The evolving cloud technology is capable of accommodating volumes of business processes. This feature attracts many individuals and organizations to store their data over cloud. But there are many security issues that require a deep insight. In this research, articles and surveys on cloud security have been reviewed to identify the issues. Efforts have been made to increase cloud data security by devising a hybrid cryptographic algorithm namely Hybrid Elliptic Curve Cryptography -Triple Data Encryption Standard (ECC-TDES). The hybridized algorithms make data more secure and immune to malicious attacks. The proposed algorithm was applied to database of a cloud-based web application and tested with audio, video, image and text files ranging between 10-100 kb file sizes to record performance metrics such as: encryption time, decryption time and accuracy. The recorded parameter values were compared with individual ECC and TDES algorithms. The findings indicated that ECC-TDES takes more time to encrypt/decrypt files but gives highest accuracy with 0.01% error rate.
