TO ENHANCE MULTIMEDIA SECURITY IN CLOUD COMPUTING ENVIRONMENT USING CROSSBREED ALGORITHM
Sonal Guleria, Sonia Vatta · 2013
Cloud computing is emerging field because of its performance, high availability, least cost and many others. In cloud computing, the data will be stored in storage provided by service providers. But still many business companies are not willing to adopt cloud computing technology due to lack of proper security control policy and weakness in safeguard which lead to many vulnerability in cloud computing. This paper has been written to focus on the problem of data security. Service providers must have a viable way to protect their clients’ data, especially to prevent the data from disclosure by unauthorized insiders. To ensure the security of users’ data in the cloud, we propose an effective and flexible scheme with two different algorithms .A user can access cloud services as a utility service and begin to use them almost instantly. These features that make cloud computing so flexible with the fact that services are accessible anywhere any time lead to several potential risks. The key intent of this research work is to investigate the existing security schemes andto ensure data confidentiality, integrity and authentication. In model RSA algorithm and DES algorithm cryptographic algorithms are adopted for the optimization of data security in cloud computing. These days encryption techniques which use large keys is seldom used for data encryption due to computational overhead. Their usage is restricted to transport of keys for symmetric key encryption and in signature schemes where data size is generally small. In the first section of the paper analysis the cloud computing Techniques and fundamental concept of multimedia cloud computing. In the second section of the paper analysis the related work of security terms of cloud computing. In the third section are discussed about proposed work of Security method of RSA and DES. In the fourth section described characteristics of multimedia cloud computing and in the fifth section analysis the RSA Algorithm & DES Algorithm. Finally present the Conclusion & future works with the references.
