“Cloud computing” provides the brand-new calculation mode for data analysis processing in the current IT field. In other words, the cloud-end data calculation system constituted by lots of server groups can replace the single operation system with the center of personal computers. In order to further discuss the network safety under the “cloud computing” environment, the effective network safety strategy was proposed. 1.Introduction With the innovation and development of internet technology in today’s society, the scale of network application is gradually expanding. The data processing demands are gradually improving. As the brand-new computing network technology, the cloud computing technology emerged at the right moment. After entering into the cloud computing and cloud storage era, enterprise-level system calculation work starts using distributed storage and deployment mode to complete it. The data security problem of the cloud computing technology is the barrier to obstruct the further promotion and utilization. The security of the cloud data determines the trust degree of users, while the trust degree of users determines the development space of the cloud storage. It is necessary to analyze the key technology in the current cloud computing field and strive for more reliable space for cloud storage. 2. The Data safety strategy analysis under the cloud computing environment. A. The overall operation performance of the cloud computing. Two groups of the same data buffer memories are allocated for all physical calculation equipment of the entire cloud computing system. Here, they are named as the CacheA memory and CacheB memory. Then, they are conducted the initial treatment. Each memory is divided for caching. It can be observed from Figure 1 that two groups of memories have users with the same color. When users need to do data calculation and storage, CacheA and CacheB will enter into the normal working state. Under the circumstance, in order to complete initial treatment for Cache memory, it must conduct the timing operation. Once timing is about to reach the established period, it is necessary to select Cache memory to complete the Cache rotation procedure of a period. 73 2017 8th International Computer Systems and Education Management Conference (ICSEMC 2017) Copyright © (2017) Francis Academic Press, UK Fig.1 Cache Regional Distribution The hardware resource division strategy of mutual exchange in the Cache region will make users share Cache region and reduce waste of hardware resources, so as to accelerate the overall operation performance of cloud computing. B. The Safety Strategy of the Reliable Cloud Model Based on the Cloud Computing Environment With the popularity of the cloud computing application, an increasing number of users select hardware and software resources that they can apply and also upload their resources to the cloud for other users to download. Meanwhile, users also worry about cloud resource safety. In addition, the hostile attack and stealing of some crackers also make the trust problem between users and CSP become difficult to be solved. X is set up as a union of credibility, X={x}, called as the space of credibility {one-dimensional, two-dimensional or multi-dimensional}. The subjective qualitative trust for the space of credibility X means that any element x has a random number with the stable tendency, y=UA(x), called as the x’s credibility for A. The distribution of credibility on X is called as the trusted cloud. The proposal of TCCP model opens a new idea to solve such a problem. The cloud computing is combined with the trusted calculation to solve such a problem in the technical level. TCCP model is closely linked with the trusted calculation platform. Throughout numerous safety issues faced by the cloud computing, security of user data and privacy is extremely important. In order to cope with such a safety problem, CSP conducts the encryption processing on internal messages of the cloud. As a result, users are short of the right to know about the uploaded resources. In addition, after users upload their data resources, they lose the control right to these resources. In this way, there is short of information between users and CSP. This obstructs cloud computing development to a large extent. In the three models of cloud computing(IaaS, PaaS, SaaS), only IaaS is transparent to users. In addition, users also have certain control permission. IaaS model is easier to solve a safety problem. The original TCCP model is designed based on such a principle. The management cloud service is used to prevent illegal invaders from tampering the trusted nodes(TNs) in the inner cloud or it will manage TNs as a coordinator. The specific model figure is shown in Figure 2. Fig.2 TCCP Model Figure
