对日IT软件产业结构优化的研究

软件服务外包作为一个新型的软件产业方兴未艾,这种贸易方式加强了国际间的合作与区域性产业的互补。作为中国的近邻日本,这种互补方式的优势显得尤为突出。但是,由于中国外包企业的竞争力较弱、技术力量不够雄厚、企业规模尚未形成等弱点存在,大大制约着中国软件服务外包业的进一步发展。特别是随着诸多新兴接包国家和地区的崛起,使得中国所面临的竞争进一步加大,从前的低成本优势将得到削弱。这些都严重地制约着中国软件服务外包行业的健康发展。有序地调整以低端为主的产业结构,提高自主创新能力,加大服务外包在国家IT（Information Technology）产业中的比重,从而增强核心竞争力。     

Method for using the blockchain to protect data privacy of IoV

With the rapid development of the Internet of Things,vehicle industry is undergoing a rapid transformation from the early vehicle Ad-Hoc network to the Internet of Vehicles (IoV) in which massive vehicles and on-board smart devices can realize data sharing and interaction.However,this brings about a big challenge for the security of shared data in a huge volume containing a lot of user privacy,especially the issues of access control,trust and key escrow.To address these problems,we propose an efficient blockchain-based distributed data sharing method in IoV.In our scheme,blockchain transactions are utilized for trustworthily data storage and access as well as user revocation.To realize end device verification,we introduce certificateless cryptography for transaction verification of blockchain nodes and the ease of the key escrow problem.Moreover,we propose an efficient partial policy-hidden CP-ABE scheme for data fine-grained access control with efficient user revocation.Security analysis and experiments demonstrate that our scheme is secure,efficient and practical.     

Integration by communication: knowledge exchange in global outsourcing of product software development

Global outsourcing is a growing trend among independent software vendors. In these projects like other distributed work, distances have negative effects on communication and coordination, directly impacting performance. We present a normative model designed to address this issue by improving communication and knowledge exchange. The model consists of six distinct practices and a tool blueprint, each coming with practical guidelines. It is based in part on two case studies of Dutch software vendors who have successfully outsourced part of their activities to an Eastern European outsourcing vendor, and validated by a panel of six experts from industry and the scientific community. It is concluded that knowledge exchange in global software outsourcing is a by‐product of efforts to enhance communication and coordination, rather than specific technical solutions. By committing to sharing knowledge, emphasizing transparency and integrating the outsourcing team into their organizations, customers from the product software business can realize the benefits of global outsourcing.

Attribute-based encryption scheme supporting attribute revocation and decryption outsourcing

Aiming to tackle the attribute revocation issue and reduce the user's computational overheads, an attribute-based encryption scheme is proposed and it can support attribute revocation and decryption outsourcing. In the proposed scheme, the splitting and reconstruction of secrets is realized by the linear secret sharing technique, and key update is based on the KEK(Key Encrypting Key) tree. In decryption, our scheme outsources some decryption computational tasks to a decryption service provider, which reduces the computational cost on users' side. Security analysis indicates that the proposed scheme can resist collusion attack, and ensure data confidentiality and forward/backward secrecy. Experimental results show that the efficiency of ciphertext update and decryption is improved in terms of time cost.
