Joint subcarrier and power allocation is carefully considered to meet the secure requirements of the cooperative OFDMA network.
For example, given two data streams x and y, based on weakly secure requirements, the attacks allow to get the combination value of x ⊕ y, but not x or y alone, while in Shannon secure, the attacks disallow learning neither of them.
This chapter introduces a Wireless Integrated Secure Data Options Model (WISDOM) that provides three tiered security options, with proper hardware, software, and security requirements delineated to secure a wireless local area networks (WLAN) at a corresponding security level equivalent to the wired network with which it connects.
Finally, we prove the proposed scheme is secure based on several security requirements, and justify its performance by concrete implementations.
This paper proposes an integrated development process suitable for the secure development requirements and system security requirements described by various regulatory bodies.
To be "perfectly secure", the requirement of the mutual information I(M X)=0 must be satisfied between Alice's information message M and the transmitted word X.
Besides, both the secure communication requirement and the lowest electrical energy storage threshold at IR must be guaranteed in our formulated optimization problem.
We aim to, under the constraints of secure communication requirement and the lowest electrical energy storage threshold at IR, maximize the minimum harvested energy among the multi-antenna ERs by jointly optimizing the transmit beamforming vectors, AN covariance, and power splitting ratio.
As one of the physical layer security technologies, cooperative jamming often requires collaborative nodes to actively cooperate with other nodes with secure communication requirements to transmit information.
