INTRODUCTION: IoT devices are small, have limited battery and computing capabilities, and cannot tolerate complex encryption. So there is a need for a lightweight cryptographic scheme that can perform well in resource constraint environments.OBJECTIVES: Many encryption algorithms struggle to balance security and complexity. Increasing the level of protection necessitates increasing complexity, which leads to higher encryption and decryption times. The goal of this article is to offer a novel encryption method, the Modified Rijndael Algorithm, which balances security and complexity. METHODS: The classic Rijndael encryption technique has been modified to make it lighter and more secure, suitable for resource-constrained IoT devices. These modifications include adding the novel pre-processing step Crossover based on the two-point crossover operation of genetic algorithms, removing the Sub Byte step, changing the shift column phase, and decreasing the rounds.RESULTS: The proposed scheme provides speed and high security, increasing efficiency and randomness while reducing encryption and decryption times by 21.06% and CPU consumption by 13.2% compared to the traditional method.CONCLUSION: The proposed algorithm reduces encryption time and maintains the complexity needed to protect the data. It is lighter and more secure, making it suitable for IoT devices with limited resources.
