Improved cloud data transfer security using hybrid encryption algorithm

Abstract

Cloud computing is a model of sophisticated computing which has a strong effect on data innovation. Cloud computing offers remote access to shared computerized assets in the stored cloud. Operationally cloud servers utilize Web services that give enormus advantage to the user in a variety of applications such as banking and finance, storage, social networking and e-mail. Cloud computing accomplishes many of the features interrelated to elasticity, ease of utility, efficiency and performance with low cost. There are a number of potential concerns related to security and privacy since the requirement to protect cloud computing expanded, the encryption algorithms play the key part in data and information security systems, on side these algorithms consume a considerable quantity of computing resource.This paper,presenting a new hybrid encryption algorithm emphasising on AES and Enhanced Homomorphic Cryptosystem (EHC) as a hybrid encryption to guarantee the secure exchange of data between the user and the cloud server, and compression study for two proficient homomorphic encryption techniques for encoding Data Encryption Standard (DES), Advance Encryption Stander (AES).With The proposed techniques an evaluation has been conducted for those encryption algorithms at diverse file sizes of data, to evaluate time taking for encryption and decryption, throughput, memory consumption and power consumption. The major finding was thats the proposed method has the extremity throughput; memory consumption and our proposed work took advantage of the least time taken in sec for encryption and decryption.

Application of Data Encryption Technology in Network Information Security Sharing

“…One-way encryption that cannot be reversed is adopted for passwords and other authentication information. (2) Data file encryption [12]: to prevent the illegal acquisition of reported information, all reported data files must be encrypted with file encryption software based on the RSA encryption algorithm, and the downloaded data files must be decrypted with a private key. (3) Data storage security [13]: data related to the reported content is encrypted and stored in the database to prevent data leakage caused by database security or internal personnel violations.…”

Improvement security in e-business systems using hybrid algorithm

“…The application of symmetric keys uses a simple symmetric algorithm, and the application of asymmetric keys uses the RSA algorithm, based on two mathematical problems, namely number factorization and modulo operations. The application of this algorithm produces two different keys but connected mathematically [22]. The key for the encryption process is known as the public key and the key used for decryption is the private key.…”

Design and implementation of a secured SDN system based on hybrid encrypted algorithms

“…It is a symmetric-key block cipher [18]. The key length of AES varying between 128, 192, and 256 bits [19]. AES handles 128-bit form plaintext blocks [20].…”
