Implementing information security mechanism over cloud network

Abstract

The security parts of distributed computing, particularly the security of information, turn out to be increasingly essential. It is important to build up another component to verify the information in the cloud. Cryptographic based symmetric key cryptosystems helps to provide an efficient way to protect information. Enhanced symmetric key cryptosystem AES algorithm has been proposed for securing the data and safely storing to the cloud. This paper is to provide an overall security to the files which are in the cloud so the encrypted file can be retrieved at any time from the cloud. The paper also aims to introduce the mechanism use to secure cloud computing applications as well as to compare some existing algorithm like RSA and AES with an enhanced AES algorithm and to prove that the proposed algorithm is more effective than the other two algorithms. The encryption speed of the algorithms is graphically represented in the paper.
