Enhanced Security using Hybrid Encryption Algorithm

Neha, Mandeep Kaur

Information Security plays a major role in today’s scenario. Cloud computing is a technology that provides access to information and computing resources from anywhere that a network is available. There is a need to secure the data stored on cloud. The main goal behind the design of encryption algorithm must be security against unauthorized attacks. However, for all cloud computing applications, performance and cost of implementation are also major concerns. Encryption algorithm would not be of much use if it is very much secure but slow in performance. The security and performance of encryption algorithms must be balanced. In this paper, encryption algorithms (AES, Blowfish, Twofish) has been discussed to analyze the performance level of each algorithm.
