An Approach to Detect and Prevent Distributed Denial of Service Attacks Using Blockchain Technology in Cloud Environment

摘要

Cloud is a novel platform providing on-demand services, web applications, network, server and storage. In spite of having problems associated with security and privacy, the cloud brings out a wide range of benefits. The distributed denial of service (DDoS) attack remains a security challenge in achieving a secure and guaranteed service and resources in cloud computing. The users have to face a problem regarding resources while having a DDoS attack. Therefore, it results in significant downtime and financial losses. Blockchain technology provides an enhanced security and privacy in many domains, like IoT, cloud, data mining and networking. It also provides a decentralized security framework, therefore, allowing sharing of attack information in a completely distributed and automated manner. Blockchain adds an additional layer of security and ensures that bad actors don't take control of systems for their own ends in cloud environment. The system proposed here offers a solution to secure data on cloud environment built on blockchain technology that detects and prevents DDoS attack.
