Cloud computing plays a major role in sharing data and resources to other devices through data outsourcing. During sharing resources, it is a challenging task to provide access control and secure write operations. The main issue is to provide secure read and write operations collaboratively and to reduce computational overload by effective key management. In this paper, a secure and an efficient data collaboration scheme blowfish hybridized weighted attribute-based Encryption (BH-WABE ) for secure data writing and proficient access control has been proposed. Here, weight is assigned to each attribute based on its importance and data are encrypted using access control policies. The cloud service provider stores the outsourced data and an attribute authority revokes or updates the attributes by assigning different attributes based on the weight. The receiver can access the data file corresponding to its weight in order to reduce the computational overload. The proposed BH-WABE provides collusion resistance, multiauthority security and fine-grained access control in terms of security, reliability, and efficiency. The performance is compared with the conventional hybrid attribute-based encryption (HABE) scheme in terms of data confidentiality, flexible access control, data collaboration, full delegation, partial decryption, verification, and partial signing.

“…It can not only be regarded as a service-oriented model, but also a fundamental model of branches and iterations to be further extended. Our future work will focus on the model simplification, sub-model discovery, and related application in GP unification , information security [22], search-based software engineering [19], and some challenge problems [23], etc.…”

“…Unfortunately, the verifiability of the cloud's transformation is not guaranteed for users. By offloading all the access policy and attribute related operation to the key generation service provider (KGSP) and the decryption cloud server provider (DSP), respectively, a secure OABE scheme, which was introduced by Li et al [18], supplied checkability with supporting both outsourced key issuing and decryption. Presently, Lai et al [19] formally defined the verifiability of ABE and presented an ABE scheme with verifiable outsourced decryption.…”

Online healthcare social networks (OHSNs) play an essential role in sharing information among medical experts and patients who are equipped with similar experiences. To access other patients' data or experts' diagnosis anywhere and anytime, it is necessary to integrate the OHSN into the Internet as part of the Internet of Things (IoT). Therefore, it is crucial to design an efficient and versatile access control scheme that can grant and revoke a user to access the OHSN. In this paper, we propose novel attribute-based encryption (ABE) features with user revocation and verifiable decryption outsourcing to control the access privilege of the users. The security of the proposed ABE scheme is given in the well-studied random oracle model. With the proposed ABE scheme, the malicious users can be excluded from the system and the user can offload most of the overhead in the decryption to an untrusted cloud server in a verifiable manner. An access control scheme for the OHSN has been given in the context of the IoT based on the proposed ABE scheme. The simulation demonstrates that our access control mechanism is practical.
