Abstract

Recent news broke out that an attacker broke data privacy by obtaining encryption keys with the help of backdoors or a brute-force attack. Once the key has been exposed, the only way of preventing the file excess is to limit the permission of the attackers. This can be performed, for example, by distributing a block of ciphertext across networks, if the enemy cannot compromise all. However, if the files are encrypted with an existing algorithm, they can easily break them. In this research, we will research data privacy against an attacker who knows about the encryption key. To conclude this research, we propose a novel algorithm that can protect the data if the attacker already knows about the keys. We explore the bastons security and evaluate its implementation.
