Secure and privacy preserving consensus for second-order systems based on Paillier encryption

Secure and Privacy-Preserving Consensus

Consensus is fundamental for distributed systems since it underpins key functionalities of such systems ranging from distributed information fusion, decision-making, to decentralized control. In order to reach an agreement, existing consensus algorithms require each agent to exchange explicit state information with its neighbors. This leads to the disclosure of private state information, which ...

Homomorphic encryption-based secure SIFT for privacy-preserving feature extraction

Privacy has received much attention but is still largely ignored in the multimedia community. Consider a cloud computing scenario, where the server is resource-abundant and is capable of finishing the designated tasks, it is envisioned that secure media retrieval and search with privacy-preserving will be seriously treated. In view of the fact that scaleinvariant feature transform (SIFT) has be...

Order-Preserving Encryption Secure Beyond One-Wayness

Semantic-security of individual plaintext bits given the corresponding ciphertext is a fundamental notion in modern cryptography. We initiate the study of this basic problem for Order-Preserving Encryption (OPE), asking “what plaintext information can be semantically hidden by OPE encryptions?” OPE has gained much attention in recent years due to its usefulness for secure databases, and has rec...

The Death and Rebirth of Privacy-Preserving WiFi Fingerprint Localization with Paillier Encryption

Localization based on premeasured WiFi fingerprints is a popular method for indoor localization where satellite based positioning systems are unavailable. In these systems, privacy of the user’s location is lost because the location is computed by the service provider. In INFOCOM’14, Li et al. presented PriWFL, a WiFi fingerprint localization system based on additively homomorphic Paillier encr...
