面向移动云存储的属性基解密服务中间件

属性基加密（ABE）算法支持对云端数据的细粒度访问控制。针对属性基解密计算复杂度高,难以在资源受限的移动终端上实现的问题,提出并实现了一种面向移动云存储的属性基解密服务中间件。在保证密文信息不被中间件获取的前提下,中间件为移动终端代理属性基解密服务,实现了基于树形结构的线性秘密共享（LSSS）矩阵求解,降低了终端的计算与通信开销,提高了解密速度;属性权威可以在不需要用户参与的条件下,即时、细粒度地撤销用户属性;所有接口均使用Restful服务,保证了通用性。实验结果表明,属性基解密服务中间件提高移动设备解密性能近30倍,具备较好的并发性能,属性撤销具有实用性。

Contextualisation of the complexity in the selection of developing country outsourcees by developed country outsourcers

Outsourcing research has recognised that selecting the right offshore supplier (outsourcee) in low-cost distant developing countries is complex, but central to outsourcing success. More specifically, the combination of outsourcee contextual internal factors (e.g. capabilities) with outsourced-to country contextual external factors (e.g. political, legal, economic, socio-cultural) as two fundamental and interconnected decisions firms make when outsourcing remains an underexplored research gap. Therefore, through a rigorous three-tier qualitative approach we, firstly, develop a contextual Environmental Separation Index (ESI) decision tool to help outsourcing firms in making more informed decisions when selecting outsourcees and outsourcing locations. Secondly, we operationalise the ESI as intuitive and easy to use decision tool, yet with a provision to deliver a truly context proof outsourcee selection decision. Thirdly, we adopt a complexity theory lens to explain that narrowing the contextual outsourcer–outsourcee gap facilitates a mind-set shift in outsourcing relationships from hierarchies to networks and from controlling to empowering developing country outsourcees. We show from a complexity theory perspective how contextual separation gaps between developed country outsourcers and developing country outsourcees can be an effective way to grasp the evolutionary path of outsourcing relationships.     

Should competing original equipment manufacturers outsource procurement activities under asymmetric cost information?

This paper considers a supply chain in which two competing heterogeneous original equipment manufacturers (OEMs) outsource production to a common contract manufacturer (CM) that possesses private cost information. Along with production outsourcing, the OEMs can either purchase components by themselves and only assign the production tasks to the CM (Consignment), or delegate both the procurement and production tasks to the CM (Turnkey). The main question we address is whether the OEMs should adopt Consignment or Turnkey. To answer this question, we first analyse the OEMs’ optimal mechanism design problems under three scenarios: both OEMs adopt Consignment strategy; both OEMs adopt Turnkey strategy; one OEM adopts Consignment and the other one adopts Turnkey. Building upon the OEMs’ equilibrium decisions under each scenario, we then characterise the equilibrium outcome for the procurement game. The results show that the CM’s procurement cost distribution and the market size play critical roles in the equilibrium outcome. Additionally, we find that both the competition intensity and cost heterogeneity between the OEMs affect the equilibrium outcome.     

A bi-level constraint-oriented outsourcing framework for orchestration of an ERP system

Outputs of each enterprise resource planning (ERP) process in an ERP system could constraint outputs of the next ERP processes. Therefore, it is necessary to determine the ability of ERP processes to support the orchestration of an ERP system. This paper presents a bi-level constraint-oriented outsourcing framework to identify any ERP process that effects on the orchestration of an ERP system. The contribution of the proposed bi-level constraint-oriented outsourcing framework for orchestration of ERP is twofold: (1) it develops the traditional constraints management from a crisp single-criteria environment to a fuzzy multi-criteria environment; and (2) it develops a linear programming technique for multidimensional analysis of preference (LINMAP) model to a fuzzy group bi-level LINMAP model. A case study demonstrates the applicability of the proposed constraint-oriented outsourcing framework for orchestration of ERP modules and processes.
