Novel Approach Implementation of AES Algorithm Based on Radiation-Tolerant FPGA for Secure Mission in Satellite Remote Sensing: LST-SW Case

Security applications in remote sensing missions have grown in the recent decade since the confidentiality of data carried from satellite to ground station can be hacked, and the space environment can damage satellite hardware. This study provides a unique architecture for secure Land Surface Temperature via radiation FPGA based on the AES algorithm. The T-Box method was used for the implementation of the AES algorithm. The testing results demonstrate that the suggested implementation achieved a throughput of 524.26 Mbps using Xilinx Virtex-4QV FPGA, at a maximum clock frequency of 208.453. Furthermore, the proposed solution occupies 8% of the slice in terms of area consumption. Moroever, an evaluation of the suggested method for prior implementation reveals that the presented approach has the best trade-off between area utilization, frequency, and throughput. Therefore, The suggested approach offers excellent performance, making it appropriate for future satellite remote sensing missions that utilize radiation-tolerant LST-SW computations.
