Abstract
The disclosure provides a Galois hash authentication-based circuit. An additional authentication data calculation circuit receives the first data block in the data stream and performs calculation according to the first data block, and shifts the calculation result to the left to generate a first output. A ciphertext calculation circuit includes k first calculation units, used to receive in parallel the second data blocks in the data stream in each round of calculation of the ciphertext calculation circuit, and perform parallel calculation on each data block received to generate a second output. The bubble processing circuit receives the first quantity of the third data blocks after the last round of calculation of the ciphertext calculation circuit and performs calculation to generate a third output. A message authentication code is calculated according to the first output, the second output, and the third output.
