Linear network coding (LNC) is a promising technology that can increase network throughput, improve transmission robustness and provide data confidentiality. In this paper, we investigate the optimal transmission topology construction and LNC design for secure multicast, i.e., the Integer Secure Multicast (ISM) problem. The ISM problem aims to find the transmission topology with integral link rates...
Linear network coding (LNC) has great advantages in optimizing throughput, balancing network load, increasing robustness, etc. Since the coded data packets transmitted in the network are linear combinations of original data packets, the attacker cannot decode to obtain the original data when it cannot acquire enough coded data packets. Therefore, LNC can also provide efficient information security...
The continuous growth of media-rich content calls for more efficient and secure methods for content delivery. In this paper, we will address the optimal linear network coding (LNC) design for secure unicast streaming against passive attacks, under the requirement of information theoretical security . The objectives include 1) satisfying the information theoretical security requirement, 2) maximizing...
Linear network coding (LNC) has attracted significant attention because it has the potential to achieve the throughput capacity of a network. However, transmission systems with LNC are vulnerable to pollution attacks in which normal packets will be corrupted by malicious relay nodes and participate in normal encoding process. The null keys based error detection schemes have been designed to efficiently...
In recent years network coding has attracted significant attention in telecommunication. The benefits of network coding to a communication network include the increased throughput as well as secure data transmission. The purpose of this work is to design secure linear network coding against wiretap attack. The problem is to maximize the transmission data rate of multiple unicast streams between a...
