Security of IoT Device and its Data Transmission on AWS Cloud by Using Hybrid Cryptosystem of ECC and AES

The expanding prevalence of the Internet of Things (IoT)and its devices presents significant security challenges mostly a lack of multi-factor authentication, light encryption, etc. This study uses Elliptical Curve Cryptography (ECC) and Advanced Encryption Standards (AES) to create a hybrid method with multiple security features for Raspberry Pi and data transmission on the cloud named Hybrid Cryptosystem ECC +AES. Data gathered and transferred to the cloud offers a faster and safer encryption mechanism on Raspberry Pi. This technique provides a notable gain in encryption performance over other previous algorithms by utilizing the speed of AES and the secure key exchange of ECC. The author developed a web application and implemented the algorithm for generating sample data, encryption, decryption processes, and uploading files to an Amazon Web Services (AWS) S3 bucket using Python programming which will benefit other IoT devices with limited memory and computational power.
