Abstract
Despite the numerous potential benefits of Open Source Cloud Computing (OSCC) in several industrial and academic-oriented environments, OSCC could be also associated with some risks. However, which a proper awareness to the cloud consumers or organisations, these risks can be clearly identify and avoided. OpenStack Swift security can provide a greater understanding of how OpenStack Swift functions and what types of security issues arise therein. In this study, a lightweight and robust cloud-based security model for OpenStack object storage within a cloud computing environment is proposed. Swift is a multi-user based model in which every owner encrypts her/his files; each owner uses different levels of cryptographic security. A reduction in the key distribution complexity in this diverse model with a variety of security based settings is critical. Note that proposed model incorporates cryptographic algorithms at the first level (authentication/authorisation) and a hash function to introduce a more secure access method for authentication and authorisation.
Highlights
A strong interaction between cloud computing and Open Source Software (OSS) has been demonstrated by the announcement of several Open Source Cloud Computing (OSCC) projects, such as OpenStack, OpenNebula, Hadoop and CloudStack (Rodriguez-Martinez et al, 2010; Hala et al, 2013; Albaroodi et al, 2013).Typically, the security of data in the could computing service providers would be the first matter to the most of the potential cloud customers
The level of privacy and the security models which implemented by different cloud platforms reflect the acceptance of the developments of several applications
The security concerns of cloud computing is investigated in this study as the primary motivation of this research and a user-trusted model to mitigate and avoid these concerns is proposed with the aid of OSS (Popovic and Hocenski, 2010; Okuhara et al, 2010; Cooper, 2013)

The security concerns of cloud computing is investigated in this study as the primary motivation of this research and a user-trusted model to mitigate and avoid these concerns is proposed with the aid of OSS (Popovic and Hocenski, 2010; Okuhara et al, 2010; Cooper, 2013) As it forms one of the major parts of this research, the object storage components of OpenStack is considered in this study. And as has been individually mentioned in the presentation of each work, enhancing the security mechanism of swift has lacked to provide comprehensiveness (Hala et al, 2013; Albaroodi et al, 2014a; 2014b) These lacks were identified to by ranging from securing the identity, access control, passwords, protecting the data, to the protecting of the authentication and authorization process.
