In accordance with the Dematerialised Securities Act, KDD maintains the central registry, which the Act defines as the central information data base where the rights arising from dematerialised securities, individual holders of such rights and eventual third-party rights on securities are recorded. KDD ensures access to these data to all participants in the securities market through the basic transaction data base, for subsidiary records through WebServices, and for issuers requirements through protected KDD's web pages.

KDD's computer network ensures the access to information and its confidentiality and completeness to participants in the securities market. Communications between KDD and market participants are carried out through encripted connections. Our communications are based on TCP/IP communication protocol, our payment operations system uses the SWIFT protocol. 

Users of KDD services are provided with interactive access to the required information and data bases in CRVP system through modern internet technologies by using either the CLIENT application, designed for this purpose, or by WebServices. Access to data, provided to KDD users, is protected with PKI Technology.

Our technology mainly follows the challenges arising from the development of internet technology. We endeavour to successfully apply them in achieving the following principal business goals of KDD: 

• to ensure on-line exchange of data from the central registry with participants in the securities market,
• to apply the standards of data exchange,
• to follow developments in communication and information technology,
• to maintain the access to, completeness and confidentiality of information related to dematerialised securities. 

KDD ensures equal access to its services to all participants in the securities market by using standard computer and telecommunication equipment.

To protect the operation of the KDD information system systemic tools of various manufacturers are used. Protection of the KDD network and workstations of employees is ensured by the fire wall technology, anti-virus protection and equipment for active monitoring of fraudulent internet and intranet transactions. Business premises are under 24 hour security surveillance. Access to business premises is controlled by a central surveillance system. Entry to KDD offices is only possible by use of magnetic cards. These ensure the entry to employees during working hours. A fire emergency response plan is adapted to the building in which the KDD offices are located.

The applied technology adheres to international guidelines which have been drawn up for the securities market:

• use of the standards ISO 15022 and ISO 20022 for data exchange among participants in the securities market,
• use of XML message system for description of data,
• introduction of digital signature as a mechanism preventing a denial of electronic transaction,
• use of SWIFT for the part of KDD information system used for payment operations,
• use of standard ISO17799 for risk management and adequate protection of information.
