Quick system scenario: You have packet [A].
It gets encrypted using an AES algo in a particular mode and we are left with [zA]. More data [B] is added to that encrypted packet. Now I have [zA]+[B] in one packet and I re-encrypt it with the same algo/key/mode. Have I just compromised the security somehow? I wasn't aware of anything but something about this double encryption made something ring in my mind so I wanted to double check...
