Encryption Techniques

Securing data is a challenging issue in the present time. Data security refers to protective digital privacy measures that are applied to prevent unauthorized access to the important information. Cryptography protects users by providing functionality for the encryption of data and authentication of other users. Data compression is the art of reducing the number of bits needed to store or transmit data.

Cloud computing provides many benefits to the users such as accessibility and availability. As the data is available over the cloud, it can be accessed by different users. There may be sensitive data of organization. This is the one issue to provide access to authenticated users only. But the data can be accessed by the owner of the cloud. So to avoid getting data being accessed by the cloud owner, we will use the intrusion detection system to provide security to the data. The other issue is to save the data backup in other cloud in encrypted form so that load balancing can be done. This will help the user with data availability in case of failure of one cloud.

Cloud computing has good services like virtualization. Virtualization provides the unlimited computational resources. Cloud computing provides robust design with low cost. Different security constraints are satisfied in outsourcing with the implementation of new encryption standards. These above services give the reliable solution in secure transmission. Previous systems cloud environment enables the computational resources are limited whenever access the resources in outsourcing. These resources utilization are pay per use manner here. Previous servers have processing storage, memory levels are less. There is no possibility for encryption complete content. Some content available as a plain text, remaining content available as a cipher text. This two type’s format content starts the transmission. Attackers are entering automatically leakage of data problems generate here. That’s why this type of network comes under insecure. It can deliver the incorrect data in destination. Users are not satisfies with the help of these services. Security is the primary obstacle that prevents the wide adoption of this promising computing model, especially for customers when their confidential data are consumed and produced during the computation. The above limitations are overcome using the linear programming in cloud computing. These types of techniques are providing good secure network and optimization solution. User is ready for transfer the large file to another user. Here large file assume as a large problem. Using linear programming large files divide into sub parts using decomposition. Transformation techniques start the allocation of decomposed parts in different servers. Different servers provide the perfect infrastructure for encryption with sufficient computational resources. Before starts the outsourcing total content is encrypted in client side. After deliver the content verifies the proof. Proof it is matched with server proof then performs the decryption. It’s delivers as a correct data.
