The paper considers the implementation of AES-256 Rijndael encryption in the Edge AI robotic system to protect the integrity of telemetry and sensor data. The initial problem is the conflict between massive data acquisition, real-time execution and the limited resources of a low-cost robotics platform. The proposed approach uses a dual-core organization based on the freeRTOS division of labor, with Core 0 performing acquisition and cryptographic processing, while Core 1 performs kinetic control, odometry, and fail-safe mechanisms. AES is standardized as a block symmetric algorithm with variants AES-128, AES-192, and AES-256, with AES-256 using a 256-bit key and a 128-bit data block (National Institute of Standards and Technology [NIST], 2023).
