However, so far, no Internet-level IP trace back system has ever been deployed because of deployment difficulties. In this paper, we present a flow-based trace.

RIHT, however, requires 32 bits for marking and consequently cannot make 0 false positives. When the degrees are over 90, UI i has to be logged in the table and therefore the marking field allows a higher index value.

But our scheme requires an interface number to be logged if it exceeds the threshold value. A novel traceback algorithm for Netwodk attack with marking scheme for online system. Relation between Router Degree and Table Size As shown in Figure 4when a router’s degrees are below 90, the table’s maximum size decreases quickly with the increase of router degrees.

Then the router writes its ID and the packet’s upstream routes into the mark, so that the downstream routers can use the mark to trace the origin of the attack.

Yang propose RIHT [ 24 ] to encode all the upstream routers’ interface networ as their log table’s indexes. Table 2 Example of any log table HT k. Besides, these three methods use packet marks to compute their log table’s index am and then use the value to compute a new mark.

LauferPedro B. Therefore, when adversaries send attack packets with a forged path in the marking field trying to confuse our tracking, we can still locate their origin correctly. Performance Analysis In this section, we will introduce our simulation environment and how we determine log table size and the threshold.


To prevent the problem of insufficient table entries, we create a new table when the table is full. As depicted in the figure, compared with HAHIT our scheme requires fewer logging times and our logging times do not increase with the number of packets. But a large degree D R i makes a large logged mark, which can cause high logging frequency and increase the storage requirements for its downstream routers.

The router can only accommodate log tables tracebsck size ranges from 4 to 7. In Ror 2we use dotted lines to indicate the path reconstruction of packet P 1. Because our scheme, HAHIT, and RIHT have low storage requirements, routers can keep the path info for a long time and therefore do not need to refresh their log tables under flood attacks, hence 0 false negatives.

When the threshold is set as 10, the table has 8 entries ss and the router has the fewest logging times. Since adversaries may spoof their source IPs in the attacks, traceback schemes have been proposed to identify the attack source. Network topology Autonomous robot Software deployment Internet System deployment. As shown in Table 1we use the bit ID field as our marking field in our traceback scheme.

As these packets are usually in a huge amount, these marking schemes are categorized as probabilistic packet marking PPM [ 3 — 9 ] and deterministic packet marking DPM [ 10 — 14 ]. The other type encodes a packet’s route overlau a mark and stores it in the packet’s header.

In the following discussion, we use D R i to indicate the degree of router R ithat is, the number of routers adjacent leve, R i. Some even have false positives because they use an IP header’s fragment offset for marking. MoreiraRafael P. Because the required storage for our routers’ log tables is bounded by route numbers, it does not grow with the number of passing packets.


Security assessment of the internet protocol version 4. In this section, we will introduce our simulation environment and how we determine log table size and the threshold. Ab use the free fields of each packet’s IP header to mark the packet’s route and the routers along the route.

Storage-Efficient Bit Hybrid IP Traceback with Single Packet

For example, R 9 serves as a border router when it receives packets from Host. When a router receives a ndtwork P j and needs to log its mark, the router checks its degree D R i to decide whether or not to log the interface number UI i ; compare lines 29—33 in Algorithm 1. The storage requirements of logging are bounded by the number of upstream routes, and no duplicate route is logged. In order to balance the collision times and each table’s usage rate, Yang sets his load factor as 0.

The marks include the routers’ interface numbers and are passed to the next router with the packets. Normally the source and destination IP addresses are stored in a packet’s IP header to indicate its source and destination. After packet P 2 passes through the routers R 1 and R 2it enters R 3 and needs to be logged. It is because our log tables allow more entries on the routers traveback degrees are under the threshold value 10, and because we do not use fixed-size tables.
