Therefore,it is important to control both impact time and impact angle for flight vehicle’s homing problem simultaneously.

The virtual-leader is introduced,which would fly straightly to the target from the designated impact angle at the designated impact time.

The most widely accepted defense against timing attacks is to perform RSA blinding,which has a performance penalty.

This paper describes the basic concept, principles, and history of timing attack, the readers can thus have a basic understanding of this area.

The most widely accepted defense against timing attacks is to perform RSA blinding,which has a performance penalty.

Researching on timing attack at the accelerating implementation algorithm of RSA

This thesis firstly introduces the basic theory of timing attack and the discription of the related algorithms, and then taking the modular exponentiations for example, emulates the attack process, finally analysises the advantages, several prob- lems waiting for further study and the trend of timing attack.

A timing attack to rerouting-based anonymous communication was presented according to these problems.

This paper,proposes a general anonymous communication model based on rerouting,and a timing attack model also has been presented according to this model.

The current status of development in firewall technology and the active-defense thought in face of the zero-day attack has been analyzed and studied,as well as the active-defense in firewall system.

This paper analyzes and researches the evolution of firewall technology and active prevention against “Zero-day Attack”, and discusses the implement mechanism of Active Prevention’s Mechanism in Firewall System.
