BlockLoc: Secure Localization in the Internet-of-Things using Blockchain
Ref: CISTER-TR-190408 Publication Date: 24 to 28, Jun, 2019Abstract:
Several IoT applications are tightly dependent on
the locations of the devices. However, localization algorithms can
be easily compromised by injecting false locations. In this paper,
we propose a Blockchain-based secure localization algorithm
for the Internet of Things (IoT). The algorithm uses a public
ledger (Blockchain) that contains nodes position and the list
of their neighbor nodes. This ledger is shared among the IoT
devices. Once an IoT device is localized its new position and
the list of neighbor nodes are added to the Blockchain. This
shared localization data will be used later by other IoT devices
for their localization process. To avoid the attack where a
malicious node sends a fake position, the correctness of the
claimed position are verified before adding it to the Blockchain.
Moreover, data exchanged between nodes (IoT devices) are signed
to guarantee their authenticity and integrity. The integration of
these security mechanisms into the localization process permits
to exclude false data and therefore reduces the localization error.
The simulation results show that adding the proposed security
mechanism improves the localization accuracy of the algorithm
when running in the presence of malicious nodes.
