Trusting Testcases Using Blockchain-Based Repository Approach

Abstract

Modern vehicles have evolved to support connected and self-driving capabilities. The concepts such as connected driving, cooperative driving, and intelligent transportation systems have resulted in an increase in the connectivity of vehicles and subsequently created new information security risks. The original vehicular ad-hoc network term is now emerged to a new term, Internet of Vehicles (IoV), which is a typical application of symmetry of Internet of Things (IoT). Vehicle manufacturers address some critical issues such as software bugs or security issues through remote updates, and this gives rise to concerns regarding the security of updated components. Moreover, aftermarket units such as those imposed by transportation authorities or insurance companies expose vehicles to high risk. Software testing aims to ensure that software products are reliable and behave as expected. Many commercial and open-source software products undergo formal certifications to increase users’ confidence in their accuracy, reliability, and security. There are different techniques for software certification, including test-based certification. Testcase repositories are available to support software testing and certification, such as the Linux Test Project for Linux kernel testing. Previous studies performed various testing and experimental evaluation of different parts of modern vehicles to assess the security risks. Due to the lack of trusted testcase repositories and a common approach for testing, testing efforts are performed individually. In this paper, we propose a blockchain-based approach for a testcase repository to support test-based software and security testing and overcome the lack of trusted testcase repositories. The novel concept Proof-of-Validation to manage global state is proposed to manage updates to the repository. The initial work in this study considers the LTP test suite as a use case for the testcase repository. This research work is expected to contribute to the further development in including evidence generation for testing verification.

Overview of Blockchain Oracle Research

“…Works in the transport sector have focused on the security, privacy [125], [128], and efficient identification of vehicles [129], as well as data processing for intensive transport environments, such as commercial waterways [130]. Whereas the work from Khalifa University discussed the implementation of Chainlink for autonomous vehicle test-case repositories, the works from other universities proposed their own oracle design for efficient data transmission in the transport industry.…”

“…The Internet of Vehicles (IoV) domain has concentrated on supporting connected and self-driving capabilities, including connected driving, cooperative driving, and intelligent transportation systems While this innovation increases conveniences, it has subsequently created new information security risks such as software bugs and vulnerable remote updates. Hence, in the paper "Trusting Testcases Using Blockchain-Based Repository Approach" [3], Zaabi et al proposed a blockchain-based approach as a trusted testcase repository to support test-based software and security testing. A new concept, called Proof-of-Validation, is proposed as a non-incentivized consensuses mechanism with global state information, which can be used to manage updates to the repository under the adoption of test suite provided by Linux Test Project (LTP).…”

Blockchain-Based Access Control in a Globalized Healthcare Provisioning Ecosystem

“…Although resource attributes do exist in the blockchain as in-chain data stored in RSC, environmental attributes are off-chain data that PDP needs to retrieve. Ethereum provides the mechanism for off-chain data retrieval, called oracles [63], which enables DSC to interact using APIs and query real-world information to retrieve all necessary attributes. All transactions and events processed by EPP are stored in the blockchain to form a detailed audit log.…”
