With the assistance of emerging techniques, such as cloud computing, fog computing and Internet of Things (IoT), smart city is developing rapidly into a novel and well-accepted service pattern these days. The trend also facilitates numerous relevant applications, e.g., smart health care, smart office, smart campus, etc., and drives the urgent demand for data sharing. However, this brings many concerns on data security as there is more private and sensitive information contained in the data of smart city applications. It may incur disastrous consequences if the shared data are illegally accessed, which necessitates an efficient data access control scheme for data sharing in smart city applications with resource-poor user terminals. To this end, we proposes an efficient traceable and revocable time-based CP-ABE (TR-TABE) scheme which can achieve time-based and fine-grained data access control over large attribute universe for data sharing in large-scale smart city applications. To trace and punish the malicious users that intentionally leak their keys to pursue illicit profits, we design an efficient user tracing and revocation mechanism with forward and backward security. For efficiency improvement, we integrate outsourced decryption and verify the correctness of its result. The proposed scheme is proved secure with formal security proof and is demonstrated to be practical for data sharing in smart city applications with extensive performance evaluation.

Cloud computing is a diversified domain and is a huge phenomenon that is a widely preferred technology in the current times. The users are unable to utilize cloud computing to the maximum, due to challenges in the security issues. To store sensitive or useful data in an insecure region is not an option for the user. Various techniques have been developed to provide security for the big data in the cloud. During voluminous data transmissions, it will not maintain the end-to-end security and the prevailing approaches do not solve the key complexities and not provides security for the keys. The Attribute-Based Encryption (ABE) can deliver a mechanism of fine-grained control by providing one-to-many encryption. But, the revocable process of accessing the privilege of encrypted data of users from cloud servers is challenging. Further, the complex process of ABE takes up huge computational time hence it becomes a burden for system users. To solve such issues, the proposed Enhanced Cipher-text Policy-based Attribute Encryption (CP-ABE) protect, broadcast and control the access of information, especially over the cloud server. In the proposed Enhanced CP-ABE method, proxy is added to securely transmit the key to the users. The Rivest Shamir Adleman (RSA) Algorithm provides security to outsourced big data in the cloud that enables public key encryption secure data when it is being sent over an insecure network such as the internet. The proposed Enhanced CP-ABE with RSA method effectively identifies the users who decrypt the ciphertexts during decryption. The experimental results show that the proposed Enhanced CP-ABE with RSA Scheme method acquires lesser encryption and decryption times of 1638 ms and 1102 ms respectively for a 256-bit key length. Whereas, the existing methods acquire encryption and decryption times of 1721ms and 1134 ms respectively.

Recently, cloud-based mobile crowdsensing (MCS) has developed into a promising paradigm which can provide convenient data sensing, collection, storage, and sharing services for resource-constrained terminates. Nevertheless, it also inflicts many security concerns such as illegal access toward user secret and privacy. To protect shared data against unauthorized accesses, many studies on Ciphertext-Policy Attribute-Based Encryption (CP-ABE) have been proposed to achieve data sharing granularity. However, providing a scalable and time-sensitive data-sharing scheme across hierarchical users with compound attribute sets and revocability remains a big issue. In this paper, we investigate this challenge and propose a hierarchical and time-sensitive CP-ABE scheme, named HTR-DAC, which is characteristics of time-sensitive data access control with scalability, revocability, and high efficiency. Particularly, we propose a time-sensitive CP-ABE for hierarchical structured users with recursive attribute sets. Moreover, we design a robust revocable mechanism to achieve direct user revocation in our scheme. We also integrate verifiable outsourced decryption to improve efficiency and guarantee correctness in decryption procedure. Extensive security and performance analysis is presented to demonstrate the security requirement satisfaction and high efficiency for our data-sharing scheme in MCS.
