Lately, an ever increasing number of users and enterprises have endowed information stockpiling and stage development to proxy cloud service providers (PCSP) through the cloud innovation. In this regard, attribute-based encryption (ABE) mechanisms can compensate for the shortcomings of traditional encryption with flexible and flexible anti-collusion access policies. However, there is a security problem in the access policy, which requires files to be updated in the practical application. At ABE there are problems with over- calculation, storage costs. In this paper, an effective cipher text strategy suggests an ABE scheme with policy updates and file updates in cloud computing. The cipher text component generated by the first encryption can be shared during policy updates and file updates. Reduce client’s storage and communication costs as well as PCSP computing costs. Furthermore, the proposed scheme turns out to be valid assuming a Diffie-Hellman q-parallel bilinear exponential (BDHE) solution. Finally, experimental simulations show that the proposed scheme is very effective in terms of policy updates and file updates.
