Self-Authentication In Ho Chi Minh City University of Technology The Iots/Transportation System International Master Program P a g e | iii ABSTRACT With the evolution of the world, technology has become an integral part of a new transportation model called Intelligent Transportation System (ITS).
Within ITS, Vehicular Adhoc Network (VANET) is a crucial infrastructure component that provides features such as traffic monitoring and road safety messages. However, the process of broadcasting is susceptible to privacy threats because the user's identity is transmitted in clear text. Therefore, alongside Connectivity and Bottleneck, Privacy can be seen as a significant challenge in ITS. Privacy and authentication are closely linked, as vulnerabilities can be exposed during anomalous actions followed by successful authentication.
Hence, to protect the privacy, authentication with a Pseudonym-based System is deployed, relying on a Trusted Authority (TA) as a pseudonym supervisor. However, the connection between TA and vehicles can lead to Connectivity or Bottleneck issues in rural and urban areas respectively. As a result, authentication is considered as a front line of defense against Privacy breaches, but Connectivity and Bottleneck concerns necessitate self-authentication, which authenticates independently of TA. The thesis examines Privacy by analyzing related studies and devises an improved self-authentication method to protect it based on Pseudonym-based System and Blockchain.
The proposed scheme employs BLS Signatures for efficient synchronization between different stages of the system, from registration to revocation; while requiring only a single connection to TA during the registration stage.
