The strategic importance of applying the concept of digital certificates and its underdevelopment in electronic commerce of Serbia, points to the need of setting Theoretical support for its efficient development and implementation. In this sense, the subject of this dissertation is to improve the development and deployment of digital certificates, which are focused on building specific Public Key Infrastructure - PKI system, which should be designed to be efficient and flexible solution to light of different PKI requirements. Construction of an information system based on statistical analysis of the effectiveness of PKI and digital certificates. The analysis is to define the business needs of PKI in accordance with the development of electronic services, using modern methods for static evaluation. The main objectives are that, based on statistical methods and analysis of real data available from the process of PKI, it is possible to identify latent system parameters, which would be adequate identification and application of quality management processes contribute to the improvement of PKI digital certificates in electronic commerce and make the automation of key management processes PKI digital certificates of the selected system, using statistical methods, in order to integrate the appropriate statistical model. The experimental part of a doctoral dissertation relates to the application model, which is the use of digital certificates, which are defined activities that have a strategic role in promoting e-business, determining the degree of importance of activities and measuring its effectiveness. In this module, using applicative statistical analysis we came to the target architecture PKI system, which gave the best results in the practical application of modern business environments. For the development of digital certificates is critical information because they provide information on which users of electronic services, making more efficient and effective decisions and therefore increase the level of satisfaction with life.- U okviru ove doktorske disertacije, pod razvojem digitalnih sertifikata podrazumeva se uvođenje koncepta infrastrukture javnih ključeva PKI (PKI - Public Key Infrustructure) sistema, koje objedinjuje mnoštvo elemenata i pojava iz domena računarske statistike, informaciono – komunikacionih tehnologija i elektronskog poslovanja. Strateška važnost primene koncepta digitalnih sertifikata i njegova nedovoljna razvijenost u elektronskom poslovanju Republike Srbije,ukazuje na potrebu postavljanja teorijske podrške njegovog efikasnog razvoja i primene.U tom smislu,predmet istraživanja ove disertacije predstavlja unapređenje razvoja i uvođenja digitalnih sertifikata, koji su usmereni na izgradnju određene infrastrukture javnih ključeva - PKI sistema, koji treba da bude dizajniran tako da bude efikasan i fleksibilan u cilju lakog rešavanja različitih PKI zahteva. Izgradnja informacionog sistema bazira se na statističkoj analizi efikasnosti primene PKI sistema i digitalnih sertifikata. Osnovni ciljevi su da, na osnovu statističkih metoda i analize dostupnih realnih podataka iz procesa PKI sistema, je moguće prepoznati latentne parametre sistema, čija bi adekvatna identifikacija i primena kvalitativno doprinela poboljšanju procesa upravljanja digitalnim sertifikatima PKI sistema u elektronskom poslovanju i izvršiti automatizaciju ključnih procesa upravljanja digitalnim sertifikatima odabranog PKI sistema, putem statističkih metoda, sa ciljem da se objedine u odgovarajući statistički model. Eksperimentalni deo doktorske disertacije odnosi se na aplikacioni model, koji predstavlja primenu digitalnih sertifikata, gde su definisane aktivnosti koje imaju stratešku ulogu u unapređenju elektronskog poslovanja, određivanju stepena značaja aktivnosti i merenja efekta njegove primene. Na ovakvom aplikativno modulu uz primenu statističkih analiza došli smo do ciljne arhitekture PKI sistema, koji je dao najbolje rezultate u praktičnoj primeni savremenim poslovnim okruženjima. Za razvoj digitalnih sertifikata presudne su informacije, jer pružaju podatke na osnovu kojih korisnici elektronskih servisa,donose efikasnije i efektivnije odluke i samim tim povećavaju stepen zadovoljstva života. Ključne reči: digitalni sertifikat, digitalni potpis, kriptografija, informaciono-komunikacione tehnologije, elektronski dokument, elektronsko poslovanje, statistička kontrola procesa.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.
