【摘要】：隨著移動(dòng)互聯(lián)網(wǎng)技術(shù)的發(fā)展，數(shù)字作品作為一種文化的載體越來(lái)越廣泛的被人們所使用，數(shù)字作品交易的規(guī)模也越來(lái)越大。而在現(xiàn)有的數(shù)字作品交易過(guò)程中不存在可信第三方，，交易中沒(méi)有數(shù)據(jù)對(duì)沖的過(guò)程，內(nèi)容提供商無(wú)法確切地知道數(shù)字作品的實(shí)際銷售情況，無(wú)法保證交易數(shù)據(jù)不被篡改。因此，亟需研究出可信的數(shù)字作品交易模式以及與之相對(duì)應(yīng)的交易數(shù)據(jù)訪問(wèn)控制機(jī)制，從而保證數(shù)字作品交易過(guò)程的可信與可控。 本文研究了訪問(wèn)控制技術(shù)的發(fā)展趨勢(shì)，比較并分析了多種訪問(wèn)控制模型在角色、環(huán)境狀態(tài)、時(shí)間狀態(tài)方面的特性。針對(duì)現(xiàn)有數(shù)字作品交易流程中的缺陷，以版權(quán)保護(hù)可信交易數(shù)據(jù)管理平臺(tái)為中心分析了可信數(shù)字作品交易的訪問(wèn)控制場(chǎng)景及需求。 以ABAC模型為基礎(chǔ)，提出了數(shù)字作品交易過(guò)程的管理方案，根據(jù)基于ABAC的協(xié)作信息系統(tǒng)訪問(wèn)控制安全結(jié)構(gòu)體系設(shè)計(jì)了數(shù)字作品交易數(shù)據(jù)管理平臺(tái)訪問(wèn)控制機(jī)制。對(duì)提出的訪問(wèn)控制機(jī)制中的網(wǎng)絡(luò)位置信息、軟件信息的獲取方案進(jìn)行了介紹，同時(shí)描述了數(shù)字作品交易數(shù)據(jù)管理平臺(tái)訪問(wèn)控制安全體系結(jié)構(gòu)中的安全關(guān)聯(lián)內(nèi)容�；谛袨榈燃�(jí)的概念，對(duì)服務(wù)器在獲取用戶的角色信息、環(huán)境及時(shí)態(tài)狀態(tài)后對(duì)用戶操作權(quán)限進(jìn)行分配的內(nèi)容進(jìn)行介紹，并將該權(quán)限分配方案應(yīng)用于數(shù)字作品交易數(shù)據(jù)管理平臺(tái)。 本文提出的訪問(wèn)控制機(jī)制可廣泛應(yīng)用于數(shù)字出版、電子商務(wù)等電子交易領(lǐng)域，并且支持移動(dòng)計(jì)算的遠(yuǎn)程訪問(wèn)、跨域協(xié)同訪問(wèn)以及信息資源多安全級(jí)的訪問(wèn),具有廣泛的普適性。
[Abstract]:With the development of mobile Internet technology, digital works, as a carrier of culture, are more and more widely used by people, and the scale of digital works trading is becoming larger and larger. However, there is no trusted third party in the existing digital work trading process, and there is no data hedging process in the transaction. The content provider can not know the actual sales situation of the digital work, and can not guarantee that the transaction data will not be tampered with. Therefore, there is an urgent need to study the trusted digital work trading model and the corresponding transaction data access control mechanism, so as to ensure the credibility and controllability of the digital work trading process. In this paper, the development trend of access control technology is studied, and the characteristics of various access control models in roles, environment states and time states are compared and analyzed. Aiming at the defects in the current digital work trading process, the paper analyzes the access control scenarios and requirements of trusted digital works trading based on the copyright protection trusted transaction data management platform. Based on the ABAC model, the management scheme of digital work transaction process is proposed, and the access control mechanism of digital work transaction data management platform is designed according to the access control security architecture of collaborative information system based on ABAC. This paper introduces the network location information and the software information acquisition scheme in the access control mechanism, and describes the security association content in the access control security architecture of the digital work transaction data management platform. Based on the concept of behavior hierarchy, this paper introduces the content of user operation rights allocation after the server acquires the user's role information, environment and temporal state, and applies this scheme to the digital work transaction data management platform. The access control mechanism proposed in this paper can be widely used in electronic transactions such as digital publishing, electronic commerce and so on. It also supports remote access to mobile computing, cross-domain cooperative access and multi-security access to information resources.
