An Improved and Secure Handoff Authentication Mechanism for Cellular Network

Abstract

The springing of new mobile application and demand of security has started new era of development in cellular networks. In this paper, a new technique to ensure security and improved efficiency in handoff for cellular telecommunication networks is presented a new technique using an RSA encryption. To enhance the conventional handoff process, a technique called Enhanced Handoff Mechanism (EHM) is introduced where the vital performance criteria incorporate latency, signal strength, throughput, packet loss, energy consumption, and jitter. With the incorporation of RSA encryption, the EHM also guarantees the security of the messages that are used to perform handoff, thereby  reducing the possibility of exploitation of certain security weaknesses.Results are evaluated and compared the simulation results of the traditional handoff mechanism against the proposed EHM using a set of hypothetical scenarios and findings reveal substantial improvements across key performance metrics: The EHM elongated the handoff latency. The improved handoff completion ratio by 10 percent, increased the signal strength by 10 dBm, ensured at least 25 Mbps of throughput, and cut down the rate of packet loss by 4 percent, energy by 30 Joules, and jitter by 30 ms.
Python’s cryptography library was used to ensure that all mechanisms of encryption and decryption were indeed working and the message handoff was accomplished successfully with the help of RSA keys. Results shown by EHM has a marked improvement compared to the traditional method of sending messages. The time series analysis further reinforces the trend analysis supporting the arguments that made on how the EHM performs well under different network scenarios. This research offers an improved and secure  approach towards enhancement of handoff mechanisms within the cellular networks using RSA encryption. The Enhanced Handoff Mechanism presents a best secured solution in lieu of performance metrics of existing cellular network handoff and leads on the way to more secured communication protocols.
