AB  - The UMTS system and architecture are designed to accommodate Internet-like mobile services and specific services like mobile commerce to mobile users. They bring attacks from Internet and mobile users as well. Denial-of-Service (DoS) attacks aim to frustrate a legitimate user’s access to mobile services or bring down servers by depleting system resources. Many approaches are proposed to thwart these attacks. This study focuses on man in the middle attack, authentication based condition and integrity protocol with a quassi puzzle to ensure the security. To resolve the re-direction attack SGSN is used. Here it uses Payload Encryption Key (PLK) to handle the man-in-the-middle attack. Next for bandwidth reduction a ticket-based authentication scheme is used. In addition to these, for ensuring the integrity EMSUCU protocol is used. A quasi puzzle is given at the last for the defensive mechanism client puzzles based on quasi partial collisions is used. Here the DDoS attack is detected in a three way detection phase. Signaling and travesing through a number of network nodes enhances the detection in earlier manner and clear idea of attack detection. Quasi puzzle is quite easy and secure algorithm for avoiding the DDoS attack as soon as it is detect.
