Introduction

In today's digital era, data transactions and communication can be done by anyone, anywhere, and anytime. With the ability of computing and processing on Android-based devices, data processing becomes easier and more practical. However, it is essential for us to ensure that the data is safe from manipulation by irresponsible parties. This is where cryptography plays a vital role, namely the art and science of converting messages into forms that are unknown. One of the cryptographic methods that attract attention is the Massey-Omura algorithm, which uses a public key cryptographic system with discrete logarithmic calculations to improve security.

Background of the Massey-Omura Algorithm

The Massey-Omura algorithm is a modern algorithm designed to increase the level of data security. One of the advantages is the use of a minimum of four digits of prime numbers, whose acceptance is examined using the Agrawal-Biswas algorithm. The use of prime numbers aims to increase complexity in the encoding process, so it is difficult for those who are not authorized to decrypt the message that has been encouraged. This algorithm is based on the concept of public key cryptography, which uses a pair of keys, one for encryption and the other for decryption.

The Three-Pass Protocol Scheme

The Three-Pass Protocol scheme is a method of sending data that allows delivery of information without key exchange between the sender and receiver. This makes this scheme very relevant to be used in data communication, especially on the Android platform that has a connection that is not always safe. The scheme involves three passes: the first pass is used for key exchange, the second pass is used for encryption, and the third pass is used for decryption.

Safety and Efficiency Test

In this study, testing was carried out by securing each byte from the file to be protected, so that the system can function for various file extensions. The results showed the Mean Squared Error (MSE) value of 0 and the value of the Peak Signal to Noise Ratio (PSNR) was infinite. This shows that the method used is able to maintain file integrity effectively, which is one of the main objectives of cryptography. The MSE value of 0 indicates that there is no error in the encryption and decryption process, while the infinite PSNR value indicates that the signal-to-noise ratio is perfect.

Complexity Analysis

In terms of complexity, the Massey-Omura algorithm has a complexity θ(n), which means that processing time will increase with the increase in data size. This is also proven in a graph that shows the relationship between file size and process time, where the graph is linear. On the other hand, the graph that shows the relationship between the type of file extension and the processing time shows stability, which shows that the type of file extension does not significantly affect the process time.

Implementation on Android Platform

The Massey-Omura algorithm was implemented on the Android platform using the Java programming language. The implementation involved the use of the Android SDK and the Java Cryptography Architecture (JCA) to provide a secure and efficient way of encrypting and decrypting data. The implementation was tested on various file extensions, including text files, image files, and video files.

Conclusion

From the analysis conducted, it can be concluded that the Massey-Omura algorithm applied in the Three-Pass Protocol scheme on the Android platform runs well. This implementation shows a great potential as an alternative to securing data, especially in the midst of the need for a strong security system in the increasingly complex digital world. With the ability to secure various file extensions and maintain data integrity, this algorithm can be an effective solution to overcome the challenges of data security in the modern era.

Future Work

Future work can involve the implementation of the Massey-Omura algorithm on other platforms, such as iOS and Windows. Additionally, the algorithm can be modified to improve its performance and efficiency. The algorithm can also be used in other applications, such as secure communication and data storage.
