AES-ECC and Blockchain in Optimizing the Security of Communication-Rich IoT

The communication-rich Internet of Things is a great opportunity for banks to modernize. The majority of IoT systems are composed of embedded software and hardware that collect and exchange data allowing them to connect to each other and to the internet which poses security issues. However, ensuring security, consensus in sharing remains a challenge in rich IoT communication. Therefore, such a vision requires, among other things, authentication, data privacy, robustness against attacks, easy deployment and self-maintenance. In this paper we propose to use hybrid AES-ECC cryptography with lightweight blockchain consensus algorithms namely DPOSA to optimize security, throughput and latency in the IoT platform. The blockchain facilitates the storage, distribution and immutable sharing of data at different nodes. Then a cooperative scheme of the different IoT actors is proposed. Finally, a scheme for managing encryption and decryption keys is proposed. The integration of the designer in the data management of his IoT is crucial for their security. The results obtained show a positive impact on the increase of the throughput and the security level and the decrease of the latency.
