SECURE CLOUD DATA AND PRIVACY BASED REPLICATION SYSTEM IN DUAL CLOUD

Abstract

The growing use of web-based programs for data retrieval and control calls for strong security features, particularly when sensitive data is being shared. This work introduces a system for secure data transmission between a web page and an Arduino microcontroller through Advanced Encryption Standard (AES) encryption and decryption. The system encrypts data at the client-side webpage through JavaScript and sends the ciphertext to the Arduino for decryption through an AES library. This method allows for secure communication in Internet of Things (IoT) applications or other situations where low-cost, secure data transfer is needed. We outline the implementation of AES on both the webpage and the Arduino, including key management techniques. We also include performance metrics and security considerations. The objective is to prove the viability of employing Arduino as a low-cost, yet secure, data transmission device between a webpage and a physical world interface for facilitating improved data security and privacy. Experimental results indicate that the system can encrypt and decrypt data within acceptable durations for some IoT applications.
