Abstract

Cloud Computing is one of the most famous field in the world of computer science research. The layered architecture forms a pyramid with categorization SaaS, PaaS&IaaS laid top to bottom. The user of this service model goes pay-per-use basis to the service provider. Like the other popular field, cloud computing too attracts those who likes to find loopholes to benefit themselves illegally. In this paper, we are using Kerberos at the server end, to avoid third-party dependency. To achieve confidentiality, cryptography is also taken in use along with the elliptic curve.

Introduction

Cloud computing is been known and applied on a huge scale in any business organization. The ease of access to the services is the primary reason behind the popularity of cloud computing. In this model, software, platform, and even entire infrastructure is capable of getting delivered to all possible ends. Cloud computing bags all the leading organizations as it’s investor & they provide the ease of access on payper-use basis. To expand business and gain popularity, some new cloud vendors are providing free services too. Windows Azure, Google Drive, Apache Hadoop are some famous examples of cloud vendors. Cloud computing is both efficient & scalable service, it lowers down the memory requirement & computation time too. With all the ease of access and enabling users to enjoy services from all possible ends of the world, Cloud computing surely lacks when it comes to security. Processing cost and computation is compromised while providing the required security, hence most of the time security stays as a compromised entity. Encryption is used in security but that is just a part of it and never fulfil the requirement. Security feature is claimed to be provided by all the leading cloud vendors. To achieve a user compatible atmosphere, security is a must factor.

Conclusion

As we are well-known to the fact already that security is the basic need of the cloud system. The work discusses here the application of Kerberos which provides seamless security. Merging ticket granting approach with Kerberos can achieve desired security. Kerberos security in cloud-based architecture is suggested in our work paper. Calculation of computation time & other factors including implementation of the given solution can be a given in the future work on this paper.
