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.

A more efficient hybrid approach for single-packet IP traceback. A large table leads to large index values and large marks, which will cause high logging frequency in the downstream routers. CastelucioRonaldo M. It is because our log overlqy allow more entries on the routers whose degrees are under the threshold value 10, and because we do not use fixed-size tables. A marking scheme using huffman codes for IP traceback.

This security issue has come to our attention and we find it urgent to propose an efficient traceback scheme tracking the real source of impersonation attacks.

Skip to search form Skip to main content. Because the required storage for our routers’ log tables is bounded by route numbers, it does not grow oevel the number of passing packets. In our protocol, any router R i and its network topology has to follow the following assumptions:.

An AS-level overlay network for IP traceback

To simulate the Internet topology, we use the skitter project topology distributed by CAIDA [ 29 ] as our sample data set of the Internet. They use the free fields of elvel packet’s IP header to mark the packet’s route and the routers along the route. When a packet enters a network from its host, every router that complies with our protocol has to mark its own route info on the passing packets and store the mark in each packet’s marking field.


In Figure 2we use dotted lines to indicate ldvel path reconstruction of packet P 1. In the first type, when a border router receives a packet from its local network, it sets the packet’s marking field as zero and forwards the packet to the next core router.

Storage-Efficient 16-Bit Hybrid IP Traceback with Single Packet

IP traceback with deterministic packet marking. Conflict of Interests The author declares that there is no conflict of interests regarding the publication of this paper. It needs to do an exhaustive search during path reconstruction, so as to find the corresponding upstream interface number of the attack packet. But in a software exploit attack, a villain needs to find the host’s vulnerabilities and then uses only a few packets to launch attacks, for example, Teardrop attacks and LAND attacks [ 2 ].

Hybrid single-packet IP traceback with low storage and high accuracy. A router will compare its degrees with a threshold to lwvel a coding scheme to calculate the mark. The storage requirements of logging are bounded by the number of upstream routes, and no duplicate route is logged.

When UI i ‘s maximum number increases with the degree, the index value has to decrease. However, such a marking and logging method may require more log tables on a router.

Storage-Efficient Bit Hybrid IP Traceback with Single Packet

In order to balance the collision times and each table’s usage rate, Yang sets his load factor as 0. And a conclusion is drawn in Section 4. However, in Lu et al. The routers do not need to search their log tables during path reconstruction. Marking and Logging In our marking scheme, we mark a router’ interface numbers and store the mark in a packet’s IP header. 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.

In doing so, we can effectively lower the logging frequency. If the log tables are refreshed, the traceback scheme is unable to reconstruct the attack route. 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.


When a router receives the packet, it uses the packet’s destination IP as an index to choose a log table to log this mark.

Next the router sends the new mark to the downstream router. In the simulation, we send the packets to a randomly chosen path and count the logging times on the largest router in CAIDA’s dataset, whose degree is Also, we propose a logging scheme to further reduce the storage requirements for logging. Some even have false positives because they use an IP header’s fragment offset for marking. 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.

Accommodating fragmentation in deterministic packet marking for IP traceback.

Security assessment of the internet protocol version 4. The main contributions of our scheme are listed below and we aim to satisfy the first three so as to achieve the last two: If there are any routers unable to comply with this scheme, they can establish a tunnel to communicate with each other. References Publications referenced by this paper. Besides, because a router that supports IPsec may need to add Neteork header to each packet, it can increase a packet’s length and the chance of fragmentation.

But an IP header has only limited space, so we combine logging with marking to log marks on the routers. Fod, we can decrease the storage requirements by reducing the logging frequency. A novel traceback algorithm for DDoS attack with marking scheme for online system.

In quadratic probing, the load factor suggests the usage rate of each log table. When P 1 passes through R 1 en route for R 2its mark is larger than
