Non-Interactive Private Decision Tree Evaluation
Anselme Tueno, Yordan Boev, Florian Kerschbaum
Decision trees are a powerful prediction model with many applications in statistics, data mining, and machine learning. In some settings, the model and the data to be classified ma…
Secure Computation of the kth-Ranked Element in a Star Network
Anselme Tueno, Florian Kerschbaum, Stefan Katzenbeisser +2
We consider the problem of securely computing the kth-ranked element in a sequence of n private integers distributed among n parties. The kth-ranked element (e.g., minimum, maximum…
Secure Range Queries for Multiple Users
Anselme Tueno, Florian Kerschbaum
Order-preserving encryption allows encrypting data, while still enabling efficient range queries on the encrypted data. Moreover, it does not require any change to the database man…
An Efficiently Searchable Encrypted Data Structure for Range Queries
Florian Kerschbaum, Anselme Tueno
At CCS 2015 Naveed et al. presented first attacks on efficiently searchable encryption, such as deterministic and order-preserving encryption. These plaintext guessing attacks have…
