  1. A novel and efficient lattice-based authenticated key exchange protocol in C-K model

    In this proposal, two novel lattice-based authenticated key exchange (LB-AKE) protocols, (1) using a signature-based authenticator and (2) using a signcryption-based authenticator, are devised in Canetti-Krawczyk proof model. The security of proposed protocols depends on the hardness of small integer solutions on the lattice. An extensive proof of security to our claim is given. The proposed AKEs characterize faster computation speed and resistance to the modern complex computers.

  2. Physical layer security for dual-hop FSO/RF system using generalized ΓΓ/ημ fading channels

    In this paper, we present a mixed FSO/RF network following generalized ΓΓ/ημ fading channels. Here, the decode-and-forward relaying protocol is used for conveying the message from source(s) to the legitimate receiver (m) in the co-existence of an eavesdropper (e). Therefore, for obtaining secured communication link, we apply the physical layer security analysis and derived secrecy parameters in terms of secrecy capacity and secrecy outage probability.

  3. Internet delay forecasting for correlated and uncorrelated scenarios

    In this paper, we propose a novel forecasting algorithm, which, in contrast to those reported previously, is suitable for both the correlated and the uncorrelated delay scenarios. The proposed algorithm is compared with other methodologies by using standardized delay traces reported in the literature, and it is shown that the proposed algorithm obtains an improved performance with smaller errors than those of current predictors.

  4. Channel characterization of EM waves propagation at MHz frequency through seawater

    This key figure represents Pr(dBm) for multiple SeaWater depths that shows transmission range d (meters) of EM waves in SeaWater based on J. Lucas approach (encapsulated antenna with deionized water into an insulator). That shows if insulated encapsulation length is 5 m (≈dRayleigh), then for that much distance, Pr (dBm) remains approximately constant. Overall range lies approximately between 50 and 300 m. Estimated Pr (dBm) using real time data averaged between 1955 and 2012 also helped us to analyze that as we saw in literature it faces sudden exponential decay; these results indicates negation of sudden exponential delay (in general) of Pr (dBm) in SeaWater; it was only possible by assuming constant SeaWater ε (F/m) and σ

    (S/m).

  5. Towards green computing in wireless sensor networks: Controlled mobility–aided balanced tree approach

    This paper proposes a green computing framework lifetime maximization based on balanced tree node switching. Two node-shifting algorithms are developed, namely, energy-based shifting and load-based shifting for balancing tree-based network in terms of energy. Analytical and simulation experiment–based comparative performance evaluation attests the benefit of the proposed framework as compared to the state-of-the-art techniques considering a number of energy-oriented metrics for wireless sensor networks.
