Presentation Transcript

  1. Intruduction of the ExternalDomain

  2. Agenda • NCTS domains technically • External Domain schema and components • Usage of electronic signature, authorizations • ECC GW, ECC Envelope, communication

  3. NCTS domains from technical point of view

  4. NCTS context • First of Electronic Customs initiative projects • Fully electronic, paperless environment • Data evidence -> control system • Later ECS/AES, ICS/AIS, EMCS… • Trans-European on-line, distributed system • “Assisted” communication between traders • Authorized consignor, consignee • Key role of trader’s SW!

  5. Domain model • Proper architecture respecting division of responsibilities • Common Domain (DG TAXUD, CCN/CSI) • National Domain (CAS, Intranet) • External Domain (CAS, Internet) • Clear separation using gateways • CCN/CSI GW (DG TAXUD) • ECC GW (CAS)

  6. Domain communications • Using asynchronous messaging • Structured data format (UN-EDIFACT, XML) • Communication scenarios • Security

  7. External Domain Schema and Components

  8. External Domain Schema • ECC GW • Public Web client(s) • Reference data publication • AMS • Traders: • Web client • 3rd party SW • ERP integration

  9. Expected communication domains • NCTS • Transit business • GMS • Guarantee business • ECCGW • Communications • AMS • Certificatemanagement

  10. Using of Electronic Signature, Authorizations

  11. Electronic signature • For A&A • For data consistency • For non-repudiation • Must follow Serbian law • Traders – mainly personal certificates • CAS – server certificate (autonomous functionality of the system) • At ECC Envelope level (will be later)

  12. Electronic documents • Proper signature validation • especially at ECC GW • Proper archiving, LTP • (XAdES-X-L, restamping) • “Education” of traders

  13. Communication Authorizations (AMS) • Allows full electronic communication • Legal consequences • Data understanding, validity of certificates, rules • CommunicationAuthorizationID • Trader ID • Communication domain • List of personal IDs/certificates of authorized persons

  14. Simplified Procedures Authorizations (AMS) • Business oriented • Goods, places, seals • Other business and legal conditions • Managed by CAS • Base for automated procedures

  15. ECC GW, ECC Envelope, Communications

  16. Electronic Customs Clearance Gateway • Separation of ED and ND • Common services for NCTS and future systems • Communication (both directions, scenarios) • Security (electronic signatures, AMS relation) • Archiving • Logging & monitoring

  17. ECC Envelope • Common XML data structure • Business message communication carrier • Base for • A&A (electronic signature) • Routing (Participants, CAId) • Correlation (ScenarioID) • Monitoring (i.e. AppID, AppVersion)

  18. Communication Protocol • Web services (HTTPs, SOAP, WSDL) • XML, Unicode data • Send messages to CAS • Receive messages from CAS • Regular polling of messages • May contain additional services (polling frequency, unavailability, monitoring, …)

  19. Final Q&A

  20. Thank you very much for your attention
