The Key Policy Attribute Based Encryption provides how to maintain integrity, confidentiality and availability to share data with others. It generates encryption, decryption time along with file size and file type. Proposed work explains encryption with Attribute Based encryption then file is spitted into chunks. Hash key is generated for every data chunk which is unique. Secure hash algorithm is used for generation of hash key. Proposed algorithm gives confidentiality to work as it is a public key encryption algorithm of cryptography. It is also asymmetric i. e. key set is used for data encryption and decryption. Data is stored on cloud means it is available to everyone through Cloud space. Key generated for encryption and decryption is runtime. Key policy attribute based encryption reduces encryption time by 35 % and decryption time by 65 %.
