Drill jumbo state monitoring data encryption method based on improved AES algorithm

The drill jumbo state monitoring data encryption method based on the improved AES algorithm comprises the following steps: determining the key length of the AES algorithm; an encryption round function and a decryption round function of the AES algorithm are optimized; the optimization method comprises the following steps: adjusting the execution sequence of row shift operation and byte substitution operation in an encryption round function of the AES algorithm, and adjusting the execution sequence of inverse row shift operation and inverse byte substitution operation in a decryption round function of the AES algorithm, adjusting a column confusion matrix in an encryption round function of the AES algorithm and an inverse column confusion matrix in a decryption round function of the AES algorithm to be symmetric matrixes; xtime multiplication in the optimized encryption round function and decryption round function is replaced with table look-up operation, and an improved AES algorithm is obtained; and acquirin
