Figure 7-104 f8 Feedback ModeFigure 7-104 illustrates the f8 Feedback Mode of operation for both encryption and decryption. The input to the crypto core is the result of the XOR operation of the previous crypto core output, a constant IV and a block counter. The output of the crypto core is XOR-ed with the input to create the result. In this mode, encryption and decryption use the same operations.
