A MULTICAST KEY MANAGEMENT SCHEME BASED ON CHARACTERISTIC VALUES OF MEMBERS

A new collusion attack on Pour-like schemes is proposed in this paper. Then, we present a collusion-free centralized multicast key management scheme based on characteristic values of members. The re-keying method that other group members calculate new keys when a member is joining or leaving is also designed. It achieves forward secrecy and backward secrecy. Compared with typical existing centralized schemes, the storage of Group Key Controller (GKC) in our scheme halves the storage overhead of others, and communication overhead of GKC is 2 in case of joining re-keying. Especially, the leaving re-keying overhead is and the overall performance is excellent.

A Review on the Role of Risk Management (RM) and Value Engineering (VE) Tools for Project Successful Delivery

Both in developed and in developing countries, the construction industry is regarded as an economic investment activity without forgetting its significant relationship with national economic development due to its great contributions to the national gross domestic product (GDP) of the country. Concerning construction processes, both risk management (RM) and value engineering (VE) techniques have commonalities from the beginning up to the completion of the project due to enhancing the project value/quality, meeting the project deadline, and reducing overall project cost. VE includes resolving the uncertainty of project objectives and ensuring that the project is delivered in a value for money way. The key point of RM is to solve the uncertainty of the project itself and its results to ensure that the specifications are achieved within the prescribed time, cost, and quality constraints. This review work is comparatively and collectively focused on assessing the role of RM and VE tools for project successful delivery. It studies the points of difference and common features of the two aspects in terms of construction project delivery. So, this study concluded that in construction RM tool cannot be the chief aim of the all parties involved in the project execution because sometimes it produces itself negative results and reduces project management success. Therefore, RM needs a strong combination with VE due to the dependence of the target in identifying and assessing risks by considering the highest performance and lowest cost. The integration of RM and VE combination in a single study would avoid duplication of work and deliver better value for money thereby leading to better project outcomes.

Theory and practice of value management and its innovation for natural resources from the perspective of sustainable development

The supreme obstacle for sustainable development of natural resources is the scarcity bottleneck. So how to promote the sustainable utilizing and increase the using efficiency of natural resources is worth studying. This pa-per suggests that we should improve the model and means of evaluating method and value management based on the theory of natural resource compensation. This paper discusses the User Cost Method based on the microeconomic aspect which can change the evaluating method for natural resources. From the perspective of value management model, we should use the User Cost Method to realize the linkage and integration of micro and macro compensation for natural resources. Based on the evaluating and accounting idea of User Cost Method, this paper presents a theo-retical framework to harmonize and link micro and macro compensation for natural resources. At present, we should seek the new approach and method to manage natural resources, so can we realize the capitalization management focusing on the value management for natural resources.

Research on Enterprise Value Chain Management Based on Competitive Strategy

With the rising cost of labor factors in China,several multinational companies that rely on labor-intensive industries have withdrawn their production lines from China,which has had a huge impact on the development of Chinese enterprises.Under the guidance of national policies,many enterprises have begun to climb to the high end of the value chain.This paper analyzes the main function of value chain management by studying the composition of industry value chain management from the perspective of competitive strategy.In view of the lack of enterprise value chain management,this paper discusses from three aspects:product,technology,and price.Product homogeneity has been found to greatly reduce the market competitiveness of products,which is not conducive to the value-added and sustainable development of enterprises.Based on this,corresponding strategies have been proposed,in which enterprises should maximize the advantages of value chain management through scientific and efficient information management techniques.

Development of a group support system to support collaborative works in value management workshops

Value Management (VM) is a rigorous and systematic approach to improve the value and optimise the overall cost of a facility. It identifies opportunities to remove unnecessary costs while assuring that quality, reliability, performance, and other critical factors will meet or exceed the customers’ expectations. It has been widely used in the construction industry in a number of countries. A recent survey, however, revealed several problems that hinder the wider use of this methodology in the industry. To overcome these problems, a feasibility study has been conducted to investigate whether or not a Group Support System (GSS) can support collaborative works in VM workshops. This paper introduces the development and structure of a prototype GSS which is designed to support the collaborative works of stakeholders in VM workshops. It begins with an introduction to the conceptual GSS framework and job plan, illustrating what GSS supports can be provided to VM workshops. This is followed by a detailed description of the GSS prototype system to demonstrate how these supports can be performed as an integrated computer system. The testing of the system is also discussed. The research findings provide strong evidence in supporting the notion of using GSS to improve VM implementation. The information support of GSS has been ranked to be the most useful GSS functions and most of the practitioners interviewed are highly interested in applying GSS to support VM workshops in the future.
