چکیده (انگلیسی):

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.
