Abstract
Cloud computing has expanded significantly in recent years to become one of the major research areas. Aside its numerous benefits, it is also encompassed with challenges most importantly with the issue of data security. In essence, the paper presents an improved technique in ensuring data security in Cloud Computing. This study proposes an enhanced data security model using a two-level cryptographic technique -symmetric (AES) and asymmetric (ECC) cryptographictechnique. This new technique seeks to pass data through thecloud space in a secure way, preventing third parties orintruders from accessing or making meaningful informationout of the data being passed through the cloud space. The paperconsidered the time taken to perform cryptographic operations,enhance the security of data against intruders, denying themfrom having access to the real data enabling the confidentiality,integrity of the data, increasing level of speed with the use ofsmaller keys of ECC in the cryptographic process and increasein the trust level of usage of the Cloud Computing platform.
