Abstract
An encryption circuit includes an iterative block cipher circuit. The iterative block cipher circuit has a counter input for a row index, a key input for receiving a secret key, and an output for providing an encrypted counter value in response to performing a block cipher process using the row index as a counter the secret key. The encryption circuit uses the iterative block cipher circuit during a row operation to a memory.
