Getting a grip on AWD efficiency The safety and performance benefits of all-wheel drive are undeniable, but so are the penalties of added weight, friction losses, and complexity. Clever axle disconnects and E-axles are driving future AWD developments. E pluribus unum Inputs from many sensors are being combined to give safety systems a true vision of vehicle surroundings, with the resulting sensor fusion becoming a mainstay of autonomous vehicle electronics. Lightweighting poses repair challenges Mass-produced aluminum bodies and mixed-material structures present challenges for assembly and repair, as automakers increasingly pursue these lightweight strategies. Setting the standard Meggitt CTO Emeritus begins term at helm of SAE International, seeks to encourage cross-sector relations, elevate image of SAE as aerospace industry leader.

UAS Behaviour and Consistency Monitoring System for Countering Cyber Security Threats

2014-09-16
2014-01-2131
Upon their arrival, Unmanned Autonomous Systems (UAS) brought with them many benefits for those involved in a military campaign. They can use such systems to reconnoiter dangerous areas, provide 24-hr aerial security surveillance for force protection purposes or even attack enemy targets all the while avoiding friendly human losses in the process. Unfortunately, these platforms also carry the inherent risk of being built on innately vulnerable cybernetic systems. From software which can be tampered with to either steal data, damage or even outright steal the aircraft, to the data networks used for communications which can be jammed or even eavesdropped on to gain access to sensible information. All this has the potential to turn the benefits of UAS into liabilities and although the last decade has seen great advances in the development of protection and countermeasures against the described threats and beyond the risk still endures.

Implementation Guide for Data Management

GEIAHB859A
The federal government and industry have moved to concurrent acquisition and development processes using integrated process teams (IPTs). These processes are supported by timely, accurate, cross functional access to data within an integrated data environment (IDE) enabled by advances in information technology (IT). Since the advent of acquisition reform in 1994, Data Management (DM) practices have evolved from being directed by a prescriptive set of standards and procedures to use of the guidance in a principles-based standard -- ANSI/EIA 859.

GEIA Handbook 859 provides implementation guidance for ANSI/EIA 859, with discussions of applications of the standard's principles, tools, examples, and case studies. Handbook 859 is organized according to the lifecycle of data management and covers activities from the pre-RFP stage through records disposition.

Securing Connected Vehicles End to End

2014-04-01

As vehicles become increasingly connected with the external world, they face a growing range of security vulnerabilities. Researchers, hobbyists, and hackers have compromised security keys used by vehicles' electronic control units (ECUs), modified ECU software, and hacked wireless transmissions from vehicle key fobs and tire monitoring sensors. Malware can infect vehicles through Internet connectivity, onboard diagnostic interfaces, devices tethered wirelessly or physically to the vehicle, malware-infected aftermarket devices or spare parts, and onboard Wi-Fi hotspot. Once vehicles are interconnected, compromised vehicles can also be used to attack the connected transportation system and other vehicles. Securing connected vehicles impose a range of unique new challenges. This paper describes some of these unique challenges and presents an end-to-end cloud-assisted connected vehicle security framework that can address these challenges.

GUIDANCE FOR USAGE OF DIGITAL CERTIFICATES

2013-12-12
CURRENT
ARINC842-1
Newer generations of aircraft in production and use today are equipped with security applications that rely on digital certificates. It is expected that future aircraft will use certificates for increasing numbers of applications. The purpose of this document is to provide guidance for key life-cycle management, which refers to the phases through which digital certificates and associated cryptographic keys progress, from creation through usage to retirement. The guidance is based on open international standards that are adapted to the aviation environment, recognizing that a typical commercial airplane has a long lifespan, its operational environment is highly complex and regulated, and multiple stakeholders operate ground-based systems that communicate with airplanes. Using a standardized and consistent key management approach, as proposed in this document, helps to reduce cost of design, implementation, and operation even across a heterogeneous fleet.

Threat Analysis and Risk Assessment in Automotive Cyber Security

2013-04-08
2013-01-1415
The process of hazard analysis and risk assessment (H&R or HARA) is well-established in standards and methods for functional safety, such as the automotive functional safety standard ISO 26262. Considering the parallel discipline of cyber security, it is necessary to establish an analogous process of threat analysis and risk assessment (T&R) in order to identify potential security attacks and the risk associated with these attacks if they were successful. While functional safety H&R processes could be used for threat analysis, these methods need extension and adaptation to the cyber security domain. This paper describes how such a method has been developed based on the approach described in ISO 26262 and the related MISRA Safety Analysis Guidelines. In particular key differences are described in the understanding of the severity of a security attack, and the factors that contribute to the probability of a successful attack.

Advancing Aircraft Cyber Security - Potential New Architectures and Technologies

2012-03-16
Cyber security in the aviation industry, especially in relation to onboard aircraft systems, presents unique challenges in its implementation and management. The cyber threat model is constantly evolving and will continually present new and different challenges to the aircraft operator in responding to new cyber threats without either invoking a lengthy software update and re-certification process or limiting aircraft-to-ground communications to the threatened system or systems. This presentation discusses a number of system architectural options and developing technologies that could be considered to enhance the aircraft cyber protection and defensive capabilities of onboard systems as well as to minimize the effort associated with certification/re-certification. Some of these limit the aircraft?s vulnerabilities or in cyber terms, its ?threat surface?.

This paper is the second in the series of documents designed to record the progress of a series of SAE documents - SAE J2836™, J2847, J2931, & J2953 - within the Plug-In Electric Vehicle (PEV) Communication Task Force. This follows the initial paper number 2010-01-0837, and continues with the test and modeling of the various PLC types for utility programs described in J2836/1™ & J2847/1. This also extends the communication to an off-board charger, described in J2836/2™ & J2847/2 and includes reverse energy flow described in J2836/3™ and J2847/3. The initial versions of J2836/1™ and J2847/1 were published early 2010. J2847/1 has now been re-opened to include updates from comments from the National Institute of Standards Technology (NIST) Smart Grid Interoperability Panel (SGIP), Smart Grid Architectural Committee (SGAC) and Cyber Security Working Group committee (SCWG).
