Improved Kerberos protocol based on public key encryption algorithm of braid groups

To improve the security of Kerberosprotocol, the hard problem is adopted which is constructed by combining the non-conjugate transformation and multi-variable equations based on braid groups, the public key encryption algorithm Kerberos protocol and the KBGS (Kerberos on braid groups system) based on this protocol is proposed, the system strengthens the communication safety intensitybetween the client and the certification center. The results show that the improved Kerberos protocol can resist high-intensity clear text attacks, and it can be well applied to PKI platform of the quantum computer, therefore, it has more security and practicality.
