Beyond that, industry integration between the Internet and other fields, such as finance, retail and advertising, is also eye-taking, as it has fostered a novel industry chain structure and business model. With an aim to realize the transformation and upgrading of conventional industry, the Chinese government has proposed ‘Internet plus' to encourage the combination of the Internet and conventional sectors. As one of the most important and complex conventional industries, the oil and gas(O&G in abbreviation) industry is also seeking the opportunity to actively cooperate with the Internet. However, after analysis of the differences between the particularities of the O&G and Internet industry from an economics perspective, a comprehensive combination of these two seems less promising, but adopting Internet related technologies to improve the performance of the O&G industry is feasible.展开更多

Many schemes have been proposed to support the keyword search in a public cloud. However,they have some potential limitations. First,most of the existing schemes only consider the scenario with the single data owner. Second,they need secure channels to guarantee the secure transmission of secret keys from the data owner to data users. Third,in some schemes,the data owner should be online to help data users when data users intend to perform the search,which is inconvenient.In this paper,we propose a novel searchable scheme which supports the multi-owner keyword search without secure channels. More than that,our scheme is a non-interactive solution,in which all the users only need to communicate with the cloud server. Furthermore,the analysis proves that our scheme can guarantee the security even without secure channels. Unlike most existing public key encryption based searchable schemes,we evaluate the performance of our scheme,which shows that our scheme is practical.展开更多
