Red black cryptography

Cryptography is defined as the practice and study of techniques for secure communication in the presence of third party attackers. It is a good way to protect sensitive information. Over the years, the need to protect information has increased. Confidentiality is of utmost importance. Complete protection of information is not an easy task. In this paper, a method is proposed that consists of three different levels of encryption, accomplished using Red Black Trees and Linear Congruential Generator. Due to the existence of three levels, it becomes extremely difficult for an attacker to hack data.
