The Improved Public Key Encryption Algorithm of Kerberos Protocol Based on Braid Groups

Since the limitations of Kerberos authentication protocol for symmetric algorithm, there are many improved Kerberos protocol of RSA public key encryptions. However, the existing public key encryption system resistance in the analysis of quantum encryption has brought tremendous challenges. Braid group is a new considerable public key cryptography platform for the quantum computer ages. The new intractable problem is proposed by combing the non-conjugate transformation and multi-variable equations on braid groups, whose intensity is strengthened by increasing the number of variables. The public key encryption algorithm based on braid groups is proposed. The novel algorithm is used to improve Kerberos protocol, which can be very good resistance to various attacks. Therefore, it has more security and practicality.
