With the development of computer and enterprise in formalization, enterprises depend more and more on a physical platform to realize sharing information resource and business collaboration. In order to achieve business processes and data process automation, more and more enterprises come to study the contact between data flow. This paper mainly introduced an enterprise service system based on Internet SOA. It summarized enterprise networking integration technology in detail from system analysis to model establishment and the final language design. It reduced sensitivity of enterprise and greatly reduced investment cost of enterprises. It provided a new research direction for us to better realize the sharing of enterprise information resource and service. © 2013 Springer-Verlag Berlin Heidelberg.

Magnetoelectric (ME) coupling by acoustic waveguide was developed. Longitudinal and transversal ME effects of larger than 44 and 6 (V cm-1 Oe-1) were obtained with the waveguide-coupled ME device, respectively. Several resonant points were observed in the range of frequency lower than 47 kHz. Analysis showed that the standing waves in the waveguide were responsible for those resonances. The frequency and size dependence of the ME effects were investigated. A resonant condition about the geometrical size of the waveguide was obtained. Theory and experiments showed the resonant frequencies were closely influenced by the diameter and length of the waveguide. A series of double-peak curves of longitudinal magnetoelectric response were obtained, and their significance was discussed initially. © 2016 Elsevier B.V. All rights reserved.

Blind signature and proxy signature are very important technologies in secure e-commerce. In this paper, motivated by the lattice basis delegation technique, we propose a proxy blind signature scheme based on the hard problems of lattice. To the best of the authors' knowledge, our construction constitutes the first proxy blind signature scheme from lattices, which is believed secure in the postquantum environment.

Under the hard assumption of SIS (Short Integral Solution), we construct the first lattice-based identity-based proxy signature scheme in bonsai tree model, which based on the bonsai tree signature scheme,the proxy signature scheme in this paper has unforgeability of proxy key, revocability of proxy signature and existentially unforgeability of signature.

Mobile computing environment is relatively complex, and the structure dynamic degree is high, and the heterogeneous is changeable. Therefore, the development of mobile network based on web techniques must be adapted to the complex environment. In order to get a better network structure supporting mobile computing, based on the context aware consciousness theory, combined with the VC programming software, we design the algorithm of mobile computing network node, obtain the spatial statistical node model of mobile network, and use GPRS/3G base station to establish mobile network model based on the core of multimedia services. In order to verify the effectiveness and reliability of mobile computing algorithm, we calculate the network performance using VC programming software, obtain the network data transmission and delay results, and use mobile algorithm to develop multimedia licensing scheme. It provides a new algorithm for researching on mobile computing. © (2014) Trans Tech Publications, Switzerland.
