Defend Dos Attack with Geometric Hashing Function and Software Puzzle
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 5
Abstract
DOS attack can be exhaust the target server’s resources have become major threat to today’s internet. Even though client problem represent a promising way to defend against certain classes of DOS attack, several questions stand in the way of their use in practice. Existing software puzzle system issues their puzzle algorithm already. The attackers can easily solving the puzzle using puzzle solving software. We proposed a new client puzzle software algorithm that can choose puzzle algorithm randomly during the request form the client. The attacker cannot show progress since server chooses the puzzle algorithm randomly. We implement an efficient password authentication scheme based on a geometric hashing function in order to improve the confirmation. A single message prepared by the client and sent to the server, and a confirmation performs by the server. It efficiently defends beside DOS, verifier-stolen attack, replay attack, password guessing attack, min-in-the-middle attack.
