Abstract
A method for communicating in a network is presented. The method includes encapsulating content from a plurality of high level data units from a high level layer to generate a stream; dividing the stream into a plurality of segments; individually encrypting at least some of the segments, wherein an encrypted segment includes a plurality of encrypted blocks, and at least some of the encrypted blocks are encrypted based on at least one other encrypted block within the encrypted segment; and supplying low level data units to a physical layer that handles physical communication over the network, at least some of the low level data units each including a plurality of encrypted segments.
