“…To grant multiple users the search capabilities and access privileges, user authorization should be enforced. Therefore, the authors of [34] proposed a searchable CP-ABE scheme. In their scheme data owner encrypts the sensitive data under an access policy before outsourcing sensitive data in the public cloud and builds a corresponding secure index for keywords.…”

Abstract. Ciphertext policy attribute based encryption (CP-ABE) is a technique in which a user with secret key containing attributes is only able to decrypt the message if the attributes in the policy match with the attributes in secret key. Therefore, CP-ABE is suitable for some interesting applications such as cloud computing which requires both security assurances and access control over encrypted data simultaneously. However, we observed that all existing CP-ABE schemes entail a limitation that, if an authorized user wants to search for an encrypted file having particular keywords, then he has to first download and then decrypt the file before searching for particular keywords. When applied to an application involving a cloud, because the number of files on the cloud is likely to be huge, all these process results in large overhead for user.Therefore, to overcome this limitation, we proposed a new searchable CP-ABE scheme in this paper, that allows the authorized user to check whether the ciphertext contains specific set of keywords or not, using his own token without decrypting the message. The label and keywords attached with ciphertext and secret key respectively, do not reveal any information about the data unless given the authorized token. In addition, our proposed scheme provides receiver anonymity also. The security analysis shows that privacy in this new solution is achieved with an overwhelmingly large probability. Equipping CP-ABE scheme with keyword-searching capability reduces the searching time of ciphertext having particular keywords. To the best of our knowledge ours is the first efficient collusion resistant searchable CP-ABE scheme with hidden ciphertext policy which uses few and fixed number of pairing operation in key word search as well as decryption algorithm.

“…EFFICIENCY In this section, we compare the efficiency of our schemes with the schemes in [3] and [5]. Our basic scheme is as efficient as the improved scheme, except the generation of SK and the decryption in KP-ABE (which are similar to those of [3] and [5] under the same search policy). This is because that the main difference between our basic and improved schemes is that we apply different KP-ABE schemes to build the secure index.…”

“…This is because that the main difference between our basic and improved schemes is that we apply different KP-ABE schemes to build the secure index. Therefore, we mainly compare the efficiency of our improved scheme with the schemes in [3] and [5]. Further, since the schemes in [3] and [5] do not support data access control, we will not consider the cost of data encryption and decryption in our comparison result.…”

As more and more data is outsourced to cloud which is assumed to be a semi-trusted server, it is necessary to encrypt the sensitive data stored in the cloud. However, it brings a series of problems, such as: How to search over the encrypted data efficiently and securely? How should a data owner grant search capabilities to the data users? To solve these problems, we propose two attribute-based keyword search and data access control schemes based on public-key searchable encryption and attribute based encryption. Our solutions allow a data owner to control the access policy and grant the search policy to any data user who wants to retrieve the encrypted data efficiently.
