摘要：Now a day computer networks are growing day by day. With this growth these networks are required tobe inter connected with each other which leads to the major usage of internet. Although internet makes accessibilityeasier for these networks but it decrease data security i.e not acceptable by any user. Hence to increase data security werequired strong cryptography in authentication protocol .Kerberos is one of the best window authentication protocolsbut one of the major drawback of Kerberos is Replay attack. In this attack the intruder replays the same ticket to theapplication server to use services again and again. Hence we are trying to increase security notations in Kerberos inorder to minimize replay attacks. We using a random number generated by TGS. This random number is being used byTGS in a key which is required to encrypt ticket by TGS.
