Working group description

Working Group Organisation

CNA activities take shape through the creation of task forces; the main working groups are:

• WG1:  improving and developing Calypso reference specification, to provide an appropriate solution to transport operator needs.

• WG2:  favouring interoperability between transport networks, and amongst networks, to ensure that any Calypso Portable Object can work with any Calypso terminal.

• WG3:  promoting Calypso technology worldwide and participating in national and international standardization initiatives so that Calypso’s good practices will spread throughout the community.

The technical working group WG1 welcomes all contributors who are willing to participate and bring their own expertise: operators, industry vendors and manufacturers, consultants, software houses, and so on.

Its main objective is to ensure a constant improvement of the security features of Calypso. The second objective is to set up and maintain a policy of certification for the different products used in Calypso systems. Another focus is to facilitate the emergence of new technologies and services in the Calypso environment by providing solutions to the world of transport.

The WG1 is organized around Working Packages according to the related topics. Each Package is managed by a company leader, chosen by CNA and paid accordingly.

An internet collaborative tool federates the Working Packages: http://www.cnawg.net.

Every CNA member can participate at different levels: from a simple following of the discussions on the dedicated forums, through a review of the draft documents of specification, and until a more active participation in the regular meetings (also available via web conference).

 

Main achievements

The goal of each working package, is to find a general agreement on a specification document before to submit it to the board of CNA for approval.

These documents are available for the CNA members.

 

Following main and recent achievements can be highlighted:

• The specification of a Calypso Light Application (CLAP), and its associated functional test plan.

• The specification of a Calypso HCE Application.

• The User Manual of the version 1.3 of the Calypso CNA applet, which aims at promoting Calypso on NFC phones.

• The last revision 3.2 of the Calypso Portable Object Specification, with AES crypto algorithm and new features for privacy data protection.

• The functional test plan for the Calypso Portable Object Certification that has been implemented for the technical evaluation of the portable object.

• The revision 2.7 of the Hoplink specification, which better takes account of NFC mobile phones and strengthen the security of Triangle, together with a new version of the document "Best Practices of Hoplink", which aims at facilitating the implementation of Hoplink in the equipments of a newly partner.
