Abstract [eng] There is a lot of internet shopping done nowadays. People are buying goods from electronic shops and paying for them in online payment systems. These systems need to provide secure user authentication method for user to log in and to pay for the goods. The main purpose of this work is to create and investigate new online payment system with better user authentication method. This method is based on user’s electronic signature. In this work there were investigated the most popular online payment systems to find out which authentication method they are using to authenticate user. All of those systems provide password based user authentication which we found to be not secure enough because there are some ways for third party to find out users passwords. There were also investigated most popular user authentication methods to find out their advantages and disadvantages. After implementation of new online payment system’s user authentication method there was done investigation of this method. There were done some researches to find out this authentication method advantages and disadvantages. It was found that this method is more secure because it uses PKI (Public Key Infrastructure) which ensures integrity and authenticity. New authentication method was compared with existing authentication method used in real online payment systems and found that it takes twice longer time for user to be authenticated than it is done in existing online payment systems. But it takes only about 100 ms to be authenticated which user won’t feel. Also new authentication method may be difficult for user to use so before using it in real life he needs to be trained. There were also investigated possible solutions of using different types of order file formats and electronic signature methods.
