E. parašo taikymas autentifikavimui ir šifravimui video paskaitų sistemoje / Authentication and encryption using digital signature in video lecture system

Lenza, Mantas 25 August 2010 (has links)
Šiuolaikinės informacijos perdavimo technologijos leidžia organizuoti video paskaitas ir tam yra kuriamos video paskaitų sistemos. Išanalizavus egzistuojančias video paskaitų sistemas buvo iškeltos kelios problemos: • nepakankamas pateikiamos informacijos saugumo lygis; • nesuteikiama galimybė dėstytojams realiu laiku modifikuoti mokomosios medžiagos turinį. Pateiktų problemų sprendimui pasiūlytas sistemos modelis, kuriame akcentuojamas vartotoju autentifikavimas e. parašu ir pateikiamos informacijos šifravimas. Šias problemas pavyko sėkmingai išspręsti panaudojant populiarius ir kriptografiškai saugius algoritmus. Suprojektuota sistema sėkmingai išbandyta, o atlikus eksperimentini tyrimą nustatyta, jog sistemos funkcionalumas niekuo nenusileidžia standartinėms paskaitoms. / Modern communication technology allows you to organize video lectures and that’s why the systems of video lectures are created. . After the analysis of existing video lectures systems, several issues have been raised: • low security level of the proposed information; • not given access to the teachers to modify the content of teaching materials in real time. For the solution of the problems the model of the system is suggested which focuses on the authentication of the user by the e. signature and the encryption of the given information. These problems have been successfully solved by using popular and secure cryptographic algorithms. Designed system is successfully tested, and, after a pilot study was found that the functionality of the system is as good as the standard lectures.
