Statistics model of automated management of digital certificates

In this dissertation, the development of digital certification involves the introduction of the concept of PKI (Public Key Infrastructure) system, which incorporates many elements and phenomena in the field of computational statistics, information - communication technologies and electronic commerce. 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.
