates number of challenges such as data security, abuse of cloud services, malicious insider and cyber-attacks. Among all these security requirements of cloud computing access control is the one of the fundamental requirement in order to avoid unauthorized access to a system and organizational assets. Main purpose of this research is to review the existing methods of cloud access control models and their variants pros and cons and to identify further related research directions for developing an improved access control model for public cloud data storage. We have presented detailed access control requirement analysis for cloud computing and have identified important gaps, which are not fulfilled by conventional access control models. As the outcome of the study we have come up with an improved access control model with hybrid cryptographic schema and hybrid cloud architecture and practical implementation of it. We have tested our model for security implications, performance, functionality and data integrity to prove the validity. We have used AES and RSA cryptographic algorithms to implement the cryptographic schema and used public and private cloud to enforce our access control security and reliability.By validating and testing we have proved that our model can withstand against most of the cyber attacks in real cloud environment. Hence it has improved capabilities compared with other previous access control models that we have reviewed through literature.
