Efficient, secure, private distance bounding without key updates
2013
Proceedings of the sixth ACM conference on Security and privacy in wireless and mobile networks - WiSec '13
Preserved Fulltext
We propose a new distance bounding protocol, which builds upon the private RFID authentication protocol by Peeters and Hermans [25] . ...
In contrast to most distance-bounding protocols in literature, our construction is based on publickey cryptography. ...
We would like to thank Saartje Verheyen, without whom this paper would not have been possible. ...

For secure location proof in many applications, distance bounding protocols are considered as one of the useful tools that can be used in practice. ...
To handle the security problem, a prover-anonymous and deniable distance bounding protocol is proposed, which can guarantee the privacy of the prover even though the verifier is corrupted. ...
Conclusions In this paper, we review the efficiency of the prover-anonymous and deniable distance bounding protocol. ...

We leverage the derived statistical bounds in zero-knowledge proofs to detect and remove malicious updates without revealing the private user updates. ...
However, keeping the individual updates private allows malicious users to perform Byzantine attacks and degrade the model accuracy without being detected. ...
We circumvent this challenge by forming clusters of users, where our secure aggregation can be used to efficiently compute the average of their updates. ...
