HMEP: Hasten Message Endorsement Protocol for Vehicular Ad hoc Networks

D.Thriveni, G.T.Prasanna Kumari

Vehicular Ad hoc Network (VANET) governs a customer to maintain intelligent transportation system to reduce traffic congestion & Accidents. In presence of Honored Authority message encrypted with receiver’s public key appending with sender’s certificate retraction list and signature. Delay occurs at receiver side due to authenticate the sender’s certification from large size of Certificate Retraction List (CRL) & signature. To reduce this delay we present Hash Message Endorsement Code (HMEC) where the key used to calculate the HMEC is shared only between non-revoked On-Board Units (OBUs) to securely share and update the secret keys. With this we can eradicate Message Endorsement loss compare to previous approach.
