Abstract :
In order to use the Internet of Things as a secure infrastructure, there are various challenges and problems, of which security is one of the most important. Establishing security in such networks has many complications due to the limitation of various resources, including processing resources and low energy, and there is a need to establish a kind of compromise between security and available resources. These conditions have caused security to become an important challenge in these networks, and various methods have been presented to improve and optimize this challenge. Accordingly, in this article, a lightweight encryption solution based on symmetric and asymmetric encryption is presented to ensure data security on the Internet of Things. In the proposed method, first, the main data is encrypted by the symmetric Bluefish algorithm, and then its key is secured with the help of the elliptic curve encryption algorithm, so that as a result, data security can be ensured in a short time and with high security in infrastructures based on the Internet of Things provided. In the end, the proposed solution has been evaluated through the Eclipse simulator and by testing on the data volume of 20 to 1000 kilobytes. The simulation results show that the proposed method performs more optimally compared to other encryption algorithms in terms of evaluation criteria such as execution time and encryption and decryption throughput. These results indicate that the proposed solution, while establishing security, has had the least negative impact on the processing resources of IoT nodes.
