Introduction

In today's digital age, securing voice messages has become a crucial aspect of communication. With the increasing use of mobile devices and digital platforms, the need for secure and efficient voice message transmission has never been more pressing. One technique that promises high security is the three-pass protocol, which allows the sender and recipient to communicate without the need to exchange keys. In this article, we will explore the application of three-pass protocol using Massey-Omura Cryptosystem and Leventein Code on Android devices.

Understanding Three-Pass Protocol

The three-pass protocol is a cryptographic technique that enables secure communication between two parties without the need for key exchange. This protocol involves three steps:

Key Generation: The sender and recipient generate a shared secret key using a public key encryption algorithm.
Encryption: The sender encrypts the message using the shared secret key.
Decryption: The recipient decrypts the message using the shared secret key.

Massey-Omura Cryptosystem

The Massey-Omura Cryptosystem is a public key encryption algorithm that operates based on the three-pass protocol. This algorithm is known for its efficiency in securing messages, as the private key is obtained through a very large number of factors, which is only known by the sender and receiver. However, the disadvantage of Massey-Omura is the size of a large encryption product, which can hamper the process of sending messages. Therefore, compression techniques are needed to reduce encrypted messages.

Leventein Code

In this context, Leventein Code appears as a lossless compression solution that can be applied to voice messages. Leventein Code allows voice messages to be compressed without losing information, which is very important in the context of audio communication. This code is based on the concept of Huffman coding, which assigns shorter codes to more frequently occurring symbols in the message.

Implementation on Android

In this study, the voice message was first encrypted using Massey-Omura Cryptosystem and then compressed using Leventein Code. The implementation was done on Android devices using the Java programming language. The results showed that the combination of Massey-Omura Cryptosystem and Leventein Code in three-pass protocol can restore messages to its original form after the encryption and compression process.

Results

The results of this study include:

Compression Ratio: 30.503%
Ratio of Compression: 3,392
Space Savings: 69,497%
Bitrate: 1,854,413

These values indicate the effectiveness of the method used, where the high level of compression is balanced with the ability to maintain the quality of the message.

Conclusion

The application of three-pass protocol using Massey-Omura Cryptosystem and Leventein Code on Android devices shows that cryptographic and compression technology can be integrated into mobile applications, making it relevant and useful in the context of daily communication. In the future, further development of this technique can have a positive impact in improving the safety and efficiency of sending voice messages on various digital platforms.

Future Work

Further research can be done to improve the efficiency of the Massey-Omura Cryptosystem and Leventein Code. Additionally, the implementation of this technique on other digital platforms, such as iOS and web applications, can be explored.
