A Secure Data Transmission Scheme Based on Information Hiding in Wireless Sensor Networks
Baowei Wang,Hongwei Qian,Xingming Sun,Jian Shen,Xiaoyu Xie 보안공학연구지원센터 2015 International Journal of Security and Its Applicat Vol.9 No.1
Wireless sensor networks hold the promise of facilitating large-scale and real-time data processing in complex environments, therefore the security is a critical issue that must be resolved. In order to prevent attacks by adversaries with fake identities, we propose a secure data transmission scheme based on information hiding technique. Firstly, one superficial change made to the beacon message of original CTP is to mark the unique identity infor-mation of a sensor node. Secondly, sensitive information is uniformly and randomly embed-ded into the ordinary data by using the space-efficient randomized data structure characteris-tic of Bloom Filter. Experimental results and performance analysis demonstrate that the pro-posed scheme can efficiently detect the malicious node with fake identities through the sensi-tive information. On the other hand, our scheme can protect the sensitive information without affecting the transmission and usability of the ordinary data.

In this paper we consider finite element mathods for nonlinear parabolic problems defined in Ω ⊂ R^(d) (d ≤ 4). A new initial approximation is taken. Optimal order error estimates in L_(p) for 2 ≤ p ≤ ∞ are established for arbitrary order finite element. One order superconvergence in W^(1.p) for 2 ≤ q ≤ ∞ are demonstrated as well.

In Arabidopsis, trichome formation is regulatedby a MYB-bHLH-WD40 (MBW) transcriptional activatorcomplex, which can activate the expression of GLABRA2(GL2) and R3 MYB genes. GL2 is required for trichomeformation, whereas R3 MYBs inhibit trichome formation byblocking the formation of the MBW complex, thus inhibitingthe expression of GL2. By using the amino acid sequence of theArabidopsis R3 MYB transcription factor TRICHOMELESS1(TCL1) to BLAST the soybean (Glycine max) protein database,we found that there are a total of six R3 MYB genes insoybean, namely Glycine max TRICHOMELESS1 through 6(GmTCL1-GmTCL6). By generating transgenic plants, wefound that trichome formation in soybean plants overexpressingeach of the GmTCLs remained largely unchanged, and theexpression of putative GL1 and GL2 genes in the transgenicplants was unaffected. However, all the GmTCLs interactedwith GLABRA3 (GL3) in transfected Arabidopsis protoplasts,expression each of the GmTCLs in Arabidopsis inhibitedtrichome formation, and the expression levels of GL1 andGL2 were greatly reduced in the Arabidopsis transgenicplants. Moreover, phenotypic complementary analysis showedthat GmTCL1 is functionally equivalent to TCL1. Takentogether, these results suggest that GmTCLs are functionalR3 MYBs, however, they do not regulate trichome formationin soybean.

Objective: To evaluate microstructural damage in high myopia (HM) patients using 3T diffusion kurtosis imaging (DKI). Materials and Methods: This prospective study included 30 HM patients and 33 age- and sex-matched healthy controls (HCs) with DKI. Kurtosis parameters including kurtosis fractional anisotropy (FA), mean kurtosis (MK), axial kurtosis (AK), and radial kurtosis (RK) as well as diffusion metrics including FA, mean diffusivity, axial diffusivity (AD), and radial diffusivity derived from DKI were obtained. Group differences in these metrics were compared using tract-based spatial statistics. Partial correlation analysis was used to evaluate correlations between microstructural changes and disease duration. Results: Compared to HCs, HM patients showed significantly reduced AK, RK, MK, and FA and significantly increased AD, predominately in the bilateral corticospinal tract, right inferior longitudinal fasciculus, superior longitudinal fasciculus, inferior fronto-occipital fasciculus, and left thalamus (all p < 0.05, threshold-free cluster enhancement corrected). In addition, DKI-derived kurtosis parameters (AK, RK, and MK) had negative correlations (r = -0.448 to -0.376, all p < 0.05) and diffusion parameter (AD) had positive correlations (r = 0.372 to 0.409, all p < 0.05) with disease duration. Conclusion: HM patients showed microstructural alterations in the brain regions responsible for motor conduction and visionrelated functions. DKI is useful for detecting white matter abnormalities in HM patients, which might be helpful for exploring and monitoring the pathogenesis of the disease.
