The authentication error in Two-Hop wireless networks is considered without knowledge of eavesdropper channels and location. This paper presents an eavesdropper model with authentication error and two eavesdropping ways. In the model, the authentication error is expressed a pair(p_1, p_2). Based on the authentication error, a cooperative transmission protocol against impersonation attack is presented. Then, the number of eavesdroppers can be tolerated is analyzed while the desired secrecy is achieved with high probability in the limit of a large number of relay nodes. Final, we draw two conclusions for authentication error: 1) the impersonate nodes are chosen as relay is the dominant factor of the transmitted message leakage, and the impersonation attack does seriously decrease the number of eavesdroppers can be tolerated. 2) The Error authentication to legitimate nodes is almost no effect on the number of eavesdroppers can be tolerated.
Here we report a controllable four DNA sub-tiles, self-assembling into 4-arm DNA tiles, under control of a DNA strand displacement based on DNA sequential circuit. The motif is encoded, compiled and simulated successi...

A chemical system for facile and accurate detection of 2,4-dichlorophenol (DCP) via iron (Ⅱ) phthalocyanine (Fe(Ⅱ)Pc) catalyzed chromogenic reaction is reported for the first time. In this system, DCP could be oxidized by dioxygen with the catalysis of Fe(Ⅱ)Pc and then coupled with 4-aminoantipyrine (4-AAP) to generate pink antipyrilquinoneimine dye. control experiments showed that the addition of ethanol could obviously enhance the catalytic activity of heterogeneous Fe(Ⅱ)Pc catalysts because of the partial dissolution of Fe(II)Pc nanocubes, which was confirmed by the SEM analysis. On the basis of the detection results of DCP in the range from 2×10^-5 to 9×10^-4 mol/L, we obtained a regression equation (A = 0.187 5 + 0.01 209C (R2=-0.995 6)) with the detection limit (3σ) of 3.26×10^-6 mol/L, which could be successfully used in detecting the real samples.
The ultra-weak luminescence (UWL) feature of plant seeds is investigated. Before UWL measurement, the maize seeds are moistened in distilled water for various periods, which are 2h, 4h, 6h and 8h. And then the seeds a...
