Abstract: Cloud computing has brought a new revolution to IT industry. In this era, information sharing is more convenient and fast, but applying security mechanism on information while outsourcing it on cloud is challenging. In this paper, we proposed hybrid approach comprising of symmetric and asymmetric algorithm. For encrypting file, we generated optimal and efficient symmetric key using genetic algorithm (GA), further an efficient and secure re-encryption concept has been proposed for ensuring the security of data in unreliable cloud environment. Our results have proved that our proposed approach is more efficient and secured while sharing file with authorised users using cloud in comparison to existing approaches.
