Securing Cloud Services using Identity Based Encryption


Cloud computing provides a flexible and convenient way for data sharing bringing various benefits for both the society and individuals. A natural resistance exists for users to directly outsource the data to the cloud since the data often contain important information. Thus, it is necessary to place access control on the shared data. Identity-based encryption is a promising cryptographical primitive to build a practical data sharing system. However, access control is not static which means that when some user’s authorization is expired, there should be a mechanism that can remove him/her from the system. Consequently, the revoked user cannot access both the previously and subsequently shared data. To this end, a notion was proposed which was known as revocable storage identity-based encryption. It can provide the forward/backward security of ciphertext by introducing the functionalities of user revocation and ciphertext update simultaneously. The performance comparisons indicate that the proposed scheme has advantages in terms of functionality and efficiency, and thus is feasible for a practical and cost-effective data-sharing system.
