Vehicle-to-everything (V2X) is the communication technology designed to support road safety for drivers and autonomous driving. The light-weight security solution is crucial to meet the real-time needs of on-board V2X applications. However, most of the recently proposed V2X security protocols—based on the Elliptic Curve Digital Signature Algorithm (ECDSA)—are not efficient enough to support fast processing and reduce the communication overhead between vehicles. ECDSA provides a high-security level at the cost of excessive communication and computation overhead, which motivates us to propose a light-weight message authentication and privacy preservation protocol for V2X communications. The proposed protocol achieves highly secure message authentication at a substantially lower cost by introducing a hash chain of secret keys for a Message Authentication Code (MAC). We implemented the proposed protocol using commercial V2X devices to prove its performance advantages over the standard and non-standard protocols. We constructed real V2X networks using commercial V2X devices that run our implemented protocol. Our extensive experiments with real networks demonstrate that the proposed protocol reduces the communication overhead by 6 times and computation overhead by more than 100 times compared with the IEEE1609.2 standard. Moreover, the proposed protocol reduces the communication overhead by 4 times and the computation overhead by up to 100 times compared with a non-standard security protocol, TESLA. The proposed protocol substantially reduces the average end-to-end delay to 2.5 ms, which is a 24- and 28-fold reduction, respectively, compared with the IEEE1609 and TESLA protocols.


The overhead for resource utilization in the round coding operation of security coding is large. Though lightweight protocols are used as a measure of provisioning, higher level of security in many real time applications, the need of key scheduling, key generation and s-box operation leads to large resource utilization. This resource consumption intern leads to large power consumption and area overhead. To minimize the resource utilization in this paper, a new resource optimization technique following resource reutilization scheme is proposed. The resource utilization is synchronized by the delay term instruction application in cryptography coding.


Due to constrained assets and adaptability, security protocol for Internet of Things (IoT) should be light-weighted. The cryptographic solutions are not possible to apply on little and low-power devices of IoT in view of their power and space impediments. In this paper, a light-weight protocol to verify the information and accomplishing information provenance is introduced for multi-hop IoT arrange. The Received Signal Strength Indicator (RSSI) of conveying IoT nodes are utilized to produce the connection fingerprints. The connection fingerprints are coordinated at the server to process the relationship coefficient. Higher the estimation of connection coefficient, higher the rates of verified information move. Lower worth gives the recognition of ill-disposed node in the middle of a particular connection. Information provenance has additionally been accomplished by examination of pocket header with all the accessible connection fingerprints at the server. The time unpredictability is processed at the node and server level, which is O(1). The power scattering is determined for IoT nodes and overall network. The outcomes demonstrate that the power utilization of the framework and time complexity. Exploratory outcomes show that up to 97% connection is accomplished when no attacker node is available in the IoT network.

Light weight materials which possess high strength and durability are being utilized by the automotive industry to increase fuel economy. Rapidly solidified (RS) Al alloys are currently being extensively studied for this purpose. In this investigation the microstructure of an extruded Al-8Fe-2Mo alloy, produced by Pratt & Whitney Aircraft, Goverment Products Div. was examined in a JE0L 2000FX AEM. Both electropolished thin sections, and extraction replicas were examined to characterize this material. The consolidation procedure for producing this material included a 9:1 extrusion at 340°C followed by a 16:1 extrusion at 400°C, utilizing RS powders which have also been characterized utilizing electron microscopy.

Abstract Current demands by the consumer, the automobile industry, and the environment have determined the basis of this investigation. In the past, the requirements—ever faster, ever sportier—were accepted as decisive parameters for the development of our study. In the future, rational and safety-related tire characteristics as well as environmental consciousness will increase, whereas purely performance-related parameters will diminish in their importance. Through our light-weight tire project, we have paved the way for future tire generations. The first priority is the minimal use of material resources; this means a reduction of materials and energy in tire production by using advanced design and production methods without sacrificing performance standards. This benefits the consumer—the final judge of all of our activities—by considerably reducing the rolling resistance, leading to lower fuel consumption. Further design targets include the improvement of rolling behavior and increased comfort by reducing tire weight, and therefore a reduction in unsprung masses on the vehicle.
