متن کاملPreventing Pollution Attacks in Multi-source Network Coding
Network coding is a method for achieving channel capacity in networks. The key idea is to allow network routers to linearly mix packets as they traverse the network so that recipients receive linear combinations of packets. Network coded systems are vulnerable to pollution attacks where a single malicious node floods the network with bad packets and prevents the receiver from decoding correctly...
متن کاملSecurity Analysis on "An Authentication Code Against Pollution Attacks in Network Coding"
We analyze the security of the authentication code against pollution attacks in network coding given by Oggier and Fathi [1] and show one way to remove one very strong condition they required. Actually, we find a way to attack their authentication scheme. In their scheme, they considered that if some malicious nodes in the network collude to make pollution in the network flow or make substituti...
متن کاملAn Efficient Short Null Keys Based Scheme for Securing Network Coding Against Pollution Attacks
Network coding has gained wide attention nowadays for its significant advantages on many aspects compared with traditional routing mechanism. However, if there are malicious nodes launching pollution attacks by tampering or forging data packets in the communication network, the sink nodes will suffer from failure decoding, together with serious results such as bandwidth wasting, longer transmis...
متن کاملA On the Practicality of Cryptographic Defenses against Pollution Attacks in Wireless Network Coding
Numerous practical systems based on network coding have been proposed in recent years demonstrating the wide range of benefits of network coding such as increased throughput, reliability, and energy efficiency. However, network coding systems are inherently vulnerable to a severe attack, known as packet pollution, which presents a key obstacle to the deployment of such systems. Several cryptogr...
