“…Other schemes in Table 2 are small universe schemes, where the public parameter size in our scheme is around 2l shorter than that in [18] and is second only to that in [10]. It is observed that the ciphertext size in [10] and [20] grows linearly with 2 , that the ciphertext size in our scheme and [14] grows linearly with 3 , and that the ciphertext size in [17] grows linearly with 6 . Thus, the ciphertext size in our scheme is the same as that in [14], and is slightly larger than that in [10] and [20], and is much smaller than that in [17] and [18].…”

“…However, their scheme only supports an AND gate access structure, and the size of ciphertext and user private key grows linearly with the size of the entire attribute universe, which makes the scheme inefficient. In addition, Ning et al proposed a traceable CP-ABE scheme realizing the public auditing [19], Guan et al's CP-ABE scheme achieved both traceability and reliable key delegation [20], and Li et al established a traceable CP-ABE scheme with the verifiable outsourced decryption [21].…”

In a ciphertext-policy attribute-based encryption (CP-ABE) system, the decryption keys are only related to attributes shared by multiple users and do not contain any identity information of their original holders. Hence, if a decryption key is leaked, there is no feasible method to trace the suspicious user. The user tracing problem has become an obstacle to the adoption of CP-ABE in practice. In order to address it, some traceable/accountable CP-ABE schemes have been established. However, considering the user tracing problem in multi-domain environment will face new challenges. Multi-domain environments usually have a two-layer structure, domains and intradomain users. When tracing a user, we should first trace the domain where the user is located, and then trace the user in the domain. Unfortunately, the existing traceable CP-ABE schemes only focus on one level of users tracing, and are not suitable for the two-layer structure of multi-domain environments. Therefore, a white-box traceable CP-ABE scheme in multi-domain environment is proposed in this paper. The proposed scheme obtains a so-called two-layer tracing. At the domain level, a short signature technique is used to prevent an attacker from forging the tracing parameter and realize the traceability for domains. Linkable ring signature technology is introduced at the user level to provide a tracing method for users by utilizing the linkability of the signature. The two signature structures are reasonably embedded in a user private key to support two-layer white-box tracing at both domains and intradomain users. The proposed scheme supports any monotone access structures and has full security against chosen plaintext attack in the standard model. Compared with related schemes, the asymptotic communication cost and the asymptotic computation cost of the proposed scheme are relatively low. These advantages make the proposed scheme more practical for solving the user tracing problem in multi-domain environment.INDEX TERMS Ciphertext-policy attribute-based encryption, linkable ring signature, multi-domain environment, two-layer tracing, white-box traceability.

Traceable and Weighted Attribute-Based Encryption Scheme in the Cloud Environment

In order to solve the problem that the importance of the user's attribute is seldom considered in the most of the existing attribute-based encryption schemes with traitor tracing, we designed a traceable and weighted attribute-based encryption scheme. In our constructed scheme, the private key of the user consisting of user's identity information is applied to trace traitors. In addition, the idea of weighted attribute is introduced, and the attributes set is transformed into the segmentation set of weighted attributes through the attributes set segmentation algorithm. Via employing a linear secret sharing scheme, the constructed scheme offers fine-grained and nimble access control mechanism. Under the assumption of q-BDHE in the standard model, we prove that the designed scheme is able to reach security against chosen-plaintext attack. By comparing with other relevant schemes, it has significant improvement in the costs of communication and computation, and it is more suitable for the application of the mobile terminal in cloud computing. INDEX TERMS Attribute-based encryption, access control, traceable, weighted attribute.
