一种基于区块链的高校联盟链DDoS防御改进方法

A Method for Improving DDoS Defense of University Consortium Chain Based on Blockchain

5G时代的到来,网络流量增加,攻击者利用这些设备发动分布式拒绝服务攻击(DDoS)的威胁.目前基于区块链的DDoS防御方法是在公有链以太坊上部署智能合约,但需支付以太币(ETH)来调用智能合约,费用高,不适合高校的DDoS防御部署.本文提出基于联盟链构建DDoS防御,在联盟链上部署智能合约,不需支付额外费用就能调用智能合约,通过实验验证了本方法的安全性、可用性和可扩展性,适用于高校的DDoS防御部署.

With the advent of the 5G era,network traffic increases,and attackers use these devices to launch the threat of distributed denial of service(DDoS)attacks.The current blockchain-based DDoS defense method is to deploy smart contracts on the public chain Ethereum,but it is necessary to pay ether(ETH)to call the smart contracts,which is expensive and is not suitable for DDoS defense deployment in colleges and universities.This paper proposes to build DDoS defense based on the alliance chain,deploy smart contracts on the alliance chain,and call the smart contract without paying additional fees.The security,usability and scalability of this method are verified by experiments,and it is suitable for DDoS defense in colleges and universities deploy.
