Vendor registration

Each Local CMS needs a vendor registration at RI. The correct vendor must be known and registered in RI for the clubs using the service. In order to separate the SEMDA services, one vendor is defined for each Local CMS. The corresponding vendor names using SEMDA service are:

  • SEMDA - CH&FL - Polaris
  • SEMDA - AT&BIH - Polaris
  • SEMDA - BE&LUX - Polaris
  • SEMDA - FR - Polaris
  • SEMDA - SE - Polaris
  • SEMDA - IS - Polaris
  • SEMDA - ES - Polaris
  • SEMDA - DE - RoCas
  • SEMDA - DE - Aurora
  • SEMDA - NL
  • SEMDA - FI
  • SEMDA - IT - 2032
  • SEMDA - IT - 2041/42

For new customers having a new Local CMS using SEMDA, RCS will request RI to create a new vendor.

Authorization

The authorization to use the SEMDA systems is issued by the RCS. Respective product contract and SLA must be signed. RCS will then pass the required unique authentication key to the Local CMS. This key must be used for the connection to SEMDA and in all requests.

Authentication

Each request from Local CMS to SEMDA must contain a unique authentication key which identifies the Local CMS. This authentication key is created by the RCS and passed to the Local CMS after contract and SLA have been signed. Request without valid authentication key are discarded.

Access and encryption

Access to SEMDA is possible only through https protocol.

All data in transfer between Local CMS and SEMDA and between SEMDA and RI is encrypted.

Data Security

SEMDA does not have persistent storage like a database. It uses a reliable message broker (RabbitMQ) to temporarily store requests from various Local CMS. The requests are managed in a queue, assigned to each particular Local CMS. The request data is automatically destroyed when a request has been processed. The reliability feature of RabbitMQ ensures that the system survives a power failure or software crash without loss of data.

The access to the request data is possible only through the programmatic components of SEMDA. There is no GUI or tool to display the request data available to the SEMDA customers.

SEMDA fulfills the highest security requirements because:

  1. No data is persistently stored in SEMDA
  2. No data is exposed to a user interface or an interactive tool.
  3. Data related to a particular Local CMS is separated and isolated from all other connected systems.
  4. The data exchanged between the particular Local CMS and RI is not passed to any other system.
