Abstract

Telephony over IP (ToIP) is a cost-saving communication technology based on voice over IP (VoIP) that enables enterprises to reduce communication fees. However, ToIP faces many security threats due to its IP-based nature. This work aims to improve ToIP security using cryptography and blockchain technology. The authors propose a secure approach to user registration, authentication, communication session establishment, and communication data storage. The proposed solution leverages blockchain technology to ensure the integrity, confidentiality, and availability of communication data. By implementing this solution, the researchers aim to enhance the security of ToIP networks and protect them from cyber threats. This approach provides a secure and reliable way to support ToIP services while preserving confidentiality and privacy.

Introduction

Telephones are an important tool in the business world. It’s the principal source of contact between enterprises and customers. Since its creation in 1876 by Alexander Graham Bell (https://www.history.com/this-day-in-history/alexander-graham-bell-patents-the-telephone, 2022), telephone use hasn't ceased to increase. So telephonic communication takes a great place in enterprise development, and then, country development. The report is that, with traditional telephony, we spend more and more on our telephonic communications. The table below, published in November 2021 in the annual activities report of RAECP (Regulatory Authority for Electronic Communications, posts and Press distribution) in Benin, presents mobile telephonic traffic evolution from 2019 to 2020 in Benin Republic.

In 2020 in Benin Republic, the intra network traffic was 3 913 566 886 minutes (or 234 814 013 160 FCFA for 1 franc/s); in other words, intra network voice traffic and national outcoming voice traffic have known respectively increasing of 3.1% and 1.6% of volume comparatively to 2019. Although considerable efforts are done in order to improve telephonic communication fees, the question remains: How can we reduce telephonic communication fees ?
