… two-hop communication scenario, we shall consider each node to be half-duplex, which leads
to a two-phase communication … be the enabler of secure communication. By recruiting the …

… In this two-hop communication scenario, where the cooperation from the relay node is …
In essence, this paper shows that a cooperative jammer enables secure communication to …

… secure transmission assisted by a buffer-aided energy harvesting relay. Therefore, to answer
the above questions, we study secure transmission in a two-hop … problem for two cases. In …

… We consider a half-duplex two-hop relaying network composed of a source (Alice), a destination
(… In order to focus on the impact of link selection policies on the security performance, we …

… two-hop communication has long been studied in fault-tolerant algorithms in computer science.
We propose two … requirements on resources for communication and the structures of the …

… secure two-hop relay … two wireless-powered two-hop relaying schemes for improving
secrecy capacity in the presence of an eavesdropper. The proposed schemes are based on two …

… We consider a half-duplex two-hop secure communication link as depicted in Fig. 1. In this
model, source S wishes to send information to the destination D securely with the help of a …

… (partial P1A ), the communication is forward secret if a forward secure cipher suite is used …
was designed for two parties P4 ; (2) the same key is used for encryption on each “hop” in the …

… We consider a two-hop four-terminal … both hops. The key idea is that Alice and Bob can
help form a cooperative jamming system without the addition of extra helpers outside the two-hop …

… We show that a pairwise key established between two nodes using our protocol is secure …
For example, for nodes that are one hop or two hops away, they can find multiple disjoint …
