【摘要】：大數(shù)據(jù)時(shí)代的到來(lái),使得數(shù)據(jù)成為了重要的經(jīng)濟(jì)資產(chǎn).為了更好地利用它們,有償或無(wú)償?shù)墓蚕頂?shù)據(jù)將是一種趨勢(shì).作為確保大數(shù)據(jù)安全分享重要技術(shù)之一的訪問(wèn)控制技術(shù)也將在大數(shù)據(jù)時(shí)代發(fā)揮重要作用.該文首先對(duì)大數(shù)據(jù)及大數(shù)據(jù)應(yīng)用的新特點(diǎn)進(jìn)行分析,并提煉出這些新特點(diǎn)為訪問(wèn)控制領(lǐng)域帶來(lái)的五個(gè)迫切需要解決的新問(wèn)題:授權(quán)管理問(wèn)題、細(xì)粒度訪問(wèn)控制問(wèn)題、訪問(wèn)控制策略描述問(wèn)題、個(gè)人隱私保護(hù)問(wèn)題,以及訪問(wèn)控制在分布式架構(gòu)中的實(shí)施問(wèn)題.接著對(duì)相關(guān)訪問(wèn)控制關(guān)鍵技術(shù)的研究現(xiàn)狀進(jìn)行了梳理,包括角色訪問(wèn)控制、風(fēng)險(xiǎn)訪問(wèn)控制、半/非結(jié)構(gòu)化數(shù)據(jù)的訪問(wèn)控制、針對(duì)隱私保護(hù)的訪問(wèn)控制、世系數(shù)據(jù)相關(guān)的訪問(wèn)控制、基于密碼學(xué)的訪問(wèn)控制等.雖然這些現(xiàn)有技術(shù)不一定能直接應(yīng)用于大數(shù)據(jù)場(chǎng)景,但是它們都可以被大數(shù)據(jù)訪問(wèn)控制的研究所借鑒,以解決大數(shù)據(jù)帶來(lái)的上述訪問(wèn)控制的新問(wèn)題.在此基礎(chǔ)上,總結(jié)并提煉了若干大數(shù)據(jù)訪問(wèn)控制所呈現(xiàn)的新特點(diǎn):判定依據(jù)多元化、判定結(jié)果模糊化、多種訪問(wèn)控制技術(shù)融合化.最后,對(duì)未來(lái)大數(shù)據(jù)訪問(wèn)控制的研究進(jìn)行了展望,給出了一些有待研究的問(wèn)題.該文認(rèn)為大數(shù)據(jù)應(yīng)用的發(fā)展將為訪問(wèn)控制技術(shù)的研究提出許多新的挑戰(zhàn),同時(shí)也將帶來(lái)巨大的機(jī)遇,這必將引起訪問(wèn)控制技術(shù)的一次重大變革.
[Abstract]:The arrival of big data's era has made data an important economic asset. In order to make better use of them, It will be a trend to share data for free or paid. As one of the important technologies to ensure big data's safe sharing, access control technology will also play an important role in the era of big data. To analyze the new features of. Five new problems that need to be solved in the field of access control are abstracted from these new features: authorization management, fine-grained access control, access control policy description, personal privacy protection, etc. And the implementation of access control in distributed architecture. Then the research status of the key technologies of access control is reviewed, including role access control, risk access control, semi-/ unstructured data access control, Access control for privacy protection, access control related to descent data, access control based on cryptography, etc. Although these existing techniques may not be directly applicable to big data scenarios, But they can all be used for reference by big data's access control institute in order to solve the new problems of access control brought by big data. On this basis, This paper summarizes and abstracts some new features of big data's access control: the decision basis is diversified, the judgment result is fuzzy, and the multiple access control technologies are integrated. Finally, the future research on the access control of big data is prospected. This paper points out that the development of big data's application will bring many new challenges to the research of access control technology, and at the same time bring great opportunities, which will lead to a great change in access control technology.
