ABSTRACT: The adoption of Cloud Computing services in everyday business life has
grown rapidly in recent years due to the many benefits of this paradigm. The
various collaboration tools offered by Cloud Computing have eliminated or
reduced the notion of distance between entities of the same company or between
different organizations. This has led to an increase in the need to share
resources (data and services). Community Cloud environments have thus emerged
to facilitate interactions between organizations with identical needs and with
specific and high security requirements. However, establishing trust and secure
resource sharing relationships is a major challenge in this type of complex and
heterogeneous environment. This paper proposes a trust assessment model
(SeComTrust) based on the Zero Trust cybersecurity strategy. First, the paper
introduces a community cloud architecture subdivided into different security
domains. Second, it presents a process for selecting a trusted organization for
an exchange based on direct or recommended trust value and reputation. Finally,
a system for promoting or relegating organizations in the different security
domains is applied. Experimental results show that our model guarantees the
scalability of a community cloud with a high success rate of secure and quality
resource sharing.
