	abstract = {Multi-Access Edge computing represents one of the most important enabling
technologies for the Industrial Internet of Things. It allows advanced data
processing and customized service provisioning, very close to the
end-users. In the presence of many Multi-Access Edge computing
applications, however, it is fundamental to ensure effective and
privacy-preserving data dissemination at the network edge. From the
security perspective, Attribute-based Encryption and Searchable Encryption
techniques can be jointly used to achieve data confidentiality, flexible
protection against unauthorized access, and privacy-preserving data
dissemination. 
Available solutions, however, generally focus the attention on cloud-based
approaches, use edge computing to implement some of the cryptographic
tasks, and limit the investigation to single cryptographic operations.
Indeed, no works investigate the adoption of these techniques in scenarios
with multiple data producers and end-users, and fully operating at the
network edge. To bridge this gap, this work proposes a novel methodology
supporting fast and privacy-oriented data dissemination directly at the
network edge. In the considered distributed network infrastructure,
Multi-Access Edge computing applications express the interest to receive
specific data by sending Trapdoors to Edge Servers. Data sources protect
their contents through Attribute-based Encryption and deliver them to Edge
Servers. In turn, Edge Servers implement Attribute-based Searchable
Encryption functionalities to properly disseminate received contents
towards Multi-Access Edge nodes hosting the applications that generated
valid Trapdoors. The performance of the conceived approach has been
evaluated through computer simulations. Obtained results highlight the
benefits achieved against baseline (i.e., cloud-based) solutions.},
