The invention relates to the technical field of data backup, and discloses a data backup method, which is applied to a controller, the controller supports CAN communication, and the method comprises the following steps: obtaining original data in a controller memory; converting the original data into a to-be-backed-up data frame, wherein the to-be-backed-up data frame is adapted to a CAN communication protocol; and when the memory occupancy rate of the controller is lower than a preset occupancy rate threshold value, sending the data frame to be backed up to the intermediate network equipment through a multi-packet sending mechanism of the CAN bus. Through the technical scheme of the invention, the problem of low efficiency of data backup of the engineering machinery in related technologies is solved, and the data backup efficiency of the engineering machinery is improved.

This invention relates to the field of digital information transmission security and discloses a design method for an SM2 hardware accelerator resistant to side-channel attacks in an RTOS. The method includes: constructing an absolute time window strictly aligned with the communication time slot period based on a bus synchronization clock; monitoring the SM2 operation progress within the window and automatically triggering an isochronous flow control unit upon completion of the actual instruction; this unit drives the operation core to perform twin pseudo-instruction filling on irrelevant data, isomorphic to the actual instruction, until the window terminates and the result is output. This invention physically shapes non-constant-time cryptographic operations into carrier signals with fixed timing and continuous equal-amplitude power envelopes, eliminating feature leakage in differential power analysis and ensuring that the hardware accelerator presents a zero-jitter, time-rigid node to the RTOS, thus meeting the stringent requirements of deterministic transmission in industrial time-sensitive networks.
