Android Security: Security using Encryption (AES)

Abstract

Security is an essential aspect of the software we develop. Data with which we deal is sometimes important and should be made secure. In case of android the database that we use is SQLite which is a very light database, which is very less secure, it has no type encryption or decryption available. Data stored in SQLite can be easily retrieved if our android device gets into wrong hands. Various tools are also available online which help in extracting data from SQLite database. My project is related to security of data provided using encryption. The encryption method I am going to use is Advanced Encryption Standard (AES) which is the best known symmetrical encryption available. In the project AES is implemented in java and is used to secure our data in database. Application vendors like facebook, twitter, etc. which are big companies have their own security and use servers to store and retrieve data, because the security provided by android is not enough. The code of AES implemented in the project can be used in any application as an API to provide security to the data being stored. So the project mainly focuses on the implementation of AES and demonstrating its usage in android database SQLite. The idea of the project came from AOSP (Android Open Source Project) where this problem has been mentioned.
