Network coding has been proposed to be built into Named Data Networking (NDN) for achieving efficient simultaneous content delivery. Network coding allows intermediate nodes to perform arbitrary coding operations on Data packets. One salient feature of NDN is its content-based security by protecting each Data packet with a signature signed by its publisher. However, in the network coding-based NDN, it remains unclear how to securely and efficiently sign a recoded Data packet at an intermediate router. This work proposes a mechanism to enable linearly homomorphic signatures in network coding-based NDN so as to directly generate a signature for a recoded Data packet by combining the signatures of those Data packets on which the recoding operation is performed.
