Realm 데이터베이스 암·복호화 프로세스 및 기반 애플리케이션 분석

Abstract

Due to the widespread use of mobile devices, smartphone penetration and usage rate continue to increase and there isalso an increasing amount of data that need to be stored and managed in applications. Therefore, recent applications usemobile databases to store and manage user data. Realm database, developed in 2014, is attracting more attention fromdevelopers because of advantages of continuous updating, high speed, low memory usage, simplicity and readability of thecode. It also supports an encryption to provide confidentiality and integrity of personal information stored in the database. However, since the encryption can be used as an anti-forensic technique, it is necessary to analyze the encryption anddecryption processes provided by Realm Database. In this paper, we analyze the structure of Realm Database and itsencryption and decryption process in detail, and analyze an application that supports an encryption to propose the use casesof the Realm Database.
