Improved Rsa Algorithm for Data Security against DDoS Attack in a Cloud-based Intrusion Detection System

Abstract

Today, more and more industries are using cloud computing for some integration operations, but ensuring the security of user data and system resources remains a challenge. This article proposes a method to identify and mitigate unwanted packets and traffic, especially duplicate packets, in cloud computing environments. The method includes creating an Intrusion Search and Detection (IF-AD) system to securely maintain user information and allocate secondary memory. To detect unwanted traffic, this method compares the size of the downloaded file  with the original file, identifying any differences as potential DDoS.  RSA encryption mechanism is used for subsequent file transfers for added security. The proposed approach aims to enhance the security posture of cloud-based systems by detecting and preventing unauthorized access and file modification.
