“…These massive amounts of health data collected by IoT wearable devices are required to be safely transferred and stored in CSS [7,8]. Thus, it can allow the authorized relevant parties (such as caretakers or doctors) to safely access these sensitive and privacy data [14,15] and apply different analytical techniques However, EC bring two new problems, namely data repair (DR) and data update (DU). In DU, since each parity block is a linear combination of multiple data blocks, once the data block is updated, the relevant parity blocks must also be updated to achieve data consistency.…”

To achieve the high availability of health data in erasure-coded cloud storage systems, the data update performance in erasure coding should be continuously optimized. However, the data update performance is often bottlenecked by the constrained cross-rack bandwidth. Various techniques have been proposed in the literature to improve network bandwidth efficiency, including delta transmission, relay, and batch update. These techniques were largely proposed individually previously, and in this work, we seek to use them jointly. To mitigate the cross-rack update traffic, we propose DXR-DU which builds on four valuable techniques: (i) delta transmission, (ii) XOR-based data update, (iii) relay, and (iv) batch update. Meanwhile, we offer two selective update approaches: 1) data-deltabased update, and 2) parity-delta-based update. The proposed DXR-DU is evaluated via trace-driven local testbed experiments. Comprehensive experiments show that DXR-DU can significantly improve data update throughput while mitigating the cross-rack update traffic.

“…Currently, ABE is commonly used for secure access control of data on the cloud. [4][5][6][7] Although the ABE scheme is used to implement fine-grained access control, its computational overhead is not low, and these calculations are inefficient for an IoT system with limited storage and computational capacity, and the real-time requirements of data response for Internet of Vehicles are extremely strict. In addition, the characteristics of the Internet of Vehicle devices lead to their vulnerability to attacks and key leakage, so the handling of the keys after leakage is also an urgent issue to be dealt with.…”

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.

“…Therefore, by adopting IPE, one can realize multiple kinds of flexible access control using only a single cryptographic primitive. Recently, more applications for IPE have been developed, e.g., privacy-preserving video streaming [21], access control for WBAN [22], secure keyword searching [23] and outsourced data integration [24]. It shows the possibility for the application of IPE in various environments.…”

With the rise of technology in recent years, more people are studying distributed system architecture, such as the e-government system. The advantage of this architecture is that when a single point of failure occurs, it does not cause the system to be invaded by other attackers, making the entire system more secure. On the other hand, inner product encryption (IPE) provides fine-grained access control, and can be used as a fundamental tool to construct other cryptographic primitives. Lots of studies for IPE have been proposed recently. The first and only existing decentralized IPE was proposed by Michalevsky and Joye in 2018. However, some restrictions in their scheme may make it impractical. First, the ciphertext size is linear to the length of the corresponding attribute vector; second, the number of authorities should be the same as the length of predicate vector. To cope with the aforementioned issues, we design the first decentralized IPE with constant-size ciphertext. The security of our scheme is proven under the ℓ-DBDHE assumption in the random oracle model. Compared with Michalevsky and Joye’s work, ours achieves better efficiency in ciphertext length and encryption/decryption cost.
