Enhanced DSRC Security

Applications using dedicated short-range communication (DSRC) are being developed to prevent automobile accidents. Many DSRC implementations, applications, and network stacks are not mature. They have not been adequately tested and verified. This study illustrates the security evaluation of a DSRC wireless application in vehicular environments (DSRC/WAVE) protocol implementation. The study team set up a simulation of a working road side unit (RSU) on real DSRC devices. The team's experiments work on the Cohda testbed with DSRC application wsm-channel. The team extended the functionality of wsm-channel, an implementation of WAVE short message protocol (WSMP) for broadcasting GPS data in vehicular communications, to broadcast car information and RSU instructions. Next, the study team performed Denial of Service attacks to determine how few packets needed to be dropped to cause automobile crashes. Hidden Markov Models (HMM) are constructed using sniffed side-channel information since operational packets would be encrypted. The inferred HMM tracks the protocol status over time. To test HMM’s ability to predict which packets will be dropped, the study team used a simulation-based experiment and implemented a DSRC-supported stop light application. Using these simulations, the team was able to show that they could accurately identify the packets they needed to drop by using timing and packet size side channels. The attack simulation using inter-packet delay side-channel features worked best to drop necessary packets with a 2.5 % false-positive rate (FPR) while the attack using a packet size side-channel worked with a 9.5% FPR.
