Modern methods for user authentication

The main focus of Master’s thesis is modern methods for user authentication. In the first part are briefly described currently used protocols and pointed out thein advantages and disadvantages. The theoretical introduction analyzes the principles of zero-knowledge authentication, password-based protocols and describes the concept of a new generation hash function. The practical part describes the specific implementation of authentication protocols - Ohta-Okamoto protocol as a representative of the zero knowledge protocols and SRP (Secure Remote Password), which represents password-based protocols. In both cases, the installation procedure is described following the analysis of their implementation (at the source code level) and then compared with the transmitted data captured by Wireshark. The SRP protocol is verified by AVISPA tool. There is summary of both protocols security analysis in the conclusion
