  • Secure network coding for multi-resolution wireless transmission
    Patent number: 9923714
    Abstract: Described herein is a method and system for hierarchical wireless video with network coding which limits encryption operations to a critical set of network coding coefficients in combination with multi-resolution 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.
    Type: Grant
    Filed: August 10, 2015
    Date of Patent: March 20, 2018
    Assignees: Massachusetts Institute of Technology, Universidade Do Porto, Telefonica, S.A.
