Efficient Mutual Authentication for Multi-domain RFID Systems Using Distributed Signatures [chapter]

Michael Braun, Ulrike Meyer, Susanne Wetzel
2010 Lecture Notes in Computer Science  
In this paper, we propose a new public-key-based mutual authentication protocol that addresses the reader revocation problem while maintaining efficiency and identity privacy.  ...  The core of our solution is the use of the concepts of key-splitting and distributed signatures to solve the validation and revocation problem.  ...  The protocol roughly works as follows: Upon receiving the public Diffie-Hellman component from the tag, the reader signs both its public Diffie-Hellman component and that of the tag using its public key  ...
