Abstract
Described herein is a method and system for wireless data transmission with network coding which limits encryption operations to a critical set of network coding coefficients in combination with multi-resolution and/or multi-description video coding. Such a method and system achieves hierarchical fidelity levels, robustness against wireless packet loss and efficient security by exploiting the algebraic structure of network coding.
