Abstract
The present invention provides a traceback method including: receiving data including router information according to a path of an attacker; filtering the data to hash the data, and storing the resultant hashed information; determining whether the data is normally received on the basis of the hashed information; and predicting a path loss on the basis of the determination result. Therefore, it is possible to perform an accurate IP traceback using a probabilistic packing marking method and a hash-based traceback method.
Claims19
A traceback method comprising:
- receiving data including router information according to a path of an attacker;
- filtering the data to hash the data, and storing resultant hashed information;
- determining whether the data is normally received on the basis of the hashed information;
- and
- predicting a path loss on the basis of the determination result.
A signal receiving apparatus comprising:
- a receiver that receives data including router information according to a path of an attacker;
- a filter that groups the data and classifies acknowledgement information of the groups;
- a storage unit that stores the acknowledgement information;
- and
- a determining unit that determines whether the data is normally received on the basis of the acknowledgement information and predicts the path of the attacker.
