Universally Composable Direct Anonymous Attestation [chapter]

Jan Camenisch, Manu Drijvers, Anja Lehmann
2016 Lecture Notes in Computer Science  
Direct Anonymous Attestation (DAA) is one of the most complex cryptographic algorithms that has been deployed in practice.  ...  In this paper, we give a comprehensive security definition for full DAA in the form of an ideal functionality in the Universal Composability model.  ...  We tackle the challenge of formally defining Direct Anonymous Attestation and provide an ideal functionality for DAA in the Universal Composability (UC) framework [12] .  ...

Charlotte: Composable Authenticated Distributed Data Structures, Technical Report [article]

Isaac Sheff, Xinwen Wang, Haobin Ni, Robbert van Renesse, Andrew C. Myers
2019 arXiv   pre-print
Together, all Charlotte blocks form a directed acyclic graph, the blockweb; all observers and applications use subgraphs of the blockweb for their own data structures.  ...  To support this composability, we define a language-independent format for Charlotte blocks and a network API for Charlotte servers.  ...  Attestations about the same blocks naturally compose: all properties of all attestations hold when all conditions are met.  ...

SGX Remote Attestation is not Sufficient [article]

Yogesh Swami
2017 IACR Cryptology ePrint Archive  
Since cryptographic protocols do not compose well [Cra96, Can00, HS11], especially when run concurrently, SGX remote attestation is only a necessary pre-condition for securely instantiating an enclave.  ...  We also provide details about how SGX uses EPID Group Signatures and report (largely negative) results about claimed anonymity guarantees.  ...  Among these, from a practical deployment perspective, Direct Anonymous Attestation [BCC04,CDL16] (DAA) is closest to EPID and also most widely deployed.  ...
