Kiruthika}, country = {}, institution = {}, abstract = {In this paper, we explore a new scheme for filtering spoofed packets (DDOS attack) which is a combination of path fingerprint and client puzzle concepts. In this each IP packet has a unique fingerprint is embedded that represents, the route a packet has traversed. The server maintains a mapping table which contains the client IP address and its corresponding fingerprint. In ingress router, client puzzle is placed. For each request, the puzzle issuer provides a puzzle which the source has to solve. Our design has the following advantages over prior approaches, 1) Reduce the network traffic, as we place a client puzzle at the ingress router. 2) Mapping table at the server is lightweight and moderate. }, journal = {International Journal of Computer and Information Engineering}, volume = {2}, number = {9}, year = {2008}, pages = {3037 - 3042}, ee = {https://publications.waset.org/pdf/1872}, url = {https://publications.waset.org/vol/21}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 21, 2008}, }
