“…In a cloud-supported CV application, distributed and scalable access control schemes are required. Various attribute-based access control models have been presented in the literature (e.g., ciphertext-policy attribute-based encryption [35], secure billing protocol over attribute-based encryption [36]) for preserving confidential information in cloud-supported CV applications. Along with an appropriate access control model, asymmetric or public-key cryptography is necessary for information exchange in cloudsupported CV applications [37]- [40].…”

In an internet-of-things (IoT) environment, cloud computing is emerging as a technologically feasible and economically viable solution for supporting real-time and nonreal-time connected vehicle (CV) applications due to its unlimited storage, enormous computing capabilities, and cost advantage, i.e., cloud computing costs less than owning such systems. However, maintaining cybersecurity is a major challenge in cloud-supported CV applications as it requires CVs and various transportation or non-transportation services to exchange data with the cloud via multiple wired and wireless communication networks, such as long-term evolution (LTE) and Wi-Fi. In this paper, we review the cybersecurity requirements of cloud-supported CV applications, such as confidentiality, integrity, availability, authentication, accountability, and privacy. Our review also identifies the associated cybersecurity challenges that might impact cloudsupported CV applications and corresponding solutions to these challenges. In addition, we present future research opportunities to prevent and mitigate cybersecurity issues in cloud computing for CV-related applications.

“…This scheme is restricted therein it allows an authority merely to issue private keys expressing threshold policies. Since then, several works [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] proposed different ABE systems and applications, among which two worksare remarkable. Goyal et al [6] propounded a fine-grained access constraint for attribute-based encryption.…”

“…In recent years, Li [14] propounded a hidden access policy CP-ABE scheme, which can protect the privacy of the encryptor and decryptor. Guan [16] proposed a conditional CP-ABE which enables data owner to add extra access trees and the corresponding conditions. Jiang [15] proposed a flexible CP-ABE supporting AND-gate and threshold with short ciphertexts.…”

Ciphertext-policy attribute-based encryption (CP-ABE) associates ciphertext with access policies. Only when the user's attributes satisfy the ciphertext's policy, they can be capable to decrypt the ciphertext. Expressivity and security are the two directions for the research of CP-ABE. Most of the existing schemes only consider monotonic access structures are selectively secure, resulting in lower expressivity and lower security. Therefore, fully secure CP-ABE schemes with non-monotonic access structure are desired. In the existing fully secure non-monotonic access structure CP-ABE schemes, the attributes that are set is bounded and a one-use constraint is required by these projects on attributes, and efficiency will be lost. In this paper, to overcome the flaw referred to above, we propose a new fully secure non-monotonic access structure CP-ABE. Our proposition enforces no constraints on the scale of the attributes that are set and permits attributes' unrestricted utilization. Furthermore, the scheme's public parameters are composed of a constant number of group elements. We further compare the performance of our scheme with former non-monotonic access structure ABE schemes. It is shown that our scheme has relatively lower computation cost and stronger security.
