“…This encoding table is a 24 * 4 matrix of 96 American Standard Code for Information Interchange (ASCII) characters consisting of alphabets, numbers, and special characters. Later this table was used and extended by other researchers [11]- [13]. It is evident that the utilization of this table in an algorithm has improved the randomness of ciphertext and consequently enhanced the system security.…”

“…An extended version of the ASCII table was introduced with 256 ASCII character encoding [11]. For a dynamic sequence, table creation, all characters are initially allocated randomly to DNA base sequences followed by an iterative rearrangement using a mathematical pattern, whereas in the encryption process, the plaintext is first converted into DNA bases using the sequence table, followed by the creation of data chunks to encrypt them using an asymmetric cryptosystem and finally to merge the chunks as the ciphertext.…”

The study of encryption/decryption of information is known as cryptography. The need of protecting information from old years until now is the reason of appearing the process of hiding information from unauthorized people to access it. In this research paper, a cryptographic system is designed by using the DNA computing concepts and random permutation. The proposed system is a block symmetric cipher that uses one initial key in which will be used to generate permutations as many as needed, convert the initial key to DNA key, convert plaintext block to DNA bases. The remaining needed DNA keys are produced through the cipher/deciphering processing. Different operations applied: permute using permutation, modulo and XOR operations to perform the encryption/decryption process. Using the DNA based cryptography enhance the information security and produce highly efficient cipher systems.

The main purpose of the data encryption process is the difficulty of understanding the content of the message with the difficulty of detecting the encryption mechanism. Therefore, in this paper, we proposed a new model of encryption based on the idea of encrypting text messages and gray images using amino acid chains. Amino acids are distinguished by being a series of alphabets represented by 20 characters and do not have a specific length. The main idea of this paper is to get an amino acid chain that contained encrypted message. To develop this model, we construct an artificial lookup table to encrypt any character of message to the amino acid chain, after that applying encryption process. The proposed model was applied on different kinds and sizes of messages, which proved the success of the main idea of the research, which is obtained amino acid chains with encrypted messages. The proposed model appears efficient in real time of encryption and extraction process compared with known methods. In the end, we compared the amino acids that we extract on the process of encrypting with internationally known amino acids and we found a similar ratio, which proves that the proposed model is effective in terms of increasing ambiguity of the encrypted message.
