A secure framework for file encryption using base64 encoding

Abstract

File security is the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, or destruction of files stored on a database. Nowadays, security has become a very challenging issue, as the number of attacks on cyber security has increased which has affected the confidentiality, authentication, integrity, and availability of files. Here, we are assuring confidentiality and integrity aspects. To cope up with today’s security demands, we propose a secure method to provide security to all types of file formats using AES (Rijndael) and Base64 encoding, which will be later stored on MySQL database server in cloud. After thorough research, we did not find a framework which provides dynamic encryption. The model consists of three layers. First layer performs encoding and encryption. The critical aspect of using Base64 is for encoding binary data into ASCII text which can be encrypted, stored, and transmitted. Hereafter, the encoded data is encrypted by AES (Rijndael) algorithm. Second, the encrypted file is stored into MySQL Server, and finally in third step processing is done through cloud, which protects the critical information from larceny, data leakage, and deletion, thereby providing a total of three security layers.
