Impact encryption algorithm used in three pass protocol for securing WiMAX link
Suherman Suherman · Journal of Physics Conference Series · 2021
Wireless network is popular for internet connection. WiMAX provides higher bitrates connection compared to the popular 802.11 network. Since wireless link is more security risk than the wired one, solutions for securing the wireless link are often proposed by many researchers. Since WiMAX link employs contention request for best effort service which lead to higher delay, security solution should not inject excessive link delay. This paper examines the use of three pass protocol (TPP) in transferring the encryption keys. One time pad protocol (OTP) is the basic key encryption within TPP. Since OTP is a simple XOR key, its protection is weak. This paper compares link delay produced by more advance encryption techniques when replacing OTP within TPP. Simulation shows that with the security increment, blowfish encryption produced the lowest link delay increment lower than 150 ms. While AES, 3DES and DES results excessive delay.
