区块链支撑农业大数据安全初探

Preliminary Exploration of Big Data Security Supported by Blockchain in Agriculture

大数据是智慧农业的核心,但大数据安全还存在或面临很多问题和挑战,如果得不到解决,必然制约其稳健发展,甚至导致根基不稳。近年来随着区块链技术不断发展,以及其与生俱来的安全特质,为大数据发展注入了强劲的驱动力,拓展了新的应用空间。本文围绕区块链如何支撑大数据安全发展的有关问题,简明阐述了中国农业现状及智慧农业发展的背景;结合智慧农业数据需求问题,分析研究了大数据安全、区块链二者的相互关系,包括大数据安全的重大意义、存在的安全风险、一些挑战性难题、以及应采取的相应对策等;综合分析了区块链的安全特质,阐述了区块链在大数据安全中的支撑地位和作用,以及区块链在数据安全研究的三个核心方向,即数据的机密性、完整性、可用性;提出了如何应用区块链助力大数据安全发展的一些建议,并对应前景进行了简要展望。

Big data constitutes a core technology for smart agriculture.However,there are a number of issues related to security with big data that could limit progress with smart agriculture.Following the speedy development of blockchain technology and in light of its intrinsic security characteristics.Big data could provide a new driving force and means for big data to be safely applied.This paper addresses some challenges related to supporting the safe development of big data.Briefly described the current status of China’s agriculture and the background of the development of smart agriculture.Regarding basic issues concerning smart agriculture,a systematic study is made of the mutual relationship between agricultural big data security and blockchain technology which involves a brief introduction to the significance of big data,existing risks of big data,current challenges,and measures to promote bigdata safety.Comprehensive analyzed the security characteristics of the blockchain,described the supporting status and roles of blockchain in big data security,and explained three core directions of blockchain data security,which are data confidentiality,integrality,and availability.In conclusion,proposed suggestions and future applications on how to use blockchain to help the security of big data development.
