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
satisfy the requirements of different application scenarios. With an established trust
relation in MT-UCON (Multi-tenant Usage Access Control), the trustee can precisely
authorize cross-tenant accesses to the trustor’s resources consistent with constraints over
the trust relation and other components designated by the trustor. In addition, the security
of the model is analyzed by an information flow method. The model adapts to the
characteristics of a dynamic and open multi-tenant cloud computing environment and
achieves fine-grained access control within and between tenants.
