Physical-Layer Security over Correlated Erasure Channels
W. K. Harrison, J. Almeida, S. W. McLaughlin +1
We explore the additional security obtained by noise at the physical layer in a wiretap channel model setting. Security enhancements at the physical layer have been proposed recent…
Coding for Cryptographic Security Enhancement using Stopping Sets
W. K. Harrison, J. Almeida, S. W. McLaughlin +1
In this paper we discuss the ability of channel codes to enhance cryptographic secrecy. Toward that end, we present the secrecy metric of degrees of freedom in an attacker's knowle…
Algebraic Watchdog: Mitigating Misbehavior in Wireless Network Coding
MinJi Kim, Muriel Medard, Joao Barros
We propose a secure scheme for wireless network coding, called the algebraic watchdog. By enabling nodes to detect malicious behaviors probabilistically and use overheard messages…
A Multi-hop Multi-source Algebraic Watchdog
MinJi Kim, Muriel Medard, Joao Barros
In our previous work "An Algebraic Watchdog for Wireless Network Coding", we proposed a new scheme in which nodes can detect malicious behaviors probabilistically, police their dow…
Network Coding Security: Attacks and Countermeasures
Luísa Lima, João P. Vilela, Paulo F. Oliveira +1
By allowing intermediate nodes to perform non-trivial operations on packets, such as mixing data from multiple streams, network coding breaks with the ruling store and forward netw…
Lightweight Security for Network Coding
Joao P. Vilela, Luisa Lima, Joao Barros
Under the emerging network coding paradigm, intermediate nodes in the network are allowed not only to store and forward packets but also to process and mix different data flows. We…
