Two patents of Xi'an University of Electronic Science and Technology were approved by the Shaanxi Provincial Patent Award first prize in 2021

Recently, the Shaanxi Provincial Intellectual Property Office announced the 2021 Shaanxi Provincial Patent Award List, and the invention patent of Professor Ma Jianfeng and Professor Jiang Wen of Xi'an University of Electronic Science and Technology "the data access system and method of the encrypted database under the mixed cloud environment" "High -angle and stable frequency selection surface" won the first prize of the Shaanxi Patent Award.

Professor Ma Jianfeng's team invented the patent "data access system and method of the encryption database under the mixed cloud environment". Based on the efficient ciphertext operations of encrypted data indexes, the data integrity verification method proposed effectively guarantees the integrity of the data. Based on the "Qin Dun" cloud and crypto database system developed by this patent, a number of awards such as the National Technology Invention Award and the Shaanxi Provincial Science and Technology Award. A key model task planning system and other products such as the Chengdu Aircraft Design Research Institute of China Aviation Industry Corporation have cumulative sales profits of more than 60 million yuan, which has produced significant social benefits.

Professor Jiang Wen's team invented patent "a high -angle and stable frequency selection surface". For the problem of low surface angle stability of existing technology, the existing technology has a low -angle and stable 2.5D frequency selection surface selection surface. The unit structure reduces the unit size and reduces the offset of the resonant frequency during large angles of electromagnetic waves. It effectively improves the angle stability characteristics of the frequency selection surface. The patented technology has been successfully applied to a type of stealth aircraft high -level surface antenna developed by China Electric's 20, the electromagnetic environment dynamic test system developed by Shanghai Litian Communication Technology Co., Ltd., and the orientation control system developed by Jiangsu Kenli Technology Co., Ltd. The antenna and other products have supported the design of my country's future stealth aircraft. The patent output value has reached 76 million yuan, and the economic and social benefits generated are significant.

In recent years, the school has been supported by creating high -value intellectual property rights, with the purpose of promoting the use of intellectual property rights, and vigorously promoting innovation -driven development strategies and intellectual property strategies. , Explore the use of new models of innovation patents and strengthen the level of intellectual property information, etc., to comprehensively improve the quality of intellectual property creation, use efficiency, management level, and service capabilities. In the future, schools will continue to improve the mechanism of intellectual property creation, protection, and use, effectively integrate intellectual property work into the entire process of scientific and technological research and development and innovation of the school, strengthen high -value patent cultivation, further promote the transformation of patent results, and help the school's "double first -class" Construction, the high -quality development of local economy, has made greater contributions to promoting the construction of strong provinces of intellectual property rights.

It is reported that the Shaanxi Provincial Patent Award was established by the Shaanxi Provincial Intellectual Property Office to inspire the value and function of intellectual property rights in the province and promote the construction of intellectual property. There are no more than 2 participating projects. The main rewards have a positive role in promoting the patent owners and inventors who have achieved significant achievements in promoting innovation and promoting economic and social development, and have played a positive role in promoting high -quality development in Shaanxi Province. In 2021, the Shaanxi Provincial Patent Award Evaluation work has received widespread attention and active participation of all sectors of society. After organization review and publicity, a total of 25 first prizes, 34 second prizes, and 39 outstanding prizes.
