A Secure and Authenticated Key Management Protocol (SA-KMP) for Vehicular Networks

Abstract

Abstract-Public Key Infrastructure (PKI) is the most widely used security mechanism for securing communications over the network. However, there are known performance issues, making it unsuitable for use in the Vehicular Networks (VNs). In this paper, we propose a Secure and Authenticated Key Management Protocol (SA-KMP) to overcome the shortcomings of the PKI. The SA-KMP scheme distributes repository containing the bindings of the entity's identity and its corresponding public key to each vehicle and Road Side Unit (RSU). By doing so, certificate exchanges and Certificate Revocation Lists (CRLs) are eliminated. Furthermore, SA-KMP scheme uses symmetric keys derived based on a 3D matrix based key agreement scheme to reduce the high computational costs of using asymmetric cryptography. We demonstrate the efficiency of the SA-KMP through performance evaluations in terms of transmission and storage overhead, network latency and key generation time. Analytical results show that the SA-KMP is more scalable and outperforms the certificate based PKI. Simulation results indicate that the key generation time of the SA-KMP scheme is less than that of the existing Elliptic Curve Diffie-Hellman (ECDH) and Diffie-Hellman (DH) protocols. In addition, we use Proverif to prove that the SA-KMP scheme is secure against an active attacker under the Dolev and Yao model and further show that the SA-KMP scheme is secure against Denial of Service (DoS), collusion attacks and a wide range of other malicious attacks.

A Console GRID Leveraged Authentication and Key Agreement Mechanism for LTE/SAE

“…The authentication process in LTE networks is primarily handled by EPS-AKA. Firstly, we will discuss the LTE authentication [1,3,5,16] process using EPS-AKA. The LTE being a flat IP-based architecture is more prone to SQL injection, eavesdropping, IP address spoofing, MitM and PII theft [11], hence, the authentication process takes place at UE connection, call initiation, call termination, call handover, area updating etc.…”

“…A considerable volume of research is reported on the authentication [5,[35][36][37][38][39][40][41]48] and on key agreement [18,[42][43][44][45][46] process to overcome the security gap that needs improvement in the recently proposed symmetric [13], and asymmetric security solutions [17]. Machine learning based authentication [2,4,46] and aggregation [47] is proposed to overcome the security flaws in the dynamic environments.…”

“…The EPC framework includes LTE radio base stations (eNB) [31,47] that connect to the control plane components such as > TII-17-2276 < 4 MME, User Plane Gateways such as Packet Data Network Gateway (PDN-GW) & Serving GW (SGW). The MME acts as a Key Distributor (KD) [3][4][5][6][7][8][9] in the LTE. The EPS network holds both MME and SAE [1,2] and connects these two to the E-UTRAN entities over the many-to-many interface via HSS.…”

“…To prevent eavesdropping and other attacks on the radio interface, the IMSI is sent as rarely as possible. Unique identity of a subscriber is known through the IMSI that helps to fetch the user subscribed services and location [1][2][3][4][5][6]12]. As shown in Fig.…”

STEIM: A Spatiotemporal Event Interaction Model in V2X Systems Based on a Time Period and a Raster Map

“…Vehicles run in a complex environment in real time. us, complex event-processing technology is required to filter the massive data stream generated by event instance flows to obtain those that concern the user via an eventprocessing model [10,11]. Events that concern users are sent to a client events library or disposed of based on a user's predefined rules.…”
