Wireless networks are increasingly being employed to transfer highly sensitive information. Due to the broadcast nature of wireless channels, security issues have been taken as a critical role in wireless communications. A promising direction toward achieving secure wireless communications is physical-layer security, which is an approach exploiting the randomness of wireless channels to ensure secrecy...
In this paper, the recent research on secure transmission of network coding in wireless networks is reviewed. Security risks have become a major problem to the development of wireless networks, and network coding is the development trend of next generation secure networks. Firstly, the brief concept of network coding is introduced. Secondly, up to date related research on secure network coding in...
Key management in wireless sensor networks is a challenging problem because asymmetric key cryptosystems are unsuitable in resource constrained sensor nodes, and also because sensor nodes could be physically compromised by adversaries. Motivated by a key agreement scheme proposed by Leighton and Micali (LM-KDS), we present a secure key pre-distribution scheme, called random LM-KDS (R-LM-KDS), which...
