The ENX Association (formerly: European Network Exchange Association ) is an amalgamation of European automobile manufacturers, suppliers and associations.
The ENX Association, founded in 2000 under the auspices of the Verband der Automobilindustrie with its headquarters in Boulogne-Billancourt (France) and Frankfurt am Main, is an association under French law. The 16 members of the association, who are all represented on the so-called ENX Board, are Audi , BMW , Bosch , Continental , Daimler , DGA, Ford , Magna , PSA Peugeot Citroën , Renault , Volkswagen as well as the automobile associations ANFAC (Spain), GALIA (France), SMMT (UK) and VDA (Germany). Upon request, the association can decide on the admission of additional members, but according to the association's information, the total number of members is limited by the statutes.
Fields of activity
The ENX Association is a non-profit organization and acts as the legal and organizational umbrella for the ENX network standard. It offers the participating companies a platform for the exchange of information and for the initiation of pre-competitive cooperation projects in the field of information technology. The main driving force behind the creation of the standard by the German and French industries was the protection of intellectual property while reducing costs and complexity in the automotive data exchange.
The advantage of creating a “Trusted Community” for branches of industry is cited that although companies protect their own infrastructure, they reach their limits when encryption or authentication solutions are to be used across companies and recognized as trustworthy by one another. At the latest when both sides strive to implement their own mechanisms, this too often ends in a dead end. This can be seen in the example of email encryption, when security rules collide with regard to shared application use and thousands of unencrypted data connections. A common trustworthy infrastructure can help here. Ford cites the use of ENX for communication with suppliers as an example of how considerable savings can be achieved through consolidation and standardization.
In the antitrust assessment of the joint eBusiness purchasing platform of DaimlerChrysler, Ford Motor Company, General Motors and Renault / Nissan (Covisint) by the German Federal Cartel Office, importance was attached to the possibility of using the ENX, which is open to all automotive suppliers, as an access channel.
Another area of activity is the implementation of industrial requirements for cross-company IT security. Subject areas are described here
- Secure e-mail (cross-company)
- Secure cloud computing (cross-company)
- Protection of intellectual property in development cooperation (e.g. using Enterprise Rights Management, ERM)
The ENX Association is a member of the ERM.open project of ProSTEP iViP e. V. and was already active in the previous SP2 project together with Adobe, BMW, Augsburg University of Applied Sciences, Continental, Daimler Fraunhofer IGD, Microsoft, PROSTEP, Siemens PLM, TU Darmstadt, TAC, Volkswagen and ZF Friedrichshafen.
The SkIdentity project, in which the ENX Association is involved, was announced on March 1, 2011 at the CeBIT IT trade fair in Hanover by the Federal Ministry of Economics and Technology (BMWi) as one of the 12 winners of the BMWi technology competition “Secure Cloud Computing for SMEs and the Public Sector - Trusted Cloud ”announced. With the Trusted Cloud program, the BMWi wants to promote “the development and testing of innovative, secure and legally compliant cloud solutions”.

Use of the ENX network
The communication network of the same name for the European automotive industry is based on the standards set by the ENX Association in terms of security, availability and interoperability. The so-called industry network ensures the secure exchange of development, production control and logistics data in the European automotive industry.
The automotive industry is characterized by strong international cooperation and the need to coordinate closely interlinked processes across companies that require precise coordination and seamless data exchange between the partners. This makes “integrated global network concepts” necessary. ENX is described as a platform that creates the conditions for such cooperative production models.
A realignment began at the end of 2002. The aim was to consistently align the technical further development to the requirements of the users, especially small and medium-sized companies. The implementation took several years. In June 2004 French users still complained about the lack of inexpensive entry-level solutions in France Telecom's portfolio.
As of March 2013, over 1,500 companies in the automotive industry and other sectors in over 36 countries are using the worldwide network.
The network can be used for all IP-compatible protocols and applications. The bandwidth ranges from classic EDI data exchange to access to databases and secure e-mail exchange to the implementation of video conferences. The use of EDI transmission protocols such as OFTP (Odette File Transfer Protocol), OFTP2 and AS2 in the ENX network is widespread. OFTP2, which was developed in 2004, also enables use via the public Internet.
According to the trade press, individual automobile manufacturers have been demanding the use of OFTP2 via the Internet since 2010. Affected are "several 10,000 suppliers". In this medium, which is accessible to everyone, significantly more security efforts have to be made when transferring sensitive data, and the conversion and implementation costs are difficult to estimate.
Use by automobile manufacturers
The following table shows which car manufacturers have an ENX connector.
Not connected to the ENX network are those owned by Zhejiang Geely Holding Group Company Ltd. (People's Republic of China) located Volvo Cars AB and Saab Automobile AB, in which since 2011 with the Pang Da Automobile Trade Co. Ltd. and the Youngman Lotus Automobile two companies from the People's Republic of China are significantly involved.
Use by TOP 100 automotive suppliers worldwide
The user data published on the Internet shows that 85 of the 100 largest automotive suppliers are listed on ENX and 9 of the remaining 15 are connected to the Japanese automotive network JNX. The latter are companies headquartered in Japan.
Registration as a prerequisite for use
Registration by the ENX Association is a prerequisite for using the ENX network. Registration can be requested directly from the ENX Association or one of its representatives.
Representations of the ENX Association
The ENX is represented in some countries or sectors by industry associations and organizations (so-called ENX Business Centers). These organizations serve the users u. a. as a contact in the respective national language, processing registration applications and responsible for the initial authorization of new users in their respective area of representation.
With this representation model, the ENX Association wants to enable industry associations and similar organizations to independently manage user groups.
Operation of the ENX network
Operation of the network and connections
Operation by certified service providers
The ENX network fulfills quality and security features that can be found in the company's own networks , and at the same time is as open and flexible as the public Internet for the participating automobile manufacturers , suppliers and their development partners . The data exchange between ENX users takes place via an encrypted Virtual Private Network (VPN) via the networks of the communication service providers that have been certified for this by the ENX Association.
The first certified communications service provider was France Télécom (now Orange). It was signed on December 21, 2001. This was followed by Deutsche Telekom subsidiary DeTeSystem, Telefonica, Infonet and, in 2007, Verizon Business. In 2010, with ANXeBusiness, Business Communication Company (at that time under the name BCC and now incorporated into EWE Tel ) and Türk Telekom, three other companies successfully underwent ENX certification. Open Systems AG followed as the youngest provider in 2011.
The offers of the certified providers are interoperable and are provided in competition.
Overview of the service providers certified according to the ENX standard
According to the ENX Association, certification takes place in a two-stage process. In the first step, the so-called concept phase, the ENX Association checks whether the ENX operating model of the provider corresponds to the technical ENX specifications. In the second step, the provider implements its operating model. In addition to the internal organization, this includes checking IPSec interoperability in the so-called "ENX IPSec Lab", implementing ENX encryption and connecting to the already certified providers via private peering points, so-called "ENX Points of Interconnection". Finally, the implementation and compliance with the ENX specifications is checked in a pilot test. With appropriate preparation by the provider, it should be possible to carry out the fee-based certification within about three to four months.
Central operational components in the background
On behalf of and under the control of the ENX Association, central services are provided that simplify the connection ("interconnectivity") of the individual certified service providers and the interoperability of the encryption hardware used. These include the so-called Points of Interconnection (“ENX POIs”), the IPSec interoperability laboratory (“ENX IPSec Lab”) and the company's own public key infrastructure (“ENX PKI”) in the ENX Trust Center.
The points of interconnection have a geographically redundant structure, are interconnected and are operated in data centers in the following regions
- Rhine-Main area, Germany
- Isle-de-France, France
- United States East Coast
These central operational components are not visible to the individual user. The customer only obtains his own connection including IP router, encryption hardware, key material, uninterrupted end-to-end encryption of every communication relationship and individual service level agreements directly from the selected certified telecommunications service provider.
Industry network JNX and the ANXeBusiness in North America
An industry network that is technically and organizationally similar to ENX also exists in the Japanese automotive industry with the Japanese Network Exchange (JNX). The control is exercised by the JNX Center, which is linked to the Japanese automotive associations JAMA and JAPIA. JNX and ENX are not connected.
In contrast, there are significant technical, organizational and commercial differences between the ENX standard and the American ANX, which was developed in the 1990s.
Connection between Europe and North America
ENX as a common standard since 2010
On April 26, 2010, the ENX Association and ANX eBusiness announced that they would be joining their networks to create a global standard in the automotive industry. The connection creates a transatlantic industrial network with more than 1500 affiliated companies. Effective operation began when the pilot phase was completed on May 26, 2010.
According to consistent statements from the ENX Association and the ANX eBusiness Corp. only the ENX standard is used for transatlantic connections both in Europe and in North America. ANX and ENX describe the interconnection in their publications as free of charge for the individual user.
Differences between ENX and ANX
The network for North America, the so-called Automotive Network Exchange (ANX), is operated by ANXeBusiness Corp. operated. Originally also initiated by the automotive industry and operated by a consortium, in contrast to ENX, it was sold and subsequently operated as a classic service company with the intention of making a profit.
ANX is a physical network where availability is paramount. ANX is consistently based initially on the operation of leased lines with high availability guarantees. With the additional product "TunnelZ", ANX also offers an optional VPN tunnel management system that is not used by all connected manufacturers and suppliers. In the classic ANX network, key management takes place using a pre-shared key (PSK); the encryption strength is limited to DES.
ENX is designed as a managed security service in which uniform tunnel management, a trust center-based public key infrastructure (PKI) and authentication and encryption mechanisms based on different networks (from private to public) are used throughout.
In fact, there is a single provider to customers in the ANX network, the company ANXeBusiness itself, while ENX services are offered by various competing companies.
In order to connect the networks anyway, ANXeBusiness continues to operate its own network logically separated from ENX and untouched, but provides every ANX user who wishes to do so via their own physical network with a native ENX connection including all required security and service features. For this purpose, ANX has undergone certification and monitoring by the ENX Association and acts as an ENX certified service provider.
With the certification of ANXeBusiness as an ENX provider, ENX and ANX use in particular the organizational differences described between non-profit industrial consortium (ENX) on the one hand and service provider (ANX) on the other to connect the two networks. We cannot speak of mutual interoperability, since ANX adopts the ENX standard. For ANX, the potential availability of all ENX users will presumably result in new market perspectives. At the same time, it can be assumed that the bridge into the ANX will facilitate the market entry of other ENX providers in the USA and thus create competition.
