Abstract:

Cloud computing is used to providing many services like data sharing, data storage and platform, infrastructure, software. Services can be change based on the user’s needs. Services can classify as public and private. Private services are used in within the organization. So that private services has the low security challenges. Public services are used by all. Security is the main challenge in public services. Data sharing is the one of the main public services used by the IT industry and many private industries. Data may be the sensitive in industry. Obviously Data sharing in cloud has the security issues. To manage the security issues in data sharing access control mechanisms are used. Attribute based encryption is one of the main access control mechanism which used to ensure the security of the data in the data sharing. Data are shared by the attributes. Here attributes are identified by the key. One of the security issue in data sharing is attribute and data sharing policies are seen by anyone. Key-escrow problem is the one of the security issue in data sharing. Key-escorw is one which is occurred by key provider itself my access the others data. Data sharing has the security issues called revocation. This are three issues in data sharing. To solve this three issues in data sharing have proposed the new attribute based encryption system. New proposed attribute based encryption uses the proxy server which is used to avoid the key- escrow problem. New attribute based encryption solves the revocation problem by reencryption in data sharing. Attributes and policies are hidden in the new proposed attribute based encryption. So that proposed system solves the problems of attributes based encryption in data sharing. This data sharing is secured by new attribute based encryption.
