“…However, the CSS approach, as presented in [27], is defined over cryptographic pairings limited to the symmetric setting. Symmetric pairings have the disadvantage that they are only viable for practical implementations using obsolete security levels (for example, 80-bit) [28].…”

“…Although the CSS scheme as proposed in [27] is recommended for VANETs security, its definition in the symmetric setting limits its applicability in real scenarios such as smartphones and other smart devices. According to practical realizations of pairing-based encryption [28,36,37], the symmetric pairing is realized by using type A elliptic curves, only efficient for obsolete security levels (80-bit security level or less) according to standards such as NIST [38]. Currently, the recommended security levels are for 112, 128, 192, or 256 bits.…”

“…A way to use increased security levels in pairing-based cryptography is to use the asymmetric setting, usually realized with type F elliptic curves. In [28], the asymmetric setting for pairings was proposed and evaluated in the context of data security in cloud storage. The results achieved showed the efficiency of using asymmetric pairings, in terms of higher security and lower overhead in running time and memory requirements.…”

Vehicular ad-hoc Networks (VANETs) are recognized as a cornerstone of Intelligent Transportation Systems (ITS) to enable the exchange of information among vehicles, which is crucial for the provision of safety-related and entertainment applications. However, practical useful realizations of VANETs are still missing, mainly because of the elevated costs and the lack of a final standardization. In this regard, the feasibility of using smartphones as nodes in VANETs has been explored focusing on small-scale deployments to mainly validate single-hop communication capabilities. Moreover, existing smartphone-based platforms do not consider two crucial requirements in VANETs, namely, multi-hop communication and the provision of security services in the message dissemination process. Furthermore, the problem of securing message dissemination in VANETs is generally analyzed through simulation tools, while performance evaluations on smart devices have not been reported so far. In this paper, we aim to fill this void by designing a fully on-device platform for secure multi-hop message dissemination. We address the multi-hop nature of message dissemination in VANETs by integrating a location-based protocol that enables the selection of relay nodes and retransmissions criteria. As a main distinction, the platform incorporates a novel certificateless cryptographic scheme for ensuring data integrity and nodes’ authentication, suitable for VANETs lacking of infrastructure.

In this paper, we present the design, implementation, and evaluation of an efficient data preparation and retrieval approach for cloud storage. The approach includes a deduplication subsystem that indexes the hash of each content to identify duplicated data. As a consequence, avoiding duplicated content reduces reprocessing time during uploads and other costs related to outsource data management tasks. Our proposed data preparation scheme enables organizations to add properties such as security, reliability, and cost-efficiency to their contents before sending them to the cloud. It also creates recovery schemes for organizations to share preprocessed contents with partners and endusers. The approach also includes an engine that encapsulates preprocessing applications into virtual containers (VCs) to create parallel patterns that improve the efficiency of data preparation retrieval process. In a study case, real repositories of satellite images, and organizational files were prepared to be migrated to the cloud by using processes such as compression, encryption, encoding for fault tolerance, and access control. The experimental evaluation revealed the feasibility of using a data preparation approach for organizations to mitigate risks that still could arise in the cloud. It also revealed the efficiency of the deduplication process to reduce data preparation tasks and the efficacy of parallel patterns to improve the end-user service experience.
