近年來由於網路攻擊手法不斷更新,使得網路安全遭受到更嚴厲的挑戰;雖然目前有各種防制方法被提出,但大部分只能達到被動式的防禦功能;要能夠嚇阻駭客發動網路攻擊的做法之一,就是設計一有效找出攻擊來源的方法(我們稱之為IP traceback),藉此找到發動攻擊的駭客,加以法律或道德的制裁,使他們在發動攻擊時會有所顧忌,而不會任意的發動攻擊。

然而,IP traceback目前最困難的地方就是駭客可以輕易地偽造封包的IP來源位址,使得無法就封包的IP來源位址判斷真正的攻擊來源;針對IP來源位址被假冒的問題,有一種解決方式就是當封包經過其邊界路由器(Egress Router)時,由該路由器對此封包作簽章,之後當攻擊行為發生時,就可藉由驗證這些攻擊封包的簽章資訊,找到發動攻擊的來源處。

本論文將利用橢圓曲線密碼系統(elliptic curve cryptosystems)的身份碼簽章(identity-based signatures)技術,在Linux平台上實作一以IP位址為驗證公鑰之封包簽章機制(IP-Based Packet Signature,簡稱IPBPS)。在路由器上執行簽章勢必降低封包轉送的效率,因此本論文將結合”網路型入侵偵測系統(Network-based Intrusion Detection System,簡稱NIDS)”,當NIDS偵查到可疑封包時,即發送命令要求邊界路由器對那些可疑封包執行簽章,而在受害者端NIDS可透過驗證封包上的簽章,找到攻擊封包的來源位址。
Since network attacking technique keep renewing quickly everyday, the network safely is now facing a serious challenge. Although there are many ideas and methods being suggested to protect the network security, however, most of these methods could only achieve the purpose of passive protection. In order to stop these attacks from their unacceptable behavior, a better method must be use. For example, one of the methods is to identifying the actual source of attack packet sent across the Internet, by using the technology call “IP traceback”. As a result, these attacks can be catch immediately. By using “IP traceback”, people will behave themselves because the law will give attacker proper judgments, and therefore, the chances of network attacking will be reduce.

However, the most difficulty of “IP traceback” is that attacker can create a fake source address. As a result, “IP traceback” is unable to detect the attacker’s proper location by packet’s source address. To solve fake source address problem, we use an egress router to assign a signature. When discovery attack behavior, people can to test and verify packet’s signature, and therefore, attacker’s original location will be found.

In this paper will use the identity-based signatures technique based on elliptic curve cryptosystems, make a packet signature mechanism which verify use the common IP address to perform in Linux system (IP-Based Packet Signature, abbreviated as IPBPS). Will carry out the signature on the router inevitably to reduce the efficiency, therefore this system will unify “Network-based Intrusion Detection System” (abbreviated as NIDS).

When NIDS is investigated to the suspicious package, namely send the order and require Egress router to carry out stamped signature to those pass packages. We can find the attacker’s original location through verifying the stamped signature on the package in the victim''s NIDS.
