영문 초록

A vehicular ad hoc network (VANET) uses cars as mobile nodes in a MANET to create a mobile network. In the vehicular ad hoc networks the security is an important concern. For security, Vehicular ad hoc networks (VANETs) adopt the Public Key Infrastructure (PKI) and Certificate Revocation Lists (CRLs). In the Public Key Infrastructure system, the authentication of a received message is performed by checking if the certificate of the sender is included in the current Certificate Revocation Lists (CRLs) and verifying the authenticity of the certificate and signature of the sender. But it takes more time for CRL checking process. So, in order to overcome this problem we use an efficient revocation check process in EMAP uses a keyed Hash Message Authentication Code (HMAC), where the key used in calculating the HMAC is shared only between non-revoked On-Board Units (OBUs). In addition, EMAP uses a novel probabilistic key distribution, which enables non-revoked OBUs to securely share and update a secret key. By using this method we significantly reduces the message loss ratio. But in this method generating and verifying such signatures can cause high computational overhead. So, to conquer this trouble we introduce an innovative technique called ASIA as an Accelerated Secure In-network Aggregation strategy that can accelerate message verifications and significantly reduce computational overhead while retaining satisfactory security. ASIA can largely accelerate message verifications and drastically reduce computational and communication overhead compared to existing schemes.
