Data security is a matter of maintaining the confidentiality of information, especially those containing sensitive information that only authorized parties may know, especially if the transmission is done via a public network, what if the data is not secured first, it will be very easy to be tapped and retrieved. know the contents of the information by parties who do not have the authority. One way to secure it is to use cryptographic techniques, namely by using the Lucifer algorithm technique and then randomizing the keys based on the Naïve Shuffle, this is done so that the keys in the data are much more random and not easy to find out the contents. This technique can minimize the occurrence of a leak of confidential messages, and the sender does not have to worry about the message. This research is expected to produce and show results in securing messages and to make it easier for the community to secure secret messages.
