Abstract

In a system that transmits frames of data as a stream of packets, packet header information is augmented with localizing data that serves to distinguish frame header information and frame data of each frame within the stream of packets. The localizing data facilitates encryption of the frame data at the packet level without encrypting the frame header information, and subsequent decryption of the encrypted data within the stream of data.
