Thanks to the widespread deployment of TLS, users can access private data over channels
with end-to-end confidentiality and integrity. What they cannot do, however, is prove to third …

Blockchain technologies recently received a considerable amount of attention. While the
initial focus was mainly on the use of blockchains in the context of cryptocurrencies such as …

Publish/subscribe services have encountered considerable success in the building of
modern large-scale mission-critical systems. Such systems are characterized by several non …

We construct the first homomorphic signature scheme that is capable of evaluating
multivariate polynomials on signed data. Given the public key and a signed data set, there is …

A chameleon-hash function is a hash function that involves a trapdoor the knowledge of
which allows one to find arbitrary collisions in the domain of the function. In this paper, we …

In this paper, we present the first inner-product encryption (IPE) schemes that are
unbounded in the sense that the public parameters do not impose additional limitations on …

We propose a linearly homomorphic signature scheme that authenticates vector subspaces
of a given ambient space. Our system has several novel properties not found in previous …

Applying consortium blockchain as a trust layer for heterogeneous industrial Internet-of-
Things devices is cost-effective. However, with an increase in computing power, some …

In tandem with recent progress on computing on encrypted data via fully homomorphic
encryption, we present a framework for computing on authenticated data via the notion of …

The Internet of Things (IoT) provides a platform for the interconnection of a plethora of smart
objects. It has been widely accepted for providing Information and Communication …
