History

The association

Founded in 2000 under the auspices of the Association of the Automotive Industry ENX Association based in Boulogne- Billancourt (France ) and Frankfurt am Main is an association under French law. The 16 members of the Association, all of which are also represented in the so-called ENX Board, are Audi, BMW, Bosch, Continental, Daimler, DGA, Ford, Magna, PSA Peugeot Citroën, Renault, Volkswagen and automotive associations ANFAC (Spain ), GALIA (France), SMMT (UK), OSD (Turkey) and VDA ( Germany ). At the request of the club can decide on the inclusion of other members, according to association data, the total number of members is limited but registered moderate.

Fields of activity

The ENX Association is a non-profit organization and act as a legal and organizational umbrella for the ENX network standard. It provides the participating companies with a platform to exchange information and to initiate pre-competitive cooperation projects in the field of information technology. Main drive of the German and French industry to the creation of standards was the protection of intellectual property, while reducing cost and complexity in the automotive data exchange.

The advantage of creating a " trusted community " for industries is argued that although companies protect their own infrastructure, but have their limitations when encryption or authentication solutions are to be used across the enterprise and mutually recognized as trustworthy. By the time both sides strove to enforce its own mechanisms, end this too frequently. At an impasse This shows the example of the e -mail encryption, in the collision of safety rules on common application usage and thousands of unencrypted data links. A common trust infrastructure creates a remedy. So Ford cites the use of ENX for communication with the suppliers as an example of how significant savings can be achieved through consolidation and standardization.

In the antitrust assessment of common e-business purchasing platform of the company Daimler Chrysler, Ford Motor Company, General Motors and Renault / Nissan ( Covisint ) by the Federal Cartel Office, was the ability to use the open for all automotive ENX as an access attached importance.

Another field of activity is the implementation of industrial requirements in the enterprise-wide IT security. Here are described as topics

• Secure e-mail ( across companies )
• Secure cloud computing ( across companies )
• Protection of intellectual property in the development cooperation ( eg by means of Enterprise Rights Management, ERM)

The ENX Association is a member of ERM.open project of the ProSTEP iViP eV and was already in collaboration with Adobe, BMW, FH Augsburg, Continental, Daimler Fraunhofer IGD, Microsoft, PROSTEP, Siemens PLM, TU Darmstadt, TAC, Volkswagen and ZF Friedrichshafen in the previous project SP2 project active.

The SkIdentity project on which the ENX Association is involved, was on 1 March 2011 at the IT fair CeBIT in Hanover by the Federal Ministry of Economics and Technology (BMWi ) " Secure as one of the 12 winners of the BMWi - technology competition Cloud Computing announced Trusted Cloud " - for SMEs and the public sector. The BMWi is to promote with the Trusted Cloud Program " to develop and test innovative, secure and legally compliant cloud solutions ."

Use of the ENX network

Usage scenarios

The same communication network of the European automotive industry is based on the set of the ENX Association standards in terms of safety, availability and interoperability. The so-called branch network ensures the secure exchange of design, production control and logistics data in the European automotive industry.

The automotive industry is characterized by strong international cooperation and the need for coordination across companies tightly linked processes 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 collaborative production models.

The end of 2002 a new direction was begun. The aim was to evaluate the technical development consistently align to the requirements of users, especially small and medium enterprises. The implementation took several years to complete. Complained yet in June 2004 French users the lack of affordable entry-level solutions in the portfolio of France Telecom.

As of March 2013 to use more than 1,500 companies in the automotive industry and other industries in over 36 countries globally available network.

The network can be used for all IP - appropriate protocols and applications. The spectrum ranges from the traditional EDI data exchange via access to databases and secure email exchange to implementation of video conferencing. The use of EDI transmission protocols such OFTP ( Odette File Transfer Protocol), OFTP2 and AS2 in the ENX network is widespread. Developed from 2004 OFTP2 allows use on the public Internet.

According to the trade press request separate automotive manufacturers since 2010 the use of OFTP2 over the Internet. Affected were " several 10,000 suppliers ". In this accessible for each medium significantly more security effort must be driven in the transfer of sensitive data, conversion and implementation costs are difficult to estimate.

Use by automotive manufacturers

The following table shows which have automotive industry and has a ENX.

Not connected to the ENX network are owned by Zhejiang Geely Holding Group Company Limited. ( PRC ) located Volvo Cars AB and Saab Automobile AB, at the since 2011 with Pang Da Automobile Trade Co. Ltd.. and Youngman Lotus Automobile, two companies from the People's Republic of China are significantly involved.

Use by TOP 100 automotive suppliers worldwide

The Internet users publish data can be inferred that 85 of the top 100 automotive suppliers in ENX are listed and are connected by the remaining 15 more 9 to the Japanese automotive network JNX. In the latter there are companies headquartered in Japan.

Registration as a condition of use

Requirement for the use of the ENX network is a registration by the ENX Association. Registration can be applied directly to the ENX Association or any of its representatives.

Representations of the ENX Association

The ENX in some countries or sectors through industry associations and organizations represented (so-called ENX Business Center). These organizations serve the users, inter alia, as a partner in the local language, edit registration applications and be responsible for the initial authorization of new users within their respective area of ​​representation.

With this representation model, the ENX Association will enable industry associations and similar organizations an independent self- management of user groups.

Operation of the ENX network

Operating the network and the connections

Operation by certified service providers

The ENX network meets quality and safety features, such as those found in company networks and at the same time as open and flexible as the public Internet for the participating automotive manufacturers, suppliers and development partners. The data exchange between ENX users find means of an encrypted Virtual Private Network ( VPN) over the networks of communication service providers that have been certified by the ENX Association for this purpose.

The first certified service provider communication was the German Telekom subsidiary DeTeSystem. First, followed by Orange, Telefonica, Infonet and in 2007 Verizon Business. In 2010, three other companies have successfully undergone the ENX certification with ANXeBusiness, BCC and Türk Telekom. As the youngest provider Open Systems AG followed in 2011.

The offers of certified vendors are interoperable and are provided in competition.

Overview certified by ENX standard service

Certification process

According to the ENX Association certification is carried out in a two step process. In the first step, the so-called concept phase, the ENX Association verifies whether the ENX operating model of the provider complies with the technical specifications ENX. In the second step, the provider implements its operating model. In addition to the internal organization should include the examination of the IPSec interoperability in the " ENX IPSec Lab", the implementation of the ENX encryption and connection to the already certified provider via private peering points, so-called "ENX Points of Interconnection ." Finally, the implementation and compliance with the ENX specifications in a pilot test is checked. With appropriate preparation by the seller, it should be possible to carry out the paid certification within about three to four months.

Central plant ingredients in the background

On behalf of and under the control of ENX Association central services are provided that serve a simplified connection (" interconnectivity " ) of each certified service and interoperability of cryptographic hardware used. These include the so-called Points of Interconnection ( " POI ENX " s ), the IPSec Interoperability Lab (" ENX IPSec Lab" ) and its own Public Key Infrastructure (" PKI ENX ") in the ENX Trust Center.

The points of interconnection are structured geographically redundant, interconnected and operated in data centers in the following regions

• Rhine -Main region, Germany
• Isle- de -France, France
• East Coast of the United States

These key operating components are not visible to the individual user. The customer refers only its own connection including IP routers, encryption hardware, key material, continuous end-to- end encryption of all communication relationship and individual service level agreements directly above the currently selected certified telecommunications provider.

Global availability

Industry network JNX and ANXeBusiness in North America

One of the ENX technically and organizationally similar industry networks exist with the Japanese Network Exchange ( JNX) in the Japanese automotive industry. The control is exercised by JNX Center, which is connected to the Japanese automobile associations JAMA and JAPIA. JNX and ENX are not connected.

On the other hand, there are significant technical, organizational and commercial differences between the ENX standard and the American ANX developed already in the 1990s.

Connection between Europe and North America

ENX as a common standard since 2010

On 26 April 2010, the ENX Association and ANX eBusiness have been known to connect their networks to create a global standard in the automotive industry. By combining created a transatlantic industrial network with more than 1,500 companies connected. The mode of operation was recorded with completion of the pilot phase on 26 May 2010.

It thereby comes through loud matching statements of the ENX Association and the ANX eBusiness Corp.. in transatlantic connections both in Europe and in North America exclusively for the ENX standard used. ANX and ENX designate the Interconnection free in their publications than for the individual user.

Differences between ENX and ANX

The Network for North America, called the Automotive Network Exchange ( ANX ), is of the ANXeBusiness Corp.. operated. Originally also initiated by the automotive industry and operated a consortium, was sold as opposed to ENX and operated in the episode as a classic service company with a profit motive.

ANX is a physical network, wherein the availability is paramount. Consistently ANX based first on the operation of solid compounds with high availability guarantees. ANX provides with the addition product " TunnelZ " in addition also an optional VPN tunnel management to, which is not used by all member manufacturers and suppliers. In the classical ANX network, the key management using pre-shared key ( PSK ) is carried out, the encryption strength is limited to DES.

ENX is designed as a managed security service, are used for the continuous uniform tunnel management, a trust center -based Public Key Infrastructure ( PKI) and authentication and encryption mechanisms based on different networks ( from private to public).

In fact, there are in the ANX network to customers a single vendor, the company ANXeBusiness itself while ENX services are offered by different, competing companies.

To connect the networks anyway, ANXeBusiness operates its own network logically separated from ENX and untouched on, but does from each ANX user who wishes to do so, required about one's own physical network with a native ENX connection including all security and service features. ANX has undergone for this purpose of certification and monitoring by the ENX Association and acts as ENX certified service provider.

Conclusion

With the certification of ANXeBusiness as ENX ENX and ANX providers use particular organizational differences described between non-profit industry consortium ( ENX ) on one side and the service provider ( ANX ) on the other side to connect the two networks. From mutual interoperability can not be said, as the ANX ENX adopts default. For ANX all ENX users arising from the potential accessibility probably new market perspectives. At the same time it can be assumed that the bridge facilitates market entry of other ENX provider in the U.S. to ANX, creating competition.
