Data Attribute

Foreword PVE, the English full name is the player versus Environnement, generally all directly translates "The player to resist the environment".　　This term refers to a player who takes risks in the context of a game designer, such as making a copy, accomplishing a task, and taking down a boss, etc. in other words, PVE means that the player must defeat the NPC created by the game designer, rather than the role manipulated by other players. PVE is the main activity of most players in World of Warcraft, this article is about PVE design, including equipment ...

Study on data access control strategy of meteorological cloud based on attribute encryption Fangzhong Xiazhihua Zhou Shu with the increasing of meteorological service level, the problem of cloud storage and instant sharing of meteorological data is becoming more and more prominent. Aiming at the problem of identity authentication and access control for meteorological data storage and sharing in cloud computing environment, an access control model of attribute encryption based on multiple authorization is proposed. This model adopts a kind of attribute encryption scheme which is suitable for large data in cloud environment, solves the problem of fine-grained access control of data in meteorological department, and introduces the concept of global ID and multiple authorization mechanism to solve ...

Research on attribute-based user rights Management in cloud environment Li Yubao Fannai Kihuimin Liu Yan User Rights Assignment is one of the most important problems of cloud computing service, and proposes a user Rights management scheme based on attribute. This scheme takes the new user key distribution in cloud service as the research object, in this paper, the user signature authentication and decryption management mechanism is discussed, and the data owner and the authorized person choose the attribute set, and the data owner defines the ciphertext access structure based on the attribute set, so that the user can obtain the decryption key only through the authorized person authentication. Achieve the goal of user privilege escalation and degraded synchronization management. Another ...

Research and realization of access control subsystem based on attribute encryption in cloud storage Sun Youpeng because of the complexity of the cloud environment, the various entities are not trusted, so password access control technology to prevent user data leakage is the most direct means. In recent years, the academia has introduced the attribute-based encryption system in the access control, which is a method developed on the basis of identity encryption. This paper chooses the access control technology in cloud storage as the research direction, and deeply analyzes some problems of access control technology based on attribute encryption. Including the lack of access policy expression, permission to withdraw ...

In this paper, a cryptographic scheme for cloud storage is Liu, in which there is a lack of fine-grained access control, difficulty in key management, and difficult to resist collusion attack in the application environment of Yang Mingyun storage, a new ciphertext policy attribute base encryption for cloud storage is proposed (Ciphertext-policy attribute-based encryption, Cp-abe) program. By introducing the license attribute of the main independent control of the data, constructing the Cp-abe scheme of the different attribute domains can prevent the cloud storage system ...

Research on cloud computing security based on attribute encryption University Guo Lijun This paper analyzes the security problems existing in the Hadoop architecture and file sharing system, and puts forward the corresponding solutions with the attribute encryption algorithm. First of all, for the security problem of Hadoop architecture in cloud computing environment, this paper designs a complete set of solutions to solve the security problem with Cce-abe algorithm, and introduces the main idea, security hypothesis and the whole process of the security Hadoop architecture. Finally through the user to use K clothing ...

A Revocable property encryption scheme for cloud storage penning Zhu Zhiqiang Nate Zhihuian Because of the large number of cloud storage users and complex components, the security protection of data in cloud storage has become a major constraint, in recent years, based on attribute encryption technology to solve the problem of data security storage in cloud storage becomes a research hotspot, However, traditional attribute encryption schemes have some problems, such as relatively large cipher length and complex attribute cancellation. By introducing proxy encryption technology, a revocable ciphertext attribute base encryption scheme is proposed for the above problems, and the attribute cancellation is realized while shortening the cipher length.

In recent years, with the emergence of new forms of information, represented by social networking sites, location-based services, and the rapid development of cloud computing, mobile and IoT technologies, ubiquitous mobile, wireless sensors and other devices are generating data at all times, Hundreds of millions of users of Internet services are always generating data interaction, the big Data era has come. In the present, large data is hot, whether it is business or individuals are talking about or engaged in large data-related topics and business, we create large data is also surrounded by the big data age. Although the market prospect of big data makes people ...
