The Secure Data Transmission Method of a Cellular Communication Network Based on the Asymmetric Encryption Algorithm

Abstract

In order to improve the cellular network communication security and achieve a high quality data transmission, this paper proposes a method of secure data transmission. The proposed method is based on asymmetric encryption algorithm. This paper analyzes the composition structure of cellular network to establish the network architecture model and master the communication characteristics. The public key system is constructed using the certification center, service provider and users, and the asymmetric encryption process. The public key system is analyzed to obtain the encrypted cipher-text by optimizing the integer grouping method. Overall, results show that the proposed research achieves a higher throughput, and reduces bit error rate compared to the state-of-the-art methods. Results and findings suggest that the proposed transmission method can improve reduce the probability of data theft, and reduces transmission energy consumption to ensure data transmission security from multiple aspects.
