Zusammenfassung:	The invention relates to a register protection method, device and system, and the method comprises the steps: firstly, after a CRC control logic outputs a selection signal, a selector selects a corresponding register value from a protected multi-path register according to the selection signal, transmits the selected register value to a CRC calculation module, and is connected with the multi-path register in parallel; after a CRC calculation module completes CRC calculation of register values of all registers in the current round, a corresponding CRC calculation result is obtained; and finally, obtaining the value of the CRC calculation result comparison register, if the value of the CRC calculation result comparison register is valid, comparing whether the value of the CRC calculation result comparison register is consistent with the value of the CRC calculation result, and if the value of the CRC calculation result comparison register is not consistent with the value of the CRC calculation result, sending ou
