Cooperative Message Authentication Protocol(CMAP) in VANETMayuresh Bhagat
VANETs allow vehicles to communicate with each other to share information about traffic and road conditions. This addresses issues like lack of timely accident alerts. A VANET uses vehicle-to-vehicle communication through wireless networks to provide drivers with real-time traffic updates. It allows vehicles to broadcast safety messages to nearby vehicles to warn of hazards. Cooperative message authentication protocols help verify these messages efficiently through distributed verification. VANET research focuses on security, routing protocols, applications for safety and convenience, and reducing computational overhead of verification.
This document presents a proposed improved safety information routing protocol for vehicular ad hoc networks (VANETs). The proposed protocol uses spray and wait and direct delivery routing to transmit data between nodes. It calculates traffic density based on vehicle length, safety distance, and road dimensions. The protocol establishes routes from source to destination nodes. Simulation results show that the spray and wait router performs better than the direct delivery router in terms of delivered messages and overhead ratio. The proposed protocol can help reduce delays in VANET safety message routing.

This document proposes a Distributed Malicious Node (DMN) algorithm to detect and isolate malicious nodes in a Vehicular Ad-hoc Network (VANET). The algorithm uses a distributed approach where vehicles monitor each other to detect abnormal packet dropping or duplicating behavior.

The cluster head updates distrust values and isolates malicious nodes from the network if their distrust exceeds a threshold. Simulation results show the DMN algorithm improves network performance metrics like throughput, packet delivery ratio, and end-to-end delay compared to no detection.

Performance evaluation for vehicular ad-hoc networks based routing protocolsjournalBEEI
VANET is a branch of MANETS, where each vehicle is a node, and a wireless router will run. The vehicles are similar to each other will interact with a wide range of nodes or vehicles and establish a network. VANETs provide us with the infrastructure to build new solutions for improving safety and comfort for drivers and passengers. There are several routing protocols proposed and evaluated for improving VANET's performance. The simulator is preferred over external experience because it is easy, simple, and inexpensive. In this paper, we choose AODV protocol, DSDV protocol, and DSR protocol with five different nodes density. For each protocol, as regards specific parameters like (throughput, packet delivery ratio, and end- to- end delay). On simulators that allow users to build real-time navigation models of simulations using VANET. Tools (SUMO, MOVE, and NS-2) were used for this paper, then graphs were plotted for evaluation using Trace-graph. The results showed the DSR is much higher than AODV and DSDV, In terms of throughput. While DSDV is the best choice because of the low average end to end delay. From the above, we conclude that each strategy has its own negative and positive aspects that make it ideally suited to a particular scenario than other scenarios.

Emap expedite message authentication protocol for vehicular ad hoc networksIEEEFINALYEARPROJECTS
EMAP is an expedited message authentication protocol proposed for vehicular ad hoc networks (VANETs). It replaces the time-consuming process of checking large certificate revocation lists (CRLs) with a more efficient revocation checking process using hashed message authentication codes (HMACs). Only non-revoked vehicles can securely share and update the secret HMAC key. EMAP significantly reduces message loss due to authentication delays compared to conventional CRL-based authentication methods. It provides security properties like entity authentication, message integrity, and resistance to colluding attacks, while enabling fast authentication through its novel key distribution and revocation checking scheme.
This document proposes an Expedite Message Authentication Protocol (EMAP) for vehicular ad hoc networks (VANETs) that aims to significantly decrease message loss ratio due to message verification delay compared to conventional authentication methods using certificate revocation lists (CRLs). EMAP replaces the time-consuming CRL checking process with a more efficient revocation checking process using hash-based message authentication codes (HMACs) shared only between valid vehicles. It also uses a novel probabilistic key distribution method to securely share and update keys.
Vehicular Ad Hoc Network (VANET) is a more influential network in which vehicles depend on each other to communicate and for the secure exchange of the messages. With the improvement in the technology, mainly the vehicles are equipped with Wi-Fi and GPS devices to improve the traffic handling and road safety. But many vehicles may broadcast the bogus messages for their own purpose, so it needs a trustful environment and an effective trust management schemes to prevent the network from the various malicious attacks. Trust establishment is very challenging as the network is highly mobile and vehicles may come in or depart at any time. In this paper, we first discuss the VANET model to describe the environment, and then the trust management schemes to secure the network and lastly the various cryptography fundamentals for the fast and safe message transfer.

EMAP is an expedite message authentication protocol proposed for vehicular ad hoc networks (VANETs). It replaces the time-consuming process of checking certificate revocation lists (CRLs) during message authentication with a more efficient revocation checking process using keyed hash message authentication codes (HMACs). In EMAP, only non-revoked vehicles can securely share and update a secret key used to calculate the HMACs. This allows EMAP to significantly decrease message loss due to authentication delays compared to conventional methods using CRLs.

Improving Security Features In MANET Authentication Through Scrutiny Of The C...Editor IJMTER
With changing times, the researchers fine MANET Security, a daunting task.
Authentication problems are crapping up frequently, in the Absence of well laid out of infrastructure
.The adaptability of TTP’s and non TTP’s in MANET’s becoming more difficult and impractical.
With the help of pre assigned logins on offline basis and issuance of certificates more effectively
can address with the help of Hybrid Key management Scheme on strength and use of 4G services.
The proper account of CRL status of servers was not taken into by the scheme. if it is embedded
the nodes need to check frequently the server’s CRL status for authenticating any node and place
external messages outside MANET which leads to overheads. To reduce them , we tried by going for
online MANET authority ,responsible for issuing certificates ,duly considering the CRL Status of
servers ,their renewable and key verification within the MANET, which had sufficiently reduced the
external messages.
LSKA-ID: A lightweight security and key agreement protocol based on an identi...TELKOMNIKA JOURNAL
Recently, a huge effort has been pushed to the wireless broadcasting nature in the open area. However, the vehicular ad hoc network (VANET) is disposed to various kinds of attacks. Hence, keeping the security in VANET is the most critical issue because of the VANET network related to human life. Thus, we propose a robust and lightweight security and key agreement-based identity protocol LSKA-ID for vehicular communication. Our protocol utilizes the elliptic curve cryptography, Chinese reminder theorem, and identity (ID)-based cryptosystem to resolve the issues found in the previously proposed schemes, in which our protocol can resolve the key escrow issues accompanied in most ID-based schemes. Also, it does not need batch verification operations, which cause some problems to the verifier in case the batch beacons have one or more illegal beacons. Moreover, the LSKA-ID protocol addresses the dependency on the trusted authority (TA) during the high frequent handover between the groups that may cause a bottleneck problem on the TA. The security analysis proves the correctness of the LSKA-ID protocol by using the random oracle model and has shown to be effective in a performance evaluation.

Blockchain-Based Secure and Scalable Routing Mechanisms for VANETs ApplicationsIJCNCJournal
The VANET has seen a boom in the distribution of significant source data,enabling connected vehicle communications to enhance roadway safety.Despite the potential for interesting applications invehicle networks,thereare still unresolved issues that have the potential to hinder bandwidth utilization once deployed. Specifically, insider assaults on VANET platforms such as Blackhole attemptscan completely stop vehicle-to-vehicle communications and impair the networks' performance level. In this study, we provide the blockchain-based decentralized trust scoring architecture for the participants in the network to identify existing and blacklisted insider adversaries in VANET. To address this concern, we suggest a two-level detection technique, in the first level neighboring nodes determine theirtrustworthiness and in the second level it aggregates trust scores for vehicle nodes using a consortium blockchain-based mechanism that uses authorized Road Side Units (RSUs) as consensus mechanism. The blacklisted node records are then periodically changed based on the trust scores supplied by the nearby nodes. In regards to the practical scope of the network, the experimental study demonstrates that the suggested solution is effective and sustainable. To improve packet delivery ratio and vehicle node security in the VANET, the blockchain-based Trust-LEACH routing technique has also been created. The performance analysis has been carried out for Computational cost analysis, Computational time for block creation, Network analysis, SecurityAnalysis, and MITM attack analysis. Additionally, we provide proof that the suggested approach enhances VANET reliability by thwarting and removing insider threat initiation nodes from its blacklist.

A Computational Analysis of ECC Based Novel Authentication Scheme in VANET IJECEIAES
A recent development in the adhoc network is a vehicular network called VANET (Vehicular Adhoc Network). Intelligent Transportation System is the Intelligent application of VANET. Due to open nature of VANET attacker can launch various kind of attack. As VANET messages are deal with very crucial information’s which may save the life of passengers by avoiding accidents, save the time of people on a trip, exchange of secret information etc., because of this security is must be in the VANET. To ensure the highest level of security the network should be free from attackers, there by all information pass among nodes in the network must be reliable i.e. should be originated by an authenticated node. Authentication is the first line of security in VANET; it avoids nonregistered vehicle in the network. Previous research come up with some Cryptographic, Trust based, Id based, Group signature based authentication schemes. A speed of authentication and privacy preservation is important parameters in VANET authentication. This paper addresses the computational analysis of authentication schemes based on ECC. We started analysis from comparing plain ECC with our proposed AECC (Adaptive Elliptic Curve Cryptography) and EECC (Enhanced Elliptic Curve Cryptography). The result of analysis shows proposed schemes improve speed and security of authentication. In AECC key size is adaptive i.e. different sizes of keys are generated during key generation phase. Three ranges are specified for key sizes small, large and medium. In EECC we added an extra parameter during transmission of information from the vehicle to RSU for key generation. Schemes of authentications are evaluated by comparative analysis of time required for authentication and key breaking possibilities of keys used in authentication.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Most of the existing works overlooked the authentication delay resulting from
checking the CRL for each received certificate.
•
It introduce an expedite message authentication protocol (EMAP) which replaces
the CRL checking process by an efficient revocation checking process using a fast
and secure HMAC function and novel key sharing scheme employing probabilistic
random key distribution which allows an OBU to update its compromised keys even
if it previously missed some revocation messages.
5. EXISTING SYSTEM
•
In VANETs, the primary security requirements are identified as entity
authentication, message integrity, non-repudiation, and privacy preservation.
•
A well-recognized solution to secure VANETs is to deploy Public Key
Infrastructure (PKI), and to use Certificate Revocation Lists (CRLs) for managing
the revoked certificates.
•
In PKI, each entity in the network holds an authentic certificate, and every message
should be digitally signed before its transmission
6. DEMERITS
Variety of attacks such as injecting false information
Modifying and replaying the disseminated messages can be easily launched.
A security attack on legitimate users.
The scale of VANET is very large.
7. Cont…
•
A CRL, usually issued by a Trusted Authority (TA), is a list containing all the
revoked certificates.
•
In a PKI system, the authentication of any message is performed
by first
checking if the sender’s certificate is included in the current CRL,
•
Since the CRL size is expected to be very large, the delay of checking the
revocation status of a certificate included in a received message is expected to be
long.

18. PROPOSED SYSTEM
Expedite Message authentication protocol (EMAP) which replaces the
CRL checking process by an efficient revocation checking process
using a fast and secure HMAC function. EMAP is suitable not only for
VANETs but also for any network employing a PKI system.
To the best of our knowledge, this is the first solution to reduce the
authentication delay resulting from checking the CRL in VANETs.
19. MERITS
EMAP has the lowest computation complexity compared with the CRL checking
processes employing linear and binary search algorithms.
The number of messages that can be verified using EMAP within 300 msec is
greater than that using linear and binary CRL checking by 88.7 and 48.38
percent, respectively.
The proposed EMAP in authentication reduces the end-to-end delay compared with
that using either the linear or the binary CRL checking process.
21. Development of VANET architecture
The Vehicular Adhoc Network model consists of Trusted Authority (TA), Roadside
Units (RSUs), On-Board Units (OBUs).
Trusted Authority, which is responsible for providing certificates and distributing
secret keys to all OBUs in the network.
Roadside Units which are fixed Units distributed all over the network.
On-Board Units, which are embedded in vehicles. OBUs can communicate either
with other OBUs through V2V communications or with RSUs through V2I
communications
22.
23. Message Authentication
If an OBU want to communicate other OBU means it send an encrypted message
with a HMAC code using HMAC algorithm, it generate by using the sender id and
common secret key which knows all the unrevoked OBUs.
The receiver OBU also generates the HMAC code by using common secret key.
Whether the HMAC code is same means the receiver knows the sender OBU is an
authenticated OBU otherwise not process the message
