摘要

The traditional encryption schemes were designed for text and/or images that needed to be exchanged among various machines, which are assumed to be coherent. The allotment of resources to assure minimum user requirements and data quality is a challenging task. The reality and need of today's communication is experiencing huge communication overheads due to text, images and multimedia files generated by mobile users. It does not only create security threats, but also challenges the allotted bandwidth and signal quality. To address the aforementioned issues a bandwidth-efficient lightweight authentication scheme for 5G HetNets has been proposed. The performance analysis of security level and computational complexity with different key and data categories has also been done to ensure the data security and reduces the overheads. Three different cases have been analyzed based on key type and their lengths to circumvent the overheads for the combination of each data length with security level. The key transportation problem has been solved by generating the keys from the data pool. Hybrid keys are generated at both transmitter and receiver from the data pool based on the algorithm; therefore, these keys need not be transmitted. The simulation results confirm the performance and the efficiency of the proposed algorithm in terms of the (a) image quality that are in the range 36 and 43 dB for different formats, (b) minimum encryption time ranges from 92.54 to 131.76 ns, and (c) less heat dissipation ranges 2547–4024 µW and flexible to select different data and key length.
