Comparative Study Between Cryptographic and Hybrid Techniques for Implementation of Security in Cloud Computing

Cloud computing depicts the latest technology in the field of information communication technology. Cloud computing technology offers the user with an endless list of services which they can avail, and these services range from hardware and software and infrastructure to resource utilization. Cloud computing allows us to access online software application, data storage, and processing power of system from anywhere and at anytime. Cloud computing supports the organization to increase their capacity remotely without creating own infrastructure, platform, purchasing new licensed software that is required for automation of various processes. There are a number of dominant parameters like energy dissipation, resource allocation, virtualization, and security that a user needs to keep in mind while selecting cloud computing services. Of the dominant parameters, security as a parameter in cloud holds a special concern and is one of the biggest challenges in cloud computing as far as data transfer process and data storage process are a concern as it happens through the Internet. In this research work, the authors have presented a comparative study between cryptographic and hybrid techniques for security concerns of the cloud computing paradigm. Through the results obtained from the comparative study of these techniques, it is observed that the effectiveness of the hybrid techniques is better in terms of execution of the algorithm than the cryptographic techniques (common public- and private-key cryptography) of security implementation in cloud computing.
