I would like to know about a
mechanism of using AES-128 block cipher (in any secure mode of operation) for frame (Ethernet frame at data link layer) encryption. Please note that the size of frame will not be multiples of block size and frame size will not be constant for all frames. Also, for synchronisation purpose we prefer not to carry-forward the current frame bits to next frame.
