Testing and analysis of attacks on the Kerberos cryptoprotocol using the authentication system software stand

Kozlov Alexander Vladimirovich

The article discusses the cryptographic protocol Kerberos, which allows for mutual authentication of the service and the user, while not using the user's encryption key explicitly to access the services. This algorithm is the result of a long evolution of one of the variations of the Needham-Schroeder protocol. The article presents the structure of a test bench for modeling the main attacks on the Kerberos cryptographic protocol and analyzing its vulnerabilities. The article describes the results of modeling the main attacks on the Kerberos cryptographic protocol and analyzes the main vulnerabilities of this protocol. This article is useful for conducting cryptanalysis of the Kerberos protocol and further development of this protocol, for example, for implementing multi-factor authentication in multifunctional information systems.

Keywords:authentication, protocol, Kerberos, kerberization, vulnerabilities.
