Physical layer security in wireless networks : design and enhancement
Security and privacy have become increasingly significant concerns in wireless communication networks, due to the open nature of the wireless medium which makes the wireless transmission vulnerable to eavesdropping and inimical attacking. The emergence and development of decentralized and ad-hoc wireless networks pose great challenges to the implementation of higher-layer key distribution and m...
متن کاملWireless Physical Layer Security
Security in wireless networks has traditionally been considered to be an issue to be addressed separately from the physical radio transmission aspects of wireless systems. However, with the emergence of new networking architectures that are not amenable to traditional methods of secure communication such as data encryption, there has been an increase in interest in the potential of the physical...
متن کاملPhysical Layer Security for Multiuser MIMO Communications
Wireless multi-user MIMO communications are used more and more often to exchange sensitive data. Because of the broadcast nature of the physical medium, unauthorized receivers located within the transmission range can observe the signals sent by the transmitter to a legitimate receiver and eavesdrop them. Therefore, security has become an extremely important issue to deal with. Multiuser MIMO c...
متن کاملSecurity Analysis of a Hash-Based Secret Sharing Scheme
Secret sharing schemes perform an important role in protecting se-cret by sharing it among multiple participants. In 1979, (t; n) threshold secret sharing schemes were proposed by Shamir and Blakley independently. In a (t; n) threshold secret sharing scheme a secret can be shared among n partic-ipants such that t or more participants can reconstruct the secret, but it can not be reconstructed b...
متن کاملPhysical-Layer-Enhanced Wireless Secret Key Exchange
We address the problem of efficiently establishing a shared secret key over an open wireless channel in the presence of an active (jamming) adversary. A commonly employed technique in practice for key sharing is the cryptographic ellipticcurve Diffie-Hellman (DH) protocol; however, its communication cost in a jammed environment is very high. Hence, we employ novel physical-layer techniques to e...
