    The extended Kalman filter algorithm and unscented Kalman filter algorithm have a bad estimation performance of chaotic system state and parameter in secure communication based on chaotic parameter modulation.To solve this problem,the particle filter algorithm was used to estimate the state and parameter. The sent binary symbols were used to modulate the parameters of chaotic systems in transmitter. The corresponding parameters of chaotic systems were estimated through particle filter with received signal in receiver. The simulations show that in comparison with extended Kalman filter and unscented Kalman filter, particle filter algorithm in chaotic parameter estimation has shorter convergence time and lower estimation error, and the secure communication can be realized more effectively.

     A simple synchronization method by only transmitting a single driving variable for a new Lorenz-like attractor is proposed. Furthermore, based on the chaotic synchronization method, a secure communication system is proposed. Since chaos synchronization can be achieved by transmitting only one channel information contains a single variable from driving system to response system, this method is more practical. Theoretical deduction and computer simulation show the effectiveness of the proposed method.

    Correctness is a key attribution for software trustworthiness. Abstractly, it can be represented by whether or not the implementations of the software satisfys its specification. Meanwhile, the correctness is also related to its execution environment. On the other hand, the correctness is a course of modifying implementation, i.e., the software is more and more close to correctness. In order to describe the dynamic correctness of software, the abstract characterization of dynamic correctness is proposed based on two-third bisimulation. Firstly, two-thirds limit bi-simulation is defined which reflects the course of modification implementation. Secondly, two-third bisimulation limit is presented which means that the specification of a software is the limit of its implementations. Finally, some algebraic properties are proved.

    How to guarantee the security of private data is a very important problem in electronic commerce. A resilient and distributed scheme of data security was proposed in this paper. The scheme introduced additive sharing and secret sharing technologies to improve the security of information content. The information data was stored among the total servers distributedly by additive sharing. At the same time, each information share was backed up among the servers set. Therefore, if an adversary could not corrupt more than quorum number of servers, he could not obtain the information data. The scheme has a nice resilient ability. It means servers can join or leave the servers group freely and the threshold value can be changed dynamically, which is especially useful in the circumstance where the ability of attacker is alterable.

    In wireless sensor networks(WSN), FEC error control strategy cannot overcome the problem of package loss,and it is also low in energy effiency when transmitting long data. The main indicator of the traditional ARQ error control strategy is bandwidth-delay product, rather than the energy efficiency. An ARQ error control strategy is presented based on the received signal strength indicator(RSSI) in this paper, which adjusts the maxRetries and retryDelay of ARQ dynamicly. The sender extracts the present channel RSSI value from data request frame when the data request is accepted. If the RSSI value is overhead the threshold,it adopts small maxRetries and retryDelay, else, it increases the maxRetries and selects a larger retryDelay randomly. Therefore, it can avoid the sender getting into busy waiting and enhance the probability of correctly received package of the receiver. Experimental results show that the proposed scheme can decrease the package loss probability effectively and is better in energy efficiency.

     Aiming at how to improve the packet marking markup information and the efficiency and accuracy of path reconstruction, an improved scheme is proposed based on PPM. The proposed scheme records routing information into the option of IP header to improve the packet marking markup information. A TTL1 field and a filling coefficient α were increased to respectively record the hops from the first router of mark packets to victim and identify authenticity of marked packets. Experiments show that improved packet marking algorithm greatly decreases the number of desired marked packets. When victim reconstructs path, it can effectively identify the authenticity of marked packets and improve the efficiency and accuracy of path reconstruction.

    With increasing serious situation of network security and network defects in the agreement itself, it’s incompetent to use the traditional way of firewall. Fuzzy neural network model of integrated intrusion detection is proposed to improve the ability of intrusion prevention in network. First, the data stream is obtained from network, and the fuzzy approach is used to perform data pre-processing on characteristics of invasion. Then, the training and testing data is received by the integrated fuzzy neural network module from the data pre-processing module. Through repeated training and learning, the weights of nodes in the sub-trees converge to determine values. When training is completed, the model is used to detect the network data. The response module receives the results of fuzzy neural network module and makes the appropriate response. In the experiment, the network intrusion detection datasets, a part of KDDCUP99, are used to evaluate integrated fuzzy neural network, and compared to a single neural network model. On the whole,the result shows that fuzzy neural network ensemble method results is more stable. It was slightly reduced on false alarm rate, false negative rate and false positive rate and significantly improved on accuracy and ability of datasets generalization.

    In order to solve constrained optimization problem, a dynamic multi-swarm particle swarm optimizer (DMCPSO) is proposed. In DMCPSO, dynamic multi-swarms and comprehensive learning strategy are applied to improve the swarm diversity. On the basis of the idea “no talent is to be wasted” from human society, each sub-swarm selects its member to the maximum utility of each particle, and the dynamic mutation operator is adopted for best performing particle (Gbest) to improve the ability of escaping from local optima. Experimental simulation results of benchmark functions show that DMCPSO achieves better solutions than other algorithms.
