Abstract

Cloud computing is one of the leading phenomenal topic of nowadays. It raises the working nature of business. Cloud Computing is a very popular term in the field on computer science as the name describes, it completely means computation of data in a large environment. Anotherward, Security is one of the crucial and important factors in cloud computing environment. Here, possibility of improvement has been observed in dimension of security and enhanced authentication protocol has been explored. In this work we have developed a strong cloud environment using Kerberos authentication protocol. The problem and algorithm proposed is based on security of data in cloud environment. Where, modified algorithm of Kerberos is used. Along with it RSA and ECC is also used this approach is used for encryption and decryption. Kerberos algorithm is applied when client wants to access the data.

Introduction

Cloud computing is widely used in many organizations and also adapted to access different services provided by cloud. It has a capability of storing, sharing, accessing, processing and networking. Customers can use cloud to deploy, develop, execute and run their software with providing necessary resources as required. This environment of cloud computing creates storing and sharing of resources whose extension cannot be defined.

Conclusion

The complete observation concludes that the environment is created for storing, in secure manner. In the complete work we have discussed about security which can be implemented using Kerberos protocol along with RSA and ECC algorithm. Many researches and study is done which describes that data loss and dependency on cloud vendors creates the loss of control on data loss. This approach of security using Kerberos authentication protocol is the better way and with the Kerberos protocol, RSA and ECC is also used, which will make it more secure. RSA and ECC here used for encryption and decryption using public key and private key. The complete work observes that the algorithm used are beneficial and through it, it can be concluded that on the basis of need of cloud, better security is implemented.
