In CloudIoT platform, the data is collected and shared by different nodes of Internet of Things(IoT), and data is processed and stored based on cloud servers.It has increased the abilities of IoT on information computation. Meanwhile, it also has enriched the resource in cloud and improved integration of the Internet and human world. All of this offer advantages as well as the new challenges of information security and privacy protection. As the energy limitation of the nodes in IoT, they are particularly vulnerable. It is much easier to hijack the nodes than to attack the data center for hackers. Thus, it is a crucial and urgent issue to realize the trusted update of authorization of nodes. When some nodes are hijacked, both of the behaviors to upload data to servers and to download information from servers should be forbidden. Otherwise, it might cause the serious damage to the sensitive data and privacy of servers. In order to solve this problem, we proposed a Proxy Re-encryption based Trusted Authorization scheme for nodes on CloudIoT(PRTA). PRTA is based on the proxy re-encryption (PRE), and the cloud server will play the roles of data storing and re-encrypting, which would reach the full potential of cloud computing and reduce the cost of nodes. The node's status is taken as one of the parameters for data re-encryption and it is under the authorization servers' control, which *Manuscript (including abstract) Click here to view linked References could ensure the security and reliability of the data and be beneficial for the privacy protection in CloudIoT. Also, the authorization servers are divided into the downloading and uploading kinds, which will make the application range much wider.

“…If the attributes embedded in the ciphertext fit those held by the user, then he/her decrypts such ciphertext [17]. There are some basic CP-ABE schemes [18][19][20][21]24,27,28,31], in which the size of the ciphertext grows linearly with the number of attributes embedded in access policy. In order to improve efficiency, Emura et al [21] presented a CP-ABE scheme with constant ciphertext size.…”

Most of existing privacy-preserving multi-authorities attribute-based encryption schemes (PP-MA-ABE) only considers the privacy of the user identity (ID). However, in many occasions information leakage is caused by the disclosing of his/her some sensitive attributes. In this paper, we propose a collusion-resisting ciphertext-policy PP-MA-ABE (CRPP-MACP-ABE) scheme with hiding both user's ID and attributes in the cloud storage system. We present a method to depict anonymous users and introduce a managerial role denoted by IDM for the management of user's anonymous identity certificate (Cred AID). The scheme uses Cred AID to realize privacy-preserving of the user, namely, by verifying which attribute authorities (AAs) obtain the blinded public attribute keys, pseudonyms involved in the Cred AID and then distributes corresponding private keys for the user. We use different pseudonyms of the user to resist the collusion attack launched by vicious AAs. In addition, we utilize IDM to cooperate with multiple authorities in producing consistent private key for the user to avoid the collusion attack launched by vicious users. The proposed CRPP-MACP-ABE scheme is proved secure. Some computation and communication costs in our scheme are finished in preparation phase (i.e. user registration). Compared with the existing schemes, our scheme is more efficient.

“…In order to create a SPE scheme supporting disjunctive keyword search, katz et al [14] proposed a public key encryption scheme called inner product encryption (IPE), which is related to the attribute-based encryption (ABE) [30,31]. Recently, in order to better utilize the encrypted data and improve the security, some public key schemes which can support verifiable attribute-based search over outsourced encrypted data are proposed in [32][33][34][35][36][37].…”

Searchable public key encryption scheme is a key technique for protecting data confidentiality in today’s cloud environment. Specifically, public key encryption with conjunctive and disjunctive keyword search (PECDK) can provide flexible search options without sacrificing keywords security and thus attracts a lot of attention nowadays. However, the most effective PECDK scheme is based on the inner product encryption (IPE), which needs more time and space cost. In this paper, by utilizing the bilinear pairing with a prime order group, we propose an efficient PECDK scheme needing less time and storage consumption. The proposed scheme is proven to be secure under a rigorous security definition. The theoretical analysis and experimental results demonstrate that our proposed scheme can significantly improve the time and space efficiency over the state-of-the-art scheme.
