With increasing dependency on smart function of cars the need for constant update similar to phones has raised. This blog explains in brief OTA update for automotive ECU and secure way to do so

Le Bluetooth SIG, chargé du développement de cette norme de transmissions sans-fil, indique que la version 5.1 du protocole intégrera une nouvelle technologie baptisée “New Direction Finding”. En combinant la triangulation avec l’analyse de l’angle du signal, il serait ainsi possible d’obtenir une géolocalisation de l’ordre du centimètre, et non du mètre comme auparavant.

Connected cars and electric vehicles are the way of the future with various governments declaring their target to completely adopt an electric transportation strategy. Global sales of electric cars accelerated fast in 2020, rising by 43% to more than 3 million, despite overall car sales slumping by a fifth during the coronavirus pandemic. The growth in the sector is also fuelled by the evolving ecosystem where new start-ups are innovating to bring to market new solutions.

As vehicle manufacturers increase the number of models within their vehicle fleets that are a) connected and b) carrying more data gathering capabilities from a range of different sensor types, one should expect that the data volumes that the manufacturers will gather will increase. In addition, new features and functionality will be added that will make use of network connectivity.

We present a turnover based adaptive HELLO protocol (TAP), which enables nodes in mobile networks to dynamically adjust their HELLO messages frequency depending on the current speed of nodes. To the best of our knowledge, all existing solutions are based on specific assumptions (e.g., slotted networks) and/or require specific hardware (e.g., GPS) for speed evaluation. One of the key aspects of our solution is that no additional hardware is required since it does not need this speed information.

Most entrepreneurs in the self-driving car space, said Gerryts, are focused on mobility. However, Oaken is focused on the layers and support systems that could underlie this operation.
To the startup, these edges of the industry could use smart contracts running on a blockchain to connect everything. Plus, cars equipped with a repository of cryptocurrency could purchase services – say, a tune-up or an oil change – using an instantaneous and inexpensive payment rail.

We propose the utilization of Elliptic Curve Cryptography in the design of an efficient data encryption/decryption system for sensor nodes in a wireless network. Elliptic Curve Cryptography can provide impressive levels of security standards while keeping down the cost of certain issues, primarily storage space. Sensors will benefit from having to store relatively smaller keys coupled with increased computational capability and this will be a stronger design as the bit-level security is improved. Thus, reducing the time delay between the nodes and to provide better results between them we have made use of this method. The implementation of this work is done with NS2 software.

Today’s warfighters and first responders, alike, must always be ready to mobilize, communicate, and operate under any conditions they may encounter. To be fully prepared for these dynamic environments, they must first have the necessary tactical knowledge and skillset.

Digital transformation and modernization initiatives are pervasive across all levels and sectors of our government – from federal civilian agencies, to military organizations, to state and local law enforcement and public safety organizations. Every agency and organization is exploring how new technologies can be implemented within the enterprise to increase efficiency, improve processes, and make operations better and more streamlined.

Prediction 8: Investors are more concerned about R&D, technology, FOTA. The most important components of new energy vehicles are motor, electric control, battery, and intelligent experience, and the amount of investment in R&D will directly affect the future of car companies. The more car companies invest in R&D, the more patents and achievements they can obtain, which is also more conducive to their future sustainable development. New car makers are choosing the pure electric route, and old traditional car companies are iterating engine technology while starting the electrification transformation. In terms of sales concentration, the market share of the top 15 in China has reached 77.5 percent. Compared to 2019, the top 15 car companies in 2020 have also increased their sales share of the overall market by 3 percentage points.

Carrying out software updates on our smartphones is a process we are all familiar with nowadays. On one hand, we expect the manufacturers to keep their operating systems up to date. On the other hand, we expect the same from app developers with regard to their apps. What’s more, the process of updating a software should be easy and, at best, require a simple tap of a button. So, why should this be any different when it comes to IoT devices? Let’s take a look at what over-the-air software updates in the IoT are all about.

吉利星瑞发布首次FOTA升级 打造“OTA生态计划”! 据介绍，“OTA”即空中下载技术，通过网络自动下载升级包、自动升级，经移动通信的接口实现对软件进行远程管理，实现现有功能/性能优化(BUG修复)、新功能推送等，通常多应用于手机、电脑等电子产品上。随着汽车新四化的推进和互联网大数据的快速发展，OTA技术也逐渐渗透到汽车行业，成为汽车高度智能化的必然趋势，开启了汽车不断成长的“生命通道”。汽车OTA又分为SOTA和FOTA两个不同“段位”。SOTA通常指软件升级，比如车载导航、娱乐应用、人机交互等车机功能，可以理解为手机里APP的更新。而FOTA则是指系统固件更新，可实现包括底盘悬挂、辅助驾驶、车身控制、信息娱乐等整车系统级别功能的全面更新。

Updating software and firmware using Over-the-Air (OTA) has increased in the handheld devices, industrial, and automotive sectors for the embedded platform with time. Once the product is in the real world, firmware or the software update related to bug fixes, security fixes, or the feature update is required for the betterment of the device and keeping it updated with latest software.

The CAR 2 CAR Communication Consortium (C2C-CC) aims at assisting towards accident free traffic (vision zero) at the earliest possible date. It further aims at supporting the highest safety level at improved traffic efficiency anywhere, anytime at the lowest cost to the end user and the environment. While working on solutions supporting all driving levels from manual to fully automated it considers specific needs of stakeholders, types of vehicles and users. The C2C-CC contributes to the development and specification of robust and reliable solutions that allow for a continuous and seamless evolution of required functionalities.

As vehicles become more and more software driven, the stakeholders of the automotive industry confront a new challenge. The challenge to manage and update the vehicle ECU software in order to mitigate any potential security attacks or functional failures. It is here that the role of FOTA a.k.a Firmware Over The Air gains prominence. Across the industries, FOTA is identified as a remote software-management technology for embedded systems, that enables a wireless firmware upgrade on a device.

Connected vehicles are considered to be one of the major drivers for investment in cellular communications technologies with forecasts projecting every new vehicle produced being ‘connected’ by 2025. What does this mean with respect to the impact on communications networks? What are the applications driving the growth in data and what data volumes will network operators be expected to transport?

The volumes of data being transmitted to and from Connected vehicles will rise rapidly with global production approaching 25 million new vehicles per year and all vehicle forecast to be ‘connected’ by 2025. With such vehicles being sold world-wide, the impact of communication networks will be seen in all of the major markets.

Ce projet de chaire, développé à l’ENSEIRB-MATMECA – Bordeaux INP, en synergie avec l’université de Bordeaux, s’inscrit dans des enjeux à la fois technologiques et territoriaux et fait écho aux nouveaux modes de mobilité urbaine. La question de la mobilité et des transports intelligents prend une importance croissante, en particulier, lorsque l’on évoque le développement territorial, d’un point de vue économique mais également humain. La thématique de la mobilité et des transports intelligents, ainsi que les usages et applications qui en découlent, est identifiée comme vecteur de croissance transverse à plusieurs domaines : le développement durable, la cohésion sociale et territoriale, le développement économique des territoires ainsi que la fluidification du trafic. A titre d’exemple, 30 % de la circulation dans la ville de Bordeaux concerne des véhicules qui cherchent des places de parking.

A wormhole attack is a type of attack on the network layer which reflects the issue of routing protocols. The classification is performed with several methods of machine learning consisting of K-Nearest Neighbor (KNN), Support Vector Machine (SVM), Decision Tree (DT), Linear Discrimination Analysis (LDA), Naive Bayes (NB), and Convolutional neural network (CNN). Moreover, for feature extraction, we used the properties of nodes, especially nodes speed in the MANET. We have collected 3997 distinct (normal 3781 and malicious 216) samples that comprise normal and malicious samples. Results of the classification show that the accuracy of KNN, SVM, DT, LDA, NB, and CNN methods are 97.1%, 98.2%, 98.9%, 95.2%, 94.7%, and 96.4%, respectively. Based on our findings, the DT method's accuracy is 98.9% and higher than other methods. In the next priority, SVM, KNN, CNN, LDA, and NB indicate high accuracy, respectively.
