Secure Ecient Identity-Based Conditional Privacy-Preserving Authentication Protocol for Vehicular Status Message Broadcasting without Bilinear Pairing

Abstract Details

Vehicular Ad-Hoc Networks (V ANETs) allow vehicles to exchange data with each other and with the infrastructure, i.e., Road-Side Units (RSUs). The exchanged data can be classi ed into safety messages, i.e., status messages, or non-safety messages. The status messages contain general information such as the weather conditions, driver's speed, emergency braking, etc. While the non-safety messages contain the private information such as credit payments, driver's personal information, etc. To help improve the vehicular network, Intelligent Transportation System (ITS) requires each vehicle to broadcast one status message every 100-300 ms [39] [71] [23] [22]. V ANET requires vehicles to obtain some credentials to ensure reliability. Only vehicles with valid credentials can broadcast their status messages. However, since the exchanged messages are safety messages, they must be unencrypted. Any vehicle can receive these status messages and accept them after verifying them. The senders must attach their credentials to ensure security requirements such as the message authentication, the privacy and anonymity, and unlinkability and traceability [39] [71] [23] [95] [94]. In Public-Key infrastructure (PKI), the Central Authority (CA) can preload the credentials into the vehicle's limited memory storage or send them through the RSUs via insecure channels. Unfortunately, schemes in PKI are impractical. Vehicles need to broadcast numerous amount of messages. Each message must have a distinct certi cate to ensure unlinkability [95] [94] [22]. Vehicles will consume one certi cate every 100-300 ms [22]. Preloading certi cates periodically from the CA before the deployment or requesting certi cates from the RSU during the deployments may not be practical in networks such as V ANET. The other alternative is the Identity-Based (ID-Based) schemes [14] [13][9] [6] [7] [80]. In the IDBased schemes, vehicles are allowed to user their identities instead of the certi cates. Based on the schemes, vehicles can use their identities to generate their anonymous identities to sign their messages with. However, using identities requires vehicles to perform Bilinear Pairing to authenticate the sender. Bilinear Pairing is complex and impractical in networks with limited bandwidth such as V ANET. Proposing protocols without Bilinear Pairing may require the schemes to use the Tamper-Proof Devices (TPDs). The TPD restricts the randomness of the security complexity of the used crypto-system. In National Institute of Standards and Technology (NIST), the TPD restricts the randomness of the CA's private key from around 1 2192¿264¿1 to 20bytes TPDStorageSize in the non-singular curve P192. In this dissertation, we propose a scheme that does not require a Bilinear Pairing and TPD, and provides the same security requirements. Our scheme provides lower communication and communication costs compared with Bilinear Pairing-free schemes with TPDs. In the second scheme, we show how we can improve the computation and the communication costs further more if we implement a TPD in the authorized vehicles. Both schemes provide ecient message authentication, privacy, anonymity, unlinkability, and traceability. Our schemes provide better communication and communication costs for vehicles to sign and verify status messages. They also do not require any trusted third party to sign and verify message for vehicle-to-vehicle (V 2V ) or vehicle-to-infrastructure (V 2I) during the deployment [22] [90] [95] [94] [30] [39] [71] [114] [115] [41] [100] [10] [23] [20] [38].
