  Abstract

Most of popular mobile messengers nowadays are based on centralized servers. The contents of the message transmitted through the server are stored in the server for a certain period of time. Therefore, if the server that holds the data is hacked, the security of the stored data is not guaranteed. In existing mobile messengers, when data stored in the server is leaked by an attacker or by an insider, there is a problem of data forgery and privacy infringement. In addition, problems due to server overload that occurs when service volume increases are frequently occurring. In this paper, we propose a new mobile messenger that solves the problems. The proposed mobile messenger uses Ethereum"s Whisper to transmit data without using a server, and also supports management and transmission of mobile coupons. All transmitted data is encrypted and transmitted to ensure the confidentiality of the data and to ensure integrity and authentication of the message through digital signatures.
