Query: VDAS: Verifiable Data Aggregation Scheme for Internet of Things   Along with the miniaturization of various types of sensors, a mass of
intelligent terminals are gaining stronger sensing capability, which raises a
deeper perception and better prospect of Internet of Things (IoT). With big
sensing data, IoT provides lots of convenient services for the monitoring and
management of smart cities and people's daily lives. However, there are still
many security challenges influencing the further development of IoT, one of
which is how to quickly verify the big data obtained from IoT terminals.
Aggregate signature is an efficient approach to perform big data
authentication. It can effectively reduce the computation and communication
overheads. In this paper, utilizing these features, we construct a verifiable
data aggregation scheme for Internet of Things, named VDAS, based on an
improved certificateless aggregate signature algorithm. In VDAS, the length of
the aggregated authentication message is independent of the number of IoT
terminals. Then, we prove that VDAS is existentially unforgeable under adaptive
chosen message attacks assuming that the computational Diffie-Hellman problem
is hard. Additionally, the proposed VDAS achieves a better trade-off on the
computation overheads between the resource-constrained IoT terminals and the
data center.
