摘要:One implementation of the use of Information and Communication Technology (ICT) via the internet is sending text messages via email, social media, or other means of communication. Nearly all messages sent privately over a private network are secret messages that you don't want to share with other people, be they text messages, voice messages, picture messages, and video messages. But in reality, confidential information is often leaked so that confidential information can be spread to various irresponsible parties. The efforts made by these parties are aimed at misusing the data sent by destroying, intercepting, changing the original message according to the wishes of other parties for their own interests. This action can make confidential information or messages visible to people who are not responsible. In overcoming this data security issue, steps are needed to improve data security. One technique that can be used to secure data is to use the Modular Multiplication based Block Chipper (MMB) algorithm, which is a simple method that is not too complicated but is hidden so that the message to be sent is safe. In this research, we propose an algorithm that simplifies the use of MMB by directly multiplying each plaintext to the key, and changing the constant C using RoL so that the binary in constant C is doubled. The results of the implementation of this study concluded that the encryption of the original message would be longer, and it would be more difficult for other parties to crack.
