IMPLEMENTATION OF HYBRID AES AND TWOFISH FOR CLOUD SECURITY

Abstract

Now a days, Cloud Computing is an emerging technology that enables users to use their
services from anywhere in the world. It has been widely adopted by many organizations
worldwide. The primary concern behind the cloud computing adoption is its privacy and
security. Security can be obtained by using various cryptographic algorithms. Data must be
encrypted before storing them on cloud. Security is the major concern among cloud users
but its performance should also be of higher level. The proposed model consists of hybrid
of AES and Two fish for encryption and ECDH for key generation and key management.
The proposed model is compared with the hybrid of AES and Blowfish on the basis of some
parameters such as encryption/decryption time, upload/download time and throughput with
respect to encryption and decryption.
