The standard model of cloud computing based on certificate hybrid encryption scheme ping Herdach with the rapid development of cloud computing, data security has become a key problem of cloud security, especially the large amount of data stored and transmitted in the cloud and the high security requirements. On the other hand, based on the certificate cryptosystem, it overcomes the problem of the traditional public key cryptosystem and the key escrow based on the identity cipher system, and provides a new method for constructing the security and efficient PKI, but the existing certificate-based encryption schemes mostly adopt bilinear pair structure, and the computational efficiency is low. For cloud computing environments, based on reduced judgment ...

"The rain that comes directly from the clouds is distilled water, and it is as safe as a tap that can be drunk," he said. Can you say the same thing about the data from the clouds? "How do you react when a water company sells as dirty as a typical spam message and a malware deluge of internet traffic?" said Dr Zhang Hongwen, the CEO of Czech network. This has become a key issue in the long-term survival of the internet! Water is the element of life: nearly 60% of our weight is made up of water. The existence of water is the first thing astronomers look for when they consider habitable planets. Find a good clean water, people ...

When the concept of cloud data storage appeared, people were really happy once. The advent of cloud data storage has allowed people to gasp in the fight against malware, keyboard sniffing, PC monitoring software, and so on. But when people move digitized baggage into the cloud, they forget the measures needed to ensure data security. Data protection in the cloud is not as difficult as protecting the security fence in the Android system, but sometimes it's not as easy as walking in a park. So in order to reduce doubt and help eliminate the fear of new technologies, this article lists 10 ways to make your life in the cloud fun ...

Research on differentiated security technology of cloud computing Li Dongmei Yin Shijun Chen Jianyong Cloud Deployment and application can significantly reduce cost to promote business innovation and development However, the public cloud has made the user data and business processing links to independent third parties to provide the security threat to the user data and business systems, which has become the main bottleneck of cloud computing development. In this paper, according to the security requirements for cloud business diversification, the differential security technology framework can reduce the consumption of cloud computing resources and promote the application of cloud computing under the precondition of satisfying the user's security requirements. Research on differentiated security technology of cloud computing

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, ...

As many manufacturers in the security industry slowly transform into managed security service providers, a specific application area has become the mainstream, namely, through cloud computing software, the vulnerability management of service delivery.
