论文摘要
我们使用Kyber-512（一种基于晶格的钥匙封装机制和NIST PQC标准化过程中的第三轮决赛投篮命中率）在低地球轨道中使用纳米卫星Spooqy-1在低地球轨道中使用纳米卫星Spooqy-1证明了量子后的钥匙交换，在NIST PQC标准化过程中，我们证明了一种量子后的键交换，在NIST PQC标准化过程中使用纳米卫星Spooqy-1。我们的固件解决方案在基于ATMEL AVR32 RISC微控制器的机上计算机上运行，该计算机是纳米卫星广泛使用的平台。我们使用Cubesat Space协议（CSP）使用436.2 MHz UHF链路上传了新固件，并在瑞士的多次通过中执行了密钥交换的步骤。本实验中生成的共享秘密密钥可能可能用于使用AES-256加密RF链接。该实现证明了量子安全验证的键交换和加密系统在交换受约束的纳米卫星上的可行性。
We demonstrate a post-quantum key-exchange with the nanosatellite SpooQy-1 in low Earth orbit using Kyber-512, a lattice-based key-encapsulation mechanism and a round three finalist in the NIST PQC standardization process. Our firmware solution runs on an on-board computer that is based on the Atmel AVR32 RISC microcontroller, a widely used platform for nanosatellites. We uploaded the new firmware with a 436.2 MHz UHF link using the CubeSat Space Protocol (CSP) and performed the steps of the key exchange in several passes over Switzerland. The shared secret key generated in this experiment could potentially be used to encrypt RF links with AES-256. This implementation demonstrates the feasibility of a quantum-safe authenticated key-exchange and encryption system on SWaP constrained nanosatellites.
