Using IBC and Chameleon Hash for the Confidentiality and Message Authentication in VANET
Abstract:
The transport information security provided by vehicles under VANET environment is quite important. The advantages of the method proposed in the essay are as follows: 1. Communication equipments could validate the information mutually through IBC; 2. Vehicles could validate the legality of public/private key. 3. Vehicles need not show any certificates to validate the identity, so as to avoid the certificates from attacking owing to long-term exposure; 4. The vehicle information could be validated through chameleon method, without waiting for RSU to validate the information, which could improve the instantaneity of the information; 5. The vehicles need not revalidate the identities and consult common key during the time of Hand-off within different RSU ranges.
