PATTERN mapping ON BETA-SPLINE SURFACES——bilinear mapping METHOD

Computer Aided Drafting,Design and Manufacturing 1992年第2期3卷 27-31页

作者： Zhang Mandong Zhao Hongsheng Guan Rongchang Taiyuan University of Technology Taiyuan 030024, P. R. China

Texture pattern mapping is one of the most important techniques for high quality image syn- thesis. It can largely enhance the visual richness of raster-scan images. In this paper is presented a new method of mapping planar texture pattern onto beta-spline curved surfaces——bilinear mapping method which can map planar texture pattern onto curved surfaces with less distortion, and also can fulfill the geometric transformation of the texture pattern on the curved surfaces by operating the pattern win- dow. It is valuable to both CAD/CAM in artistic field and computer graphics.

The terminals in mobile cloud computing have themselves the special characteristics, such as mobile flexibility, distributed in different domains, resourceconstraint and easily to be captured et al. The terminals in mobile cloud computing participated the collaborative computing, information exchange and sharing secrets may come from different domains, different networks or different clouds. For this complex network environment the paper proposes a Multi-domain lightweight Asymmetric group key agreement(ML-AGKA). It adopts the bilinear mapping and blind key technology to achieve an asymmetric group key agreement protocol among mobile terminals distributed in different domains, proposes a computation and communication migration technologies to ensure that the mobile terminals are lightweight computing and communication consumption. The protocol can also achieve anonymity and authentication. The protocol is proven secure under the Computational Diffe-Hellman(CDH) problem assumption and the performance analysis shows that the proposed protocol is highly efficient.

Security has been regarded as one of the hardest problems in the development of cloud computing. This paper proposes an AllianceAuthentication protocol among Hybrid Clouds that include multiple private clouds and/or public clouds. Mu tual authentication protocol among entities in the IntraCloud and InterCloud is proposed. Blind signature and bilinear mapping of automorphism groups are adopted to achieve the InterCloud Alli anceAuthentication, which overcome the complexi ty of certificate transmission and the problem of communication bottlenecks that happen in tradi tional certificatebased scheme. Blind key, instead of private key, is adopted for register, which avoids
