During the present era, mobiles and smart devices are in abundance. A number of services have been provided through these devices. Ubiquitous services is gaining popularity in the present era. Ubiquity in healthcare is a sector which has gained importance in the current decade, as medical costs are not affordable to the common man. Ubiquitous healthcare has scope in seamlessly monitoring patients and identifying their health conditions. However privacy is at risk when using ubiquitous healthcare as personal health data are given to third party individuals for monitoring, storage and retrieval. This paper proposes a privacy preserving model of an e-health system, so as to maintain the security of patient data across different domains in the e-health system.

Currently, the Internet of Things (IoT) provides individuals with real-time data processing and efficient data transmission services, relying on extensive edge infrastructures. However, those infrastructures may disclose sensitive information of consumers without authorization, which makes data access control to be widely researched. Ciphertext-policy attribute-based encryption (CP-ABE) is regarded as an effective cryptography tool for providing users with a fine-grained access policy. In prior ABE schemes, the attribute universe is only managed by a single trusted central authority (CA), which leads to a reduction in security and efficiency. In addition, all attributes are considered equally important in the access policy. Consequently, the access policy cannot be expressed flexibly. In this paper, we propose two schemes with a new form of encryption named multi-authority criteria-based encryption (CE) scheme. In this context, the schemes express each criterion as a polynomial and have a weight on it. Unlike ABE schemes, the decryption will succeed if and only if a user satisfies the access policy and the weight exceeds the threshold. The proposed schemes are proved to be secure under the decisional bilinear Diffie–Hellman exponent assumption (q-BDHE) in the standard model. Finally, we provide an implementation of our works, and the simulation results indicate that our schemes are highly efficient.

Automated vehicle applications are becoming more and more widespread, and the data security of the vehicle network involved is particularly important. Similar to traditional data, the characteristics of autonomous driving data security are mainly confidentiality, integrity, and availability. If data related to autonomous driving is stolen or tampered with, it will directly cause loss of property or life, which is more harmful than traditional data destruction. To address the security issues on the Internet of Vehicles, we propose an encryption (CP-ABE) scheme which is ciphertext policy attribute-based and lightweight. And it can provide fine-grained access control to data on the Internet of Vehicles with less computational overhead on the device itself, making it ideal for the Internet of Vehicles environment. The scheme also supports key traceability to address the user key leakage problem. Experiments show that the proposed system is effective.
