High-performance hardware architecture of elliptic curve cryptography processor over GF（2^163）

We propose a novel high-performance hardware architecture of processor for elliptic curve scalar multiplication based on the Lopez-Dahab algorithm over GF（2^163） in polynomial basis representation. The processor can do all the operations using an efficient modular arithmetic logic unit, which includes an addition unit, a square and a carefully designed multiplication unit. In the proposed architecture, multiplication, addition, and square can be performed in parallel by the decomposition of computation. The point addition and point doubling iteration operations can be performed in six multiplications by optimization and solution of data dependency. The implementation results based on Xilinx VirtexⅡ XC2V6000 FPGA show that the proposed design can do random elliptic curve scalar multiplication GF（2^163） in 34.11 μs, occupying 2821 registers and 13 376 LUTs.     

Role of recognition of prior learning for emerging economies: learning from a four sector pilot project in India

Recognition of prior learning (RPL) has increasingly been recognised as a useful way to certify experience and competencies gained in the workplace informally. Particularly pertinent is RPL in the context of international migration or in economies, where system reforms seek to overcome challenges related to access to formal training and qualifications. India has the goal to skill 300 million of its growing workforce and provide them access at various levels to certification and further learning opportunities. As a part of the overall system reforms, the Government of India, jointly with the ILO, pilot tested RPL in four sectors in collaboration with the industry and built the foundation for wider replication for another 26 growth sectors by undertaking a tracer study and evaluation. This paper can empirically establish that RPL has had a positive effect on income opportunities, occupational safety, social status and openness to further learning. The paper further discusses the challenges encountered during the implementation of the RPL projects before concluding with recommendations, highlighting the aspects required for quality RPL in an emerging economy. It closes by emphasising the importance of conducting tracer studies to determine impact and the need to provide complementary training during the RPL process.

初论NGO与中国群众体育发展的结合

缺少活动场地、活动经费、社会体育指导员等,这些因素都成为了制约我国社会体育进一步发展的瓶颈.而这些问题恰恰又是"政府"、"民间"这两种社会体育形式的症结所在."官办"社会体育不堪重负,必须解放;"民间自发组织"太过松散不利发展,需要革新.NGO作为一种非政府性组织,它的界于紧凑型(政府)和松散型(民间自发)两种社会体育模式的特性,是通向组织多元化的途径,也是解决我国现行社会体育模式弊端的有效方式.     

民族地区社会组织发展农村经济的实证分析——以广西那坡和平村养殖协会为例

创新社会管理是当前我国社会发展的热点,也是众多学者关注的焦点。民族地区农村由于地理与历史等综合因素,经济发展相对滞后。充分发挥民族地区基层社会组织的自治力量,转变经济发展方式,促进农民增收是我国农村发展的必然趋势。广西那坡和平养殖协会以“党委＋协会＋农户”的运行机制开展“五统一”活动,大力发展了地方经济,推动了农村社会的和谐稳定发展。同时,也在参与发展农村经济中获得了基层社会再组织化、与基层政府合作互动、相关群体利益协调等宝贵经验,为民族地区社会组织参与社会村庄建设与治理提供了可行路径。     

Iris Localization Algorithm Based on Improved Generalized Symmetry Transform

Accuracy and fastness of iris localization are very important in automatic iris recognition. A new fast iris localization algorithm based on improved generalized symmetry transform (GST) was proposed by utilizing iris symmetry. GST was improved in three aspects: 1 ) A new distance weight function is defined. The new weight function, which is effective in iris localization, utilized the characteristic of irises that the iris is a circular object and it has one inner boundary and one outer boundary. 2) Each calculation of the symmetry measurement of a pair of symmetry points was performed by taking one point of a pair as the starting point of the transformation. This is the most important reason for fast iris localization, due to which, repetitious computation was largely excluded. 3) A new phase weight function was proposed to adjust GST to locate circle target much better because the inner part of iris is darker than the outer part. The edge map of iris image was acquired and GST was only implemented on the edge point, which decreased computation without loss of accuracy. The modification of distance weight function and phase weight function leads to the accuracy of localization, and other ideass peed up the localization. Experiments show that the average speed of new algorithm is about 7.0-8.5 times as high as traditional ones including integro-differential operator and Hough transform method.
