Internet of Things (IoT) allows billions of physical objects to be connected to collect and
exchange data for offering various applications, such as environmental monitoring …

Summary Internet of Things (IoT) connects different objects in the physical world to the
Internet, and various Internet protocols are used to provide communication services to a …

We put forth the problem of delegating the evaluation of a pseudorandom function (PRF) to
an untrusted proxy and introduce a novel cryptographic primitive called delegatable …

In this work, we show how to use indistinguishability obfuscation to build multiparty key
exchange, efficient broadcast encryption, and efficient traitor tracing. Our schemes enjoy …

We provide a provable-security treatment of “robust” encryption. Robustness means it is
hard to produce a ciphertext that is valid for two different users. Robustness makes explicit a …

Kyber is a key-encapsulation mechanism (KEM) that was recently selected by NIST in its
PQC standardization process; it is also the only scheme to be selected in the context of …

A core goal of the NIST PQC competition is to produce PKE schemes which, even if attacked
with a large-scale quantum computer, maintain the security guarantees needed by …

Smart grid enables two-way communications between operation centers and smart meters
to collect power consumption and achieve demand response to improve flexibility, reliability …

We use multilinear maps to provide a solution to the long-standing problem of public-key
broadcast encryption where all parameters in the system are small. In our constructions …

In the standard setting of broadcast encryption, information about the receivers is transmitted
as part of the ciphertext. In several broadcast scenarios, however, the identities of the users …
