Web application for secure instant messaging

V magistrski nalogi so predstavljene tehnologije, ki nam omogočajo varno sporočanje z uporabo spletnih tehnologij. Predstavili smo tudi mehanizme varovanja in šifriranja podatkov na spletnih kanalih ter vrste trenutno znanih napadov na podatke izmenjane preko protokola HTTP. Na podlagi raziskave trenutno obstoječih rešitev za varno sporočanje smo ugotovili, da rešitve že obstajajo, vendar so plačljive, ali pa ne zagotavljajo dovolj visoke stopnje varnosti. Razvili smo lastno rešitev, ki upošteva načela varne komunkacija in vključuje tehnologije, ki omogočajo varno, predvsem pa zasebno komunikacijo.In the master\u27s thesis there are presented technologies which enable secure instant messaging with the use of web technology. There were also introduced mechanisms of security and encrypting data on web channels and the kinds of actually known attacks to data exchanged over the protocol HTTP. According to research of the actually existing solutions for secure instant messaging it was found out that solutions already exist but they are payable or do not guarantee an adequate high level of security. An own solution was developed which considers the principles of secure instant messaging and includes technology which enables secure but most of all private communication
