The data security in cloud computing is the core problem. Single security method cannot solve the security problem in cloud computing. To advance cloud computing measures to ensure security is important. The solution is the data encryption. Before storing it at virtual location, encrypt the data with keys. User selects the public key to encrypt data and upload the encrypted data to the cloud. This paper introduces a strong cryptography algorithm that provides the security of the data in cloud computing. The proposed algorithm is based on encryption algorithm the hill cipher which was analyzed to be easily breakable if the matrix is known due to its short key length and does not provide any message integrity. So there is the need to make it more typical for the intruder to break it.
