Cloud computing is generally recognized as a technology which will have a significant impact on Information Technology in the future. The cloud computing data security has certain drawbacks in its implementation making it insecure. To avoid this problem in this research we propose enhanced security architecture for cloud computing using encryption and decryption system with double key cryptography based on Artificial Neural Network. The objective of the proposed scheme is to protect the

... ion even if the hackers break the cipher text they can't convert cipher text to original text. In our proposed algorithms we have (training algorithm) adopted high data security authorized person can retrieve the data, including key generation, encryption and decryption that are provided in cloud computing system.
