In the year of 2012, the institute won the First Prize of Science and Technology Progress Award of Ministry of Education. Its major in-development projects are “Scalable Theory and Key Technology of Low-Energy Large Data Centers” (key project of NSFC), “E-Commerce Oriented Network Operating System” (key project of China Cloud Computing Phase I), one project supported by the Special Funds for the Development of Strategic Emerging Industries, E2S2 project (Energy and Environmental Sustainability Solutions for Megacities) of CREATE (Campus for Research Excellence And Technological Enterprise), one key project of the Ministry of Education, etc. During the past three years, the institute has presided over 10 scientific research projects and obtained funds of more than 40 million yuan.
“Shanghai Cloud Computing Joint Lab”, a project supported by the Special Funds for the Development of Strategic Emerging Industries, belongs to the “Cloud Computing Service Development Pilot Demonstration Projects” initiated by the National Development and Reform Commission, the Ministry of Finance and the Ministry of Industry and Information Technology. The project is directed by the state and Shanghai’s strategic goal of information industry development and the Shanghai’s strategy of developing the municipality through science and education as well. Through the integration of industry, university, research institute and market, it aims to conduct researches on the core generic technology of cloud computing, yield original innovative results and independent intellectual property rights and form a high-level research team, so as to enhance the innovation ability and core competitiveness of Shanghai in cloud computing and provide strong scientific and technical support. A research team mainly comprised by members of the institute was selected as the innovative team of the Ministry of Education in 2011.
E2S2 is a key Sino-Singapore cooperation project (CREATE). Including four subjects, it was approved in 2011 by National Research Foundation SINGAPORE and granted a funding of 300 million yuan. The Institute of Parallel and Distributed Computing presides over the second subject “Distributed Clouds Peta-scale Urban Sensing and Data Management”, the aim of which is to develop advanced computing technologies such as cloud computing and big data processing and analysis and eventually to provide information support to the sustainable development of super large-sized cities. It is a landmark project of the substantive research cooperation between SJTU and world-class universities and a breakthrough regarding the amount of overseas funding obtained by research teams of SJTU.

Algorithmic Mechanism Design for Dynamic Spectrum Redistribution
With the fast deployment of wireless communication technologies, radio spectrum is becoming a more and more scarce resource. For historical reasons, much of the radio spectrum is statically allocated. The inefficiency of such an allocation is twofold. On one hand, the static allocation does not consider spatial and temporal variations of the spectrum. Large chunks of radio spectrum are left idle most of the time at a lot of places. On the other hand, many new wireless applications cannot find enough radio spectrum to operate on. Therefore, redistribution of idle radio spectrum is important to make a better utilization of the limited radio spectrum.
We investigate the problem of dynamic radio spectrum redistribution in a framework of algorithmic mechanism design, and have proposed a series of approaches to tackle the challenges in the dynamic spectrum auction, including strategy-proofness, spatial reusability, channel heterogeneity, demand diversity, computational intractability, collusion resistance, privacy preservation, and correctness verification. Related research outcomes have been published in various international conferences and journals, such as IEEE INFOCOM, ACM MobiHoc, IEEE Transactions on Mobile Computing, IEEE Transactions on Computers, and IEEE Transactions on Parallel and Distributed Systems.
Secure Nearest Neighbor Query
Cloud computing has become more and more popular due to its flexibility and scalability. One of its applications is that cloud computing service providers provide access to cloud databases. Data owners outsource their databases to cloud service providers and rely on them to provide services such as database storage, management and query. However, the remote placement of data poses security threats. Data owners expect to prevent the leaking of data and query information while using cloud services. We have studied how to process data querying in the context of outsourcing without leaking information (including data and query information), which focuses on the nearest neighbor problem. We first pointed out the security vulnerabilities of the existing methods, proving that the secure nearest neighbor problem is of the same difficulty with order-preserving encryption problem. Since order-preserving encryption is proven to be very difficult to build under the standard security model, we propose a new solution. By partitioning, filling, and encrypting data block, users can find the nearest neighbor by simply obtaining one piece of encrypted data. This ensures security and also improves query efficiency. The results were published at IEEE ICDE 2013.
