Performance Evaluation and Analysis of Advanced Symmetric Key Cryptographic Algorithms for Cloud Computing Security

Cloud computing environment is adopted by a large number of organizations, so the rapid transition toward the cloud has fueled concerns on security perspective. Encryption algorithms play the main role in solving such kind of problems in the cloud computing environment. The problem with these encryption algorithms is that they consume a substantial amount of CPU time, memory, and other resources. This paper provides the performance comparison of seven popular symmetric algorithms: AES, DES, 3DES, Blowfish, RC4, IDEA, and TEA. This comparison is done on the basis of encryption time, decryption time, memory usage, flexibility, security, and scalability. The results achieved can be used in cloud-based application and services for the efficient working of cloud computing environment.
