As the reason of image encryption algorithm of high iteration and low-key encryption-dimensional discrete chaotic space, this paper proposed a CAT methodology combining Chaos to discrete images. The using of map cyclical changes in the image is encrypted by different-sized images of different encryption cycle. After experiments the results show that this encryption algorithm using Chaos and CAT can effectively encrypt images. This algorithm can also obtain the best parameters to achieve the best image encryption effect.

Search engines nowadays are becoming more and more necessary and popular in surfing the Internet. However, how these search engines like Google or Baidu works is unknown to many people. This paper, through a research into Open-source search engine Nutch, introduces how a common search engine works. By using Nutch, a search engine which belongs to Guizhou Normal University's website is designed and at last, through the improvement of Nutch's sorting algorithm and experiment, it can be found that Nutch is very suitable for working in home-search.

The author puts forward a ring-based routing approach, which reduces the load of the mechanism of the central node in a wireless mesh network. This routing mechanism can evenly allocate the load from the area close to the center of the network to the network perimeter area. This paper analyzes the ring-based routing method from the outlined principles, method descriptions and emulation of the method. Adopting of this time scheduling approach is mainly to save energy, so the network can significantly decrease average power consumption, but the average power consumption reduction is based on the cost of network latency, because the dormant node cannot forward the packet. It cannot continue working until the corresponding super-frame period arrives.

The adaptive-network-based computational verb inference system (ANCVIS) is a kind of computational verb inference system implemented in adaptive networks. In this paper, a new type of ANCVIS, which uses trend-based computational verb similarities, is presented, and its learning algorithm is derived. Simulations show that the proposed model can tune system parameters well and yield reasonable results based on computational verb rules and input-output data pairs.

Different from the conventional hysteretic comparators, a simple circuit is introduced to provide flexibility to program the hysteretic threshold in this paper. The hysteresis can be controlled accurately at a large range and equals to the difference of extra controlled voltage to make the hysteresis be controlled expediently. Besides, this structure is not only for low power dissipation comparators but also for high speed comparators.

File sharing is one of the most typical applications in P2P networks. Due to the problems of certificate management and key escrow, the traditional public key cryptosystems including PKI and ID-PKC are very difficult to be applied in the P2P networks. Identity authentication is always hard to be brought into effect, which brings some trust problems, such as free riding. The trust problems widely exist in such file sharing systems. In this paper, we research the applications with identity certification based on certificateless public key cryptography (CL-PKC), and build a file sharing system based on the JXTA platform in the P2P networks. The system implements key generation, identity authentication and file content authentication, verifies its feasibility and validity, and proves that it is so secure.

Computational verb cellular networks (CVCNs) are new kinds of cellular computational platforms where cellular rules are computational verb rules. In the previous works, the categorizations of patterns formed in two-dimensional computational verb networks (2D CVCNs) were done. The existing results imply that 2D CVCNs are universal in pattern formations in the sense that all patterns that reported in other color cellular networks including color cellular automata (CA) and cellular neural networks (CNN) can be observed in 2D CVCNs. In this paper some new kinds of patterns like Turing patterns and other dynamical pattern are presented.
