Constrained shortest distance (CSD) querying is one of the fundamental graph query
primitives, which finds the shortest distance from an origin to a destination in a graph with a …

The proliferation of online biometric authentication has necessitated security requirements of
biometric templates. The existing secure biometric authentication schemes feature a server …

In this work, we examine the efficiency of protocols for secure evaluation of basic
mathematical functions (sqrt, sin, arcsin, amongst others), essential to various application …

In this paper we study verifiable sampling from probability distributions in the context of multi-
party computation. This has various applications in randomized algorithms performed …

Graph databases have received increased interests as many applications are handled as
graph problems. Shortest distance queries are one of the fundamental operations and have …

In this paper we present a new class of protocols for the secure computation of the sine and
cosine functions. The precision for the underlying secure fixed-point arithmetic is …

Collecting data about people's health contributes to useful medical research, adapting
health care programs or improving overall knowledge about us, human beings. Data is …

Model extraction attacks have been widely applied, which can normally be used to recover
confidential parameters of neural networks for multiple layers. Recently, side-channel …

In recent years, the concern for privacy has significantly grown. This is a consequence of the
regular use of data-intensive services that require the massive outsourcing and processing …

In privacy-preserving machine learning, it is less obvious to verify correct behavior of
participants because they are not supposed to reveal their inputs in cleartext to other …
