With its rapidly growing, the security of wireless network is becoming more and more important. As a traditional issue among lots of subjects about wireless network security, key exchanging never lacks attention. By the advancing of microelectronics, the authors propose an improved version of Aydos's protocol, which uses the restraint of RTT. The new protocol can resist two types of MITM attack that presented by the researchers. It can even resist the strengthened MITM attack in which the attacker has in finite computing resource. They then analyze the new protocol both theoretical and experimental.
