Attributes define, classify, or annotate the datum to which they are assigned. However,
traditional attribute architectures and cryptosystems are ill-equipped to provide security in …

We design an encryption scheme called Multi-dimensional Range Query over Encrypted
Data (MRQED), to address the privacy concerns related to the sharing of network audit logs …

In many everyday scenarios, sensitive information must be shared between parties without
complete mutual trust. Private set operations are particularly useful to enable sharing …

As more corporate and private users outsource their data to cloud storage providers, recent
data breach incidents make end-to-end encryption an increasingly prominent requirement …

In two-party private set intersection (PSI), Alice holds a set X, Bob holds a set Y, and they
learn (only) the contents of X∩ Y. We introduce structure-aware PSI protocols, which take …

We introduce a new form of encryption that we name matchmaking encryption (ME). Using
ME, sender S and receiver R (each with its own attributes) can both specify policies the other …

Ateniese et al. introduced the primitive of matchmaking encryption (ME) at CRYPTO 2019
and left open several important questions, which include extending ME to fuzzy cases or …

Automatic service discovery is essential to realizing the full potential of the Internet of Things
(IoT). While discovery protocols like Multicast DNS, Apple AirDrop, and Bluetooth Low …

Proximity-based mobile social networking (PMSN) refers to the social interaction among
physically proximate mobile users. The first step toward effective PMSN is for mobile users to …

Abstract We present efficient Identity-Based Encryption (IBE) and signature schemes under
the Symmetric External Diffie-Hellman (SXDH) assumption in bilinear groups. In both the IBE …
