“…Starting with the work of Boneh et al [13][14][15], searchable encryption has also been considered in the public key setting [10,[16][17][18][19]. The early works lack function privacy until the first definition was suggested very recently by Boneh et al [20].…”

Content Centric Networking (CCN) is an effective communication paradigm that well matches the features of wireless environments. To be considered a viable candidate in the emerging wireless networks, despite the clear benefits of locationindependent security, CCN must at least have parity with existing solutions for confidential and anonymous communication. This paper designs a new cryptographic scheme, called Asymmetric Index Encapsulation (AIE), that enables the router to test whether an encapsulated header matches the token without learning anything else about both of them. We suggest using the AIE as the core protocol of anonymous Content Centric Networking. A construction of AIE which strikes a balance between efficiency and security is given. The scheme is proved to be secure based on the DBDH assumption in the random oracle with tight reduction, while the encapsulated header and the token in our system consist of only three elements.

“…However, the first identity-based encryption (IBE) construction was put forward in the literature [23] until 2001. Subsequently, many IBE schemes were proposed [24,25]. By leveraging the idea of IBE, Delerablée [26] raised identity-based broadcast encryption (IBBE), which can be deemed as a special type of PKBE.…”

Cloud computing is now a widespread and economical option when data owners need to outsource or share their data. Designing secure and efficient data access control mechanism is one of the most challenging issues in cloud storage service. Anonymous broadcast encryption is a promising solution for its advantages in the respects of computation cost and communication overload. We bring forward an efficient anonymous identity-based broadcast encryption construction combined its application to the data access control mechanism in cloud storage service. The lengths for public parameters, user private key and ciphertext in the proposed scheme are all constant. Compared with the existing schemes, in terms of encrypting and decrypting computation cost, the construction of our scheme is more efficient. Furthermore, the proposed scheme is proved to achieve adaptive security against chosen-ciphertext attack adversaries in the standard model. Therefore, the proposed scheme is feasible for the system of data access control in cloud storage service. .

Summary Cloud computing is an efficient tool in which cloud storage shares plenty of encrypted data with other data owners. In existing cloud computing scenarios, it may suffer from some new attacks like side channel attacks. Therefore, we are eager to introduce a new cryptographic scheme that can resist these new attacks. In this work, we exploit a new technique to build leakage‐resilient identity‐based encryption and use the stronger existing partial leakage model, such as continual leakage model. More specifically, our proposal is based on the underlying decisional bilinear Diffie‐Hellman assumption, but proven adaptively secure against adaptive chosen ciphertext attack in the standard model. Above all, a continuous leakage–resilient IBE scheme with adaptive security meets cloud computing with stronger security.
