To provide a secured access control using combined hybrid key-ciphertext attribute based encryption (KC-ABE)

Cloud computing security is defined as the self of polices & control based methodologies. It is designed to protect data, information, and infrastructure used to regulate compliances. In cloud computing, we are using many types of encryption technique. Particularly ABE technique is divided into KP-ABE & CP-ABE to make the efficient content transformation. In KP-ABE, the design of ciphertexts and user keys are with a group of descriptive attributes and policies respectively. The key issuer only can justify the access control, and it cannot issue by the encryptor. So, key generation time and encryption time will be more. In CP-ABE, the encryptor has to take a decision on who have authority to access or encrypt data. To overcome the drawback of KP-ABE, more solution have launched earlier. But now new encryption technique has proposed in this paper. In proposed system, a new hybrid KC-ABE algorithm has generated to improve the process of KP-ABE regarding of secure connection. Through this algorithm also we can achieve less encryption time and key generation time to improve an efficiency of KP-ABE.
