ECC-based Secure Communication Platform for Unmanned Systems

With the rapid development of information technology, information security has become particularly important in the field of communication. To address the limited resources and low computing power of traditional edge platforms, in this paper, an Elliptic Curve Cryptography-based secure communication platform for unmanned systems was developed. Firstly, the platform adopts the Elliptic Curve Cryptography algorithm as the underlying computing support for secure communication. Besides, in its hardware implementation, multi-level pipeline and three-level parallel computing were adopted to achieve high-speed operation of its critical computing. Secondly, in order to increase the flexibility and programmability of the system, for computing on the secure communication protocol layer, the Linux operating system deployed on ZYNQ-7000 SoC is used to achieve programmability and hardware calls to the secure communication protocol. The results show that the ZYNQ-based secure communication platform can complete a dedicated protocol key negotiation in 12.6ms, which is significantly faster than the 28.8ms computing speed based on the same CPU (dual core ARM Cortex-A9) software implementation. It can improve the speed of secure communication while ensuring the flexibility and programmability of unmanned system applications.
