Abstract
For increasing safety of driving, intelligent vehicles in vehicular ad hoc networks (VANETs) communicate with each other by sending announcements. The existence of a system that guarantees the trustworthiness of these announcements seems necessary. The proposed approach generating announcements should be preserved from internal and external attackers that attempt to send fake messages. In this paper, we use a group-based endorsement mechanism based on threshold signatures against internal attackers. We choose NTRUSign as a public key cryptosystem for decreasing signature generation and verification times. This approach optimizes the network overhead and consequently its performance. In this scheme, also the privacy of signers and endorsers that generate or endorse trustworthy announcements is preserved.
