Enhancement of FTP-NDN Supporting Nondesignated Receivers

Recently, Fan et al. proposed the File Transfer Protocol Based on Re-Encryption for Named Data Network (FTP-NDN) in order to reduce the cost that affects simultaneous access of same video services. The authors designed an elegant network architecture to deal with secure file transmission to the unknown potential customers. The technique is shown to be secured under Decisional Bilinear Diffie-Hellman (DBDH) assumption and computationally efficient than other existing techniques. Although, the protocol achieves data confidentiality, it does not provide node authentication during transmission in the NDN. In this paper, we propose an authentication scheme using the bilinear pairing. Performance evaluation shows that the proposed technique can be incorporated with considerable computation overhead.
