Multilayered Security Approach for Cloud Data Centers using Hash Functions

Jashanpreet Pal Kaur | Rajbhupinder Kaur

Abstract: Cloud Computing provides computing over the internet. The cloud is not a trust worthy because there is no control of users on the data. Hence, the cloud data centers are vulnerable to assorted attacks. It is required for the cloud service providers to ensure the secured data transmission in the cloud framework. There is also dependency among the layers. So attack at any layer may affect the other layers. This paper proposed a new multilayered security approach means the security at different levels of different cloud layers to secure the data stored at cloud data centers based on dynamic hybrid key then performance of proposed algorithm is evaluated at last based on execution time, security improvement percentage and delay.

Keywords: Security Issues in Cloud computing, Cryptography, MD5 and SHA1 Algorithms, Static and Dynamic Keys
