“…In addition, DG-APED is not only providing errordetection and fault tolerance, but also is efficient in terms of communication and computation overhead compared to the schemes. The author in [17] considered one aggregator and users (customers) equipped with an electricity smart meter. Based on two phases, namely 1) meter's reading report and 2) privacy-preserving aggregation.…”

The progressions made in the savvy meters have empowered the mechanized procedure of the charging arrangement of purchaser electrical utilization. So as to mechanize the errand of charging frameworks, cloud based charging model has been recommended. This sort of open source model can be effortlessly recognizable and altered by the outsider assailants. Henceforth, information security is the major worry amid information procurement and transmission process. This paper devises the cipher text arrangement–Attribute Based Encryption(CP-ABE) for accomplishing productive and anchored information learning show for the shrewd matrix frameworks. A community oriented key is produced for unscrambling the information for the approved client that upgrades the security of the framework. At first, they got information is protected with the entrance control approaches. The information proprietor who has the synergistic key can get to the touchy information or disaster will be imminent, the trait repudiation show confines the information consent. Thus, we can reluctantly illuminate the key escrow issues with diminished capacity utilization in the cloud information sharing frameworks. Trial examination has demonstrated the productivity of the proposed CP-ABE as far as time taken for key age, encryption and unscrambling process. It delineates that the proposed CP-ABE performed better.

“…Afterwards, Yang et al [ 22 ] presented a CP-ABE scheme that were supporting attribute revocation, in which attribute authority was responsible for updating ciphertexts and non-revoked data users' corresponding secret keys related to revoked attribute. In 2014, Xiong et al [ 23 ] put forward a CP-ABE scheme that supporting universe attribute revocation, which was built on multiple minimum attribute sets of sharing re-encryption keys. When a universe attribute needs to be revoked, the cloud server performs the operation of re-encrypted ciphertext.…”

We propose an attribute-based encryption scheme with multi-keyword search and supporting attribute revocation in cloud storage environment, in which binary attributes and AND-gate access policy are used. Our proposal enjoys several advantages. Firstly, multi-keyword search is available, and only when a data user's attribute set satisfies access policy in keyword index, and keyword token generated by data user matches index successfully, then data user can obtain ciphertext containing keywords. In this way, more accurate keyword search is achievable. Secondly, the search privacy of data user is protected owing to cloud servers cannot obtain any knowledge of keywords which data user is interested in. Meanwhile, the ciphertext is able to be decrypted when data user's attribute set satisfies access policy specified in the ciphertext, which can both improve security of encryption and achieve secure fine-grained access control. Thirdly, the proposed scheme supports attribute revocation, in our scheme when a data user's attribute is revoked, the version number of attribute, non-revoked data users' secret keys and related ciphertexts will be updated, such that data user whose attribute is revoked does not decrypt updated ciphertext anymore. In addition, based on the assumption of decisional linear (DL) and decisional Diffie-Hellman (DDH), our scheme is proved to be secure against selectively chosen-keyword attacks and selectively chosen-plaintext attacks respectively, and it also ensures token privacy security.
