Intruduction of the External Domain. Agenda NCTS domains technically External Domain schema and components Usage of electronic signature, authorizations ECC GW, ECC Envelope, communication. NCTS domains from technical point of view. NCTS context
E N D
Agenda • NCTS domains technically • External Domain schema and components • Usage of electronic signature, authorizations • ECC GW, ECC Envelope, communication
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!
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)
Domain communications • Using asynchronous messaging • Structured data format (UN-EDIFACT, XML) • Communication scenarios • Security
External Domain Schema • ECC GW • Public Web client(s) • Reference data publication • AMS • Traders: • Web client • 3rd party SW • ERP integration
Expected communication domains • NCTS • Transit business • GMS • Guarantee business • ECCGW • Communications • AMS • Certificatemanagement
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)
Electronic documents • Proper signature validation • especially at ECC GW • Proper archiving, LTP • (XAdES-X-L, restamping) • “Education” of traders
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
Simplified Procedures Authorizations (AMS) • Business oriented • Goods, places, seals • Other business and legal conditions • Managed by CAS • Base for automated procedures
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
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)
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, …)
