Integrating Cloud Platforms to Identity Federations

Privacy of the data processed and/or stored in the cloud is a concern for the users of these services. Cloud platforms are exposed in the Internet, managed by third parties, and their usage is shared by different users. Identity and access control mechanisms are relevant because they intend to protect data from improper access. Among these mechanisms, identity federations let users´ authentication be performed by entities that are closer to them. The proposal of this work is to integrate the Open stack cloud platform to identity federations using SAML and OpenID Connect protocols. These protocols are compared observing the ease of integration and performance.
