摘要：Cloud computing offers aprominent service for data storage known as cloud storage. The flow and storage of data on the cloud environment in plain text format may be main security threat. So, it is the responsibility of cloud service providers to ensure privacy and security of data on storage as well as network level. The following three parameters confidentiality, integrity and availability decide whether security and privacy of data stored on cloud environment is maintained or not. The proposed work is to define cloud architecture with configured samba storage and cryptographic encryption techniques. The cloud architecture deployed with samba storage uses operating system feature specifying permission values for three attributes (User/Owner, Group and Global) and maps it to cryptographic application which performs cryptographic operations. Cryptography application supports symmetric and asymmetric encryption algorithm to encrypt/decrypt data for uploading/downloading within cloud storage. A username and password based authentication mechanism for users and digital signature scheme for data authenticity are defined within cloud architecture
