DDoS (Distributed Denial of Service) attack utilizes sufficient puppet computers to create amount of data packets. It can use DoS attack to assault one or more targets, exhaust the resources of injured end then to bereave the regular services. This article is to elaborate the formative principle of DDoS, analyze the security precautions and bring the defense frame.
Petri Nets is a powerful mathematical modeling tool for system description and analysis, with which we can describe the relationship among entities efficiently. The present thesis puts forward the basic modeling of the distributed computer network - DNMPN based on Petri Nets. DNMPN implements the basic function of distributed computer network, and DNMPNT modifies DNMPN's repetitive forward problem...
With the increasing development of information technology, the computer crime problem is getting even serious. However traditional computer forensic that employs the static investigation after security events has inherent limitations. The authenticity, effectiveness and timeliness of the evidence are difficult to meet real needs. In order to solve the existing problems which static forensics technology...
A scheme is presented for orienting application, which is based on micro-magnetic sensor and accelerometer, and the scheme can solve the orienting problems well. We have an optimized arrangement of the two sensors' positions, whi ch provides premise for establishing reference coordinate. An algorithm for completely oriented sensing is applied. In the algorithm, we take a concept of relative coordinate,...
