Agenda• NCTS domains technically• External Domain schema and

components• Usage of electronic signature,

authorizations• ECC GW, ECC Envelope,

communication

SER/RS

NCTS domains from technical point of view


European Union


SER/RS

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!


European Union


SER/RS

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)


European Union


SER/RS

Domain communications• Using asynchronous messaging• Structured data format (UN-EDIFACT,

XML)• Communication scenarios• Security


European Union


SER/RS

External Domain Schema and Components


European Union


SER/RS

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


European Union


SER/RS

Expected communication domains• NCTS– Transit business

• GMS– Guarantee business

• ECCGW– Communications

• AMS– Certificate management


European Union


SER/RS

Using of Electronic Signature, Authorizations


European Union


SER/RS

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)


European Union


SER/RS

Electronic documents• Proper signature validation – especially at ECC GW

• Proper archiving, LTP – (XAdES-X-L, restamping)

• “Education” of traders


European Union


SER/RS

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


European Union


SER/RS

Simplified Procedures Authorizations (AMS)• Business oriented– Goods, places, seals– Other business and legal conditions

• Managed by CAS• Base for automated procedures


European Union


SER/RS

ECC GW, ECC Envelope, Communications


European Union


SER/RS

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


European Union


SER/RS

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)


European Union


SER/RS

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, …)
