摘要: 基于ECC的前向安全数字签名方案,签名中使用了不变量 ,尽管签名私钥是前向安全性的,但实际上签名不具有前向安全性。该文提出了关联因子的概念,利用关联因子构造了一种新的基于ECC的前向安全数字签名方案,该方案不仅具有前向安全性,还具有较强的抗伪造性,有一定的理论和实用价值。

Abstract: This paper presents an alerts association analysis technology based on intrusion intention in order to overcome the problems exited in today’s alerts association analysis technologies. This method not only inherits the merits of the alerts association analysis technology based on intrusion strategy such as foreseeable, but also improves the adaptability of the intrusion strategy model. Furthermore, it gives the “skipping step” analysis mechanism and its improvement on the comprehension ability of the intrusion detection system.
Key words:
Intrusion detection,
Alerts information association analysis,
Intrusion strategy model
