Abstract Most cloud services are built with multi-tenancy which enables data and
configuration segregation upon shared infrastructures. It offers tremendous advantages
for enterprises and service providers. It is anticipated that this situation will evolve to
foster cross-tenant collaboration supported by Authorization as a service. To realize
access control in a multi-tenant cloud computing environment, this study proposes a
multi-tenant cloud computing access control model based on the traditional usage access
control model by building trust relations among tenants. The model consists of three submodels, which achieve trust relationships between tenants with different granularities and
