Privacy-preserving smart metering
Alfredo Rial,George Danezis +1 more
TL;DR: This work proposes a privacy-preserving protocol for general calculations on fine-grained meter readings, while keeping the use of tamper evident meters to a strict minimum, and allows users to perform and prove the correctness of computations based on readings on their own devices.

Blind and Anonymous Identity-Based Encryption and Authorised Private Searches on Public Key Encrypted Data
TL;DR: A searchable encryption scheme that allows users to privately search by keywords on encrypted data in a public key setting and decrypt the search results and applies it to build apublic key encrypted database that permits authorised private searches, i.e., neither the keywords nor the searchresults are revealed.

PrETP: privacy-preserving electronic toll pricing
Josep Balasch,Alfredo Rial,Carmela Troncoso,Bart Preneel,Ingrid Verbauwhede,Christophe Geuens +5 more
TL;DR: This work presents PrETP, a privacy-preserving ETP system in which on-board units can prove that they use genuine data and perform correct operations while disclosing the minimum amount of location data.

Differentially private billing with rebates
TL;DR: In this paper, the monetary amount a customer should add to their bill in order to provably hide their activities, within the differential privacy framework, is studied, and a cryptographic protocol for oblivious billing that ensures any additional expenditure, aimed at protecting privacy, can be tracked and reclaimed in the future, thus minimising its cost.
