In this time of technological advancement everything is online and so is the voting. The online voting is time saving, efficient, reliable and fast. The online voting requires safety for the communication setup between client and server so for that purpose Kerberos protocol is used in the voting process for the authentication purpose which uses DES cryptography but DES is not secure enough to handle highly valuable data used in voting so in order to make it more secure we need to replace DES with some other cryptography technique. Kerberos uses DES by default, but it easy to decrypt so to enhance its security we need to replace it with AES cryptography. So here in this paper, we will discuss AES cryptography as the replacement of DES and its implementation with Kerberos. As AES is mathematically more efficient than DES other than that it allows choosing a 128-bit, 192-bit or 256-bit key as compared to the 56-bit key of DES thus making it exponentially stronger.
