“…In paper [9], Tigris cipher is designed based on pure algebraic, cryptography basis and secret-key block cipher that is applicable for a limited resource environment and securing fast encryption. Many researchers proposed cryptography systems for increasing the security level and quality of the encrypted data using a fuzzy logic system [10,11,12,13].…”

Nowadays, the security of confidential data is the vital issue in the digital world. Information security becomes even more essential in storing and transmitting data while online. For protecting digital data and achieving security and confidentiality over an insecure internet, the iterative Bat-Genetic Encryption Technique (B-GET) is proposed. The main stages of B-GET are preprocessing, encryption process, bat algorithm steps, and genetic processes. B-GET also comprises an arithmetic and logical operators that increase encryption quality. Empirical results show that the reconstructed data is a copy of the original. It also demonstrates that B-GET technique has a large space key and several defensive stages that resist many attacks and it has strong security based on multiple steps, multiple variables, and the main stages of the B-GET technique. Encrypted data is nearly random and does not contain any indication to secret data.

“…Thus, the design of robust cipher structure has been proposed to deal with modern attacks as well as provide high protection level against malicious attacks. The present algorithm involves a series of developments via long process research has been used by authors for several years, as its design idea as well as the internal structure rely on various block cipher models that have been historically developed and recently published, such as Euphrates cipher, Tigris Cipher and FAROQ cipher designed by (Dawood et al, 2015a;2015b;2015c). These symmetric ciphers have been proposed by the same author and published recently.…”

This paper proposes a new symmetric secret-key cipher for construction of block cipher model. This new approach is considered as a smart step that can be applied to the long process research of modern designing methods used in developing earlier symmetric algorithms. The present cipher can encrypt block lengths of 128-bit by employing Substitution-Permutation Network (SPN) structure. The present cipher uses three options of strong ciphering-key along with variable lengths of 192-bit for 12 rounds, 128-bit for 10 rounds and long ciphering key of 256-bit for 14 rounds similar to standard ciphers. The proposed algorithm has been designed to trust applications that are based on Bitcoin and cryptocurrencies. The current algorithm intended to encrypt addresses of Bitcoin wallet that work quite similar to the e-mail address. The bitcoin wallet includes sensitive information like private secret keys and derived password that are highly confidential. The Advance Encryption Standard (AES) is employed to encrypt most of the bitcoin wallet database. The proposed cipher can act as a good substitute for the standard cipher that allows trusting the Bitcoin wallet database with high security and with a much more complex scheme. The key goal of the submitted algorithm is to build a new enhanced modern cipher with a secure and efficient applicable algorithm that can be used for crypto currencies applications employing a wide trail design strategy.

Abstract-In this paper, we have proposed a new iterated symmetric cipher, which is designed with Substitution and Permutation Network (SPN) structure and depends on strong mathematical built. It uses a compact algorithm for encryption and decryption processes, which consists of four main stages that roughly similar in its work to the Advance Encryption Standard (AES) stages. Starting by the SubByte operation, ReversibleShiftrows operation, ReversibleMixcolumns operation, and Round key addition. The proposed operations in this cipher have implemented in a straightforward manner relatively in both Encryption/Decryption by an elegant way. These four stages designed to reduce the hardware requirements and to produces high efficiency, which keeps the encryption and decryption process at the same speed in the hardware devices and eliminates the difference of execution times as well as creates a balance in forward and backward operations. The proposed cipher interested with modern design by adopted new algebraic operations and clear mathematical notations to ensure a high level of security. The proposed cipher did not build suddenly or arbitrarily but it acts as a sequence of developments and represents as a long process of design for long time, since several proposed ciphers have been published recently by us that paved the way to its new design, so the designed cipher inherited a good properties from a proven famous algorithms' features to produce high resistance against all known attacks and to submit a high performance on many platforms and in a wide range of hardware and software applications.
