Marking Certification of Adaptive Probability Packet Based on Hash Function

Abstract

Denial of Service Attack is a very important security event in the current network security .Address the problem of DDoS Network Attacks ,researchers have proposed a variety of tracking programs against Denial of Service Attack .Such as IP tracking program, packet marking ,logging ,connection test ,ICMP tracking ,covering networks ,and so on .The marked storage space has been expended by the use of authentication machnism of adaptive probability packet .Increasing marks could store the hash value of the IP addresses of the head node .With the selection of the mentioned two methods above ,the quantity of needed packet while reconstructing the path has been decreased .And ultimately ,the propose of decreasing the rate of false positives and the computational complexity ,as well as improving the convergence and security have been reached.
