Mission-critical communications (MCC) involve all between people in charge of the safety civil society. MCC have unique requirements that include improved reliability, security and group communication support. In this paper, we propose secure robust Multiple-Input-Multiple-Output (MIMO) transceivers, designed for multiple Base Stations (BS) supporting multicast presence eavesdroppers. We formul...

Millimeter-wave (mmWave) communications are highly promising to improve the capacity of modern wireless networks, while physical layer security (PLS) techniques hold great potential enhance critical secrecy performance therein. By carefully exploiting significant signal difference between Non-Light-of-Sight (NLoS) and Line-of-Sight (LoS) mmWave links, this paper proposes a Sight-based Cooperati...

This paper proposes a robust privacy-preserving secure anonymous zone routing protocol for military tactical networks. Since much of works have been focused on secure anonymous communications in either reactive protocols or proactive protocols, no research has been dedicated to the secure anonymous hybrid routing protocol. In particular, we propose the hybrid routing location-centric communicat...

-For Privacy Preserving Communications Both Anonymity and end to end encryption mechanism is essential. Identity Based Encryption technique is best suitable for secure and anonymous communications. For solving anonymous and secure communication problems both cryptographic and IBE based protocols needed which governs the proper communication between two parties. For the purpose of authentication...
