Comparative Analysis on the Performance of Selected Security Algorithms in Cloud Computing

Computer systems security plays a critical role in ensuring the confidentiality, integrity and data protection of electronic resources in a workplace. However, most web information system developers employ algorithms which are inefficient and unsecured. Therefore, organizations adopt security measures that utilize strong encryption and decryption techniques to protect confidential corporate data that reside and are communicated over the Cloud. The purpose of this research is to analyze and compare the performance of selected algorithms namely: AES (Rijndael), Blowfish and RSA. The results show that Blowfish manifested a higher time efficiency ratio when subjected to various data loads and memory size as compared to AES and RSA.
