“…Multi-level Data Encryption describes the improvement of data encryption complexity due to multiple operations of single-phase encryption techniques in cryptography. Better security can be achieved by multiple encryptions because even if some component ciphers are exposed or some of the secret keys are detected, the confidentiality of the original data can still be maintained by the multiple encryptions 11 .…”

The technological development in the field of information and communication has been accompanied by the emergence of security challenges related to the transmission of information. Encryption is a good solution. An encryption process is one of the traditional methods to protect the plain text, by converting it into inarticulate form. Encryption implemented can be occurred by using some substitute techniques, shifting techniques, or mathematical operations. This paper proposed a method with two branches to encrypt text. The first branch is a new mathematical model to create and exchange keys, the proposed key exchange method is the development of Diffie-Hellman. It is a new mathematical operations model to exchange keys based on prime numbers and the possibility of using integer numbers. While the second branch of the proposal is the multi-key encryption algorithm. The current algorithm provides the ability to use more than two keys. Keys can be any kind of integer number (at least the last key is a prime number), not necessarily to be of the same length. The Encryption process is based on converting the text characters to suggested integer numbers, and these numbers are converted to other numbers by using a multilevel mathematical model many times (a multilevel process depending on the number of keys used), while the decryption process is a one-level process using just one key as the main key, while the other keys used as secondary keys. The messages are encoded before encryption (coded by ASCII or any suggested system). The algorithm can use an unlimited number of keys with a very large size (more than 7500 bytes), at least one of them a prime number. Exponentiation is also used for keys to increase complexity. The experiments proved the robustness of the key exchange protocol and the encryption algorithm in addition to the security. Comparing the suggested method with other methods ensures that the suggested method is more secure and flexible and easy to implement.

“…The rapid devolvement of internet and secure transmission of personalized and secure transmission of data may lead the attention in this area. Data security issue of electronic data communication incorporates the different area including secure medium for communication, effective encryption techniques and trust based third party for maintaining the database [1] rapid use of hand-handled device like smart mobile phones, (PDA) personal digital assistance as well as application such as a e-payment, secure messaging etc need more security than conventional security [2]. Since there are various use of digital devices and advance applications which involve in financial transaction and transfer the secure data through electronic communication.…”

In the data communication, the intriguing issue to provide data security and these led to comprise the many areas including the impregnable medium and trusted third party to maintain a database and various types of encryption techniques. These are main inducement of researchers in this area to protect the data from unauthorized users for malicious purpose. Therefore there are requires the different types of encryption and decryption techniques to secure the data. In the proposed paper, there are used the Tangent and Cotangent rules to generate the cipher and decipher at sending and receiving ends respectively. At the sending side, take the message alphabets which message want to communicate through electronic communication and find the corresponding values of alphabets from standard alphabetical table and apply the rules of Tangent. Find the corresponding values of Tangent of a particular alphabet and use this value as cipher at sending end. At the receiving end, there are taking the value of Cotangent of those particular receiving alphabets. Finally, get the value of same alphabets. This paper provides an algorithm as well as validates the proposed mechanism through UML Diagram.
