Anonymous chaotic cloud storage strategy based on Cp_abe and two-fork tree partial codes Hebei University Yi Qingqing with the application and development of cloud computing technology, cloud storage and its security, as its basic component, have become the focus of the research. Cloud storage is a new concept that extends and develops in the concept of cloud computing (cloud computing), which means that a large number of different types of storage devices in the network can be assembled together through application software through the functions of cluster application, grid technology or Distributed File system, Together to provide data storage and business access function ...

Essentially, all cloud computing services consist of a "stack", this may include hardware assets (server memory, CPU, disk), virtualization technologies running on hardware, network formation (including physical and virtual), additional computing and programming software, mass storage and virtual machines (VMS), or application and software instances. While this broad set of technologies opens up a world of opportunity in computing, companies must know that vulnerabilities can occur in the cloud stack because of the way in which these technologies interact and the features that are often shared among cloud computing customers. For example, in multi-user systems, ...

For enterprises, deploying cloud technologies faces many challenges, not only to protect data residing in the cloud or through the cloud, to avoid sensitive data leaks, but also to protect departments, remote offices and mobile workers from cyber criminals, and more and more cyber criminals are starting to take advantage of emerging technologies such as the cloud, such as 　　 　　, mobile apps and cloud APIs) to spread malware and launch targeted attacks. Phil Hochmuth of IDC, said: "Body ...

In the rapid development of the Internet industry today, the continuous updating of network technology has made the traditional way of social production has undergone tremendous changes. But the internet brings convenience to people's production and life at the same time, also brings great security hidden danger. To protect the enterprise's increasingly large information data, the current approach is the firewall, anti-virus software, intrusion detection and other traditional security equipment. Admittedly, these commonly used security devices can defend against some of the conventional attacks, but at the same time we have to accept a brutal reality, many enterprises in the deployment of almost all traditional security ...

"Hollywood photo door" More than 100 injured stars, Apple 3rd issued a statement that the "pornographic door" incident and Apple icloud of the program loopholes or the iphone's specific features have nothing to do. Apple has mobilized all available engineers and technicians to investigate. 　　Still, the security of cloud computing is once again the focus of public opinion. The "New York Times" 3rd, said the current cloud computing information "Access control Communications card" has many loopholes. For internet companies such as Apple, it is hard to find a good balance between the security and convenience of information. US Bloomberg ...

Research and implementation of cloud computing security technology based on HDFs the Guo San Changbenwen innovation of Guangdong University of Technology is as follows: (1) based on the principle of Ibe algorithm, the Datanode authentication security mechanism of client access under HDFs is designed, In order to make up the original HDFS architecture under the client Access Datanode has not been certified defects, so that malicious or counterfeit users can not go through the main server Namenode to steal the private data on the Datanode to ensure data security. At the same time, using the principle of class Ibe algorithm,...

Jackie Gilbert, co-founder and vice president of Sailpoint, said it was in trouble when an institution purchased a 6th or 8th SaaS application. We will see auditors pay more attention to this issue and more security issues related to this issue. Sailpoint sells software that enables these applications to comply with corporate policies. Gilbert says the IT department is discovering that if the department that buys these applications processes software settings or does not set them up, they cannot manage or control access to SALESFORC ...

Research on the security model of cloud computing based on trust Shandong Normal University Zhang Yandong Cloud Security is always a cloud service provider cannot but face the soft rib, it and cloud computing development foreground is closely related. It can be said that, out of the security, cloud computing applications and promotion is not possible to talk about. Although the traditional security solution solves the security problem in cloud computing to some extent, it is absolutely not available to transplant this package to the cloud platform completely. New features such as the high level of virtualization of cloud computing, the complexity of deployment, and high scalability have prompted us to study the security mechanisms that apply to cloud computing. Where the trust problem is the cloud ...
