Abstract

The trend of financial transactions by using a mobile phone or mobile payment increases. By using the mobile payment service, users can save money on mobile phone (handset) and separate from the pulse. For protecting users, mobile payment service providers must complete the mobile payment service with the transaction security. One way to provide transaction security is to utilize a secure mobile payment application. This research provides a safety feature used for an Android-based mobile payment application. This security feature is making encryption rules dynamically named Dynamic Rule Encryption (DRE). DRE has the ability to protect data by means of encrypting data with dynamic rules, and DRE also has a token function for an authentication. DRE token raised with dynamic time-based rules. Here, the time is used as a reference with the order of the day in the year (day of the year). The processes of the DRE’s encryption, decryption, and the DRE’s functionality as the token are discussed in this paper. Here, the Hamming distance metric is employed for having maximum differences between plaintext and ciphertext.

Highlights

The current trend is numbers of mobile phones decreased slowly while smartphones are growing rapidly
A sort of smartphone apps has been made by the developers in Indonesia, for example: GO-JEK has successfully run using smartphone [1], mobile-based academic information system [2], shopping using smartphone [3], mobile payment [4, 5], and mobile service commerce [6]
The rule selection with and without random function will result in differences in distance between the input and output; the way this election may affect the performance of the Dynamic Rule Encryption (DRE)

Summary

Introduction

The current trend is numbers of mobile phones decreased slowly while smartphones are growing rapidly. Trends in financial transactions using a mobile phone or mobile payment increase. One path to provide transaction security is to utilize secure mobile payment applications. This research offers a security feature used for mobile payment applications on the Android operating system. This security feature is a dynamic encryption rule named Dynamic Rule Encryption (DRE). Many existing rules on DRE are limited to certain time. This causes the device to be connected to the server to update the rules DRE. The DRE token contains information about the device, time, mobile payment user’s account, and other information used for authentication
