Riassunto
The Internet of Things (IoT ) allows to automate a great number of tasks at
home, in the cities or in industry. IoT Devices are often constrained in term
of resources (computing power and memory) and energy, and they work in
constrained networks (limited message size and low bandwidth) these imply
security challenges.
Attribute-Based Encryption (ABE ) is a new type of public-key encryption
that ensures a fine-grained access control mechanism to encrypted data based
on flexible access policies. Unfortunately, it is very difficult to implement the
existing ABE schemes in the resources-constraint IoT, because they are all
on expensive elliptic curve operations.
The aim of this study is to asses the feasibility of Attribute-Based en-
cryption techniques on constrained devices. We first provide an overview
of the available security architecture, then we provide a case study with a
proposed security architecture and highlight how ABE encryption techniques
are a better fit to constrained environments where a high number of users is
present and a fine granularity of permissions is required. The final perfor-
mance evaluation shows that ABE can be adopted in constrained devices to
ensure a fine-grained control on data access with a cost that increases with
the number of attributes.
