A Hybrid Approach for Highly Available and Secure Storage of Pseudo-SSO Credentials

  • Jan Zibuschka

Part of the Lecture Notes in Computer Science book series (LNCS, volume 7617)


We present a novel approach for password/credential storage in Pseudo-SSO scenarios based on a hybrid password hashing/password syncing approach that is directly applicable to the contemporary Web. The approach supports passwords without requiring modification of the server side and thus is immediately useful; however, it may still prove useful for storing more advanced credentials in future SSO and identity management scenarios, and offers a high password security, high availability and integration of secure elements while providing familiar interaction paradigms at a low cost.
