USING BPMN NOTATION FOR MODELING THE PROCESS OF ISSUING DIGITAL CERTIFICATES

V diplomskem delu predstavljamo poslovne procese, ki vključujejo izdajo digitalnih potrdil. Za modeliranje samih procesov je uporabljena notacija BPMN. Gre za notacijo, s katero lahko na grafičen način predstavimo poslovne procese nekega podjetja. V mnogih podjetjih imajo poslovne procese opisane na listih papirja, to pa seveda otežuje samo razumevanje. V svetu se vedno bolj uveljavljajo t. i. elektronske storitve — storitve, ki jih je mogoče opravljati prek interneta in drugih elektronskih medijev. Uporabniki pri vseh storitvah zahtevamo ustrezno raven varnosti. Glede na izkušnje in težave, ki so se v preteklosti pojavile pri opravljanju elektronskih storitev, se je kot edini zares varen in zanesljiv sistem zagotavljanja varnosti v elektronskem okolju uveljavil sistem digitalnih certifikatov oziroma potrdil. Digitalno potrdilo je po svojih varnostnih zasnovah enakovredno lastnoročnemu podpisu in zagotavlja ustrezno stopnjo varnosti pri vseh elektronskih storitvah, ki jih opravljamo z njegovo pomočjo. Diplomska naloga obravnava osnovne koncepte modeliranja poslovnih procesov in digitalna potrdila. Praktični del diplomske naloge podaja rešitev v obliki procesa, ki je modeliran s pomočjo programskega orodja ARIS Business Architect.In the diploma paper this researcher presents business processes which comprise issue of digital confirmations. For the modeling of processes we used notation of BPMN (“Business Process Modeling Notation”). It is the notation, which can be helpful, when we describe business processes of certain company in graphic manner. Many companies have business processes described on a peace of paper which enables the understanding. There are more and more electronic services asserted throughout the World. These services can be carried out with help of the internet and other electronic media. The user of internet service demands the appropriate level of security. With help of all the experiences and problems, which have developed in the past, the researchers came to conclusion that the only safe and trustworthy system which ensures security in internet environment is the system of digital certificate and confirmations. Digital confirmation has been developed out on equally important hand written signature which meets security standards in all internet services. The diploma paper presents the basic concepts of modeling business processes and digital confirmations. The practical part of the diploma paper gives the solution in the form of process which is modeled through help of the program tool ARIS Business Architect
