Cloud computing is a popular area of research for inventors. And it is very important in data sharing applications. On cloud the data being shared must be secure. The flexibility and the efficiency of the data are depending upon the security parameter. To achieve this purpose they describe new algorithm which depends upon public key cryptography and produce constant size cipher text. These ciphers can be decrypt by using a secret key. This secret key can develop the constant size key known as aggregate key, for selection of flexible choices of ciphers. The other encrypted files except this cipher remain private. The authors can able to save this aggregate key or can send it to others for further data sharing.
