BECSI: Bandwidth Efficient Certificate Status Information Distribution Mechanism for VANETs

Abstract: Abstract. Certificate revocation is a challenging task, especially in mobile network environments such as vehicular ad Hoc networks (VANETs). According to the IEEE 1609.2 security standard for VANETs, public key infrastructure (PKI) will provide this functionality by means of certificate revocation lists (CRLs). When a certificate authority (CA) needs to revoke a certificate, it globally distributes CRLs. Transmitting these lists pose a problem as they require high update frequencies and a lot of bandwidth.

“…Therefore, the status information of each vehicle has to be made available to other vehicles as soon as possible by means of an efficient mechanism. In this kind of networks, many mechanisms have been proposed in recent years to both distribute and issue revocation data [55,56]. The main issue is that none of these studies considers issuing CRL segments independently, according to the number of revoked certificates in a period of time or using a modular operation to distribute those certificates into the CRL segments.…”
