“…The proposed cipher is a result of the long development process for some published algorithms that opened the door in front of the design idea. These algorithms inspirited the proposed cipher many good features and the attractive internal structure as explained in [31][32][33] as a previous works. There are several effective criteria and important conditions that must be satisfied through the design process which can be summarized as follows:…”

<p>In the present paper, a new cryptographic lightweight algorithm has been developed for the Internet of Things (IoT) applications. The submitted cipher designed with the involution Substitution Permutation Network SPN structure. The involution structure means that the same encryption algorithm is used in the decryption process except the ciphering key algorithm is applied in reverse order. The introduced algorithm encrypts the data with a block size of 128-bit 192-bit or 256-bit, which iterative with 10, 12 and 14-rounds respectively similar to the AES cipher. The design aspect supports an elegant structure with a secure involution round transformation. The main round is built without S-Box stage instead that it uses the on-fly immediate computing stage and the involution of mathematical invertible affine equations. The proposed cipher is adopted to work in a restricted environment and with limited resources pertaining to embedded devices. The proposed cipher introduces an accepted security level and reasonable Gate Equivalent (GE) estimation with fast implementation.</p>

“…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.

“…Dawood [21] suggested a new iterated symmetric cipher, which is designed with Substitution and Permutation Network (SPN) structure and depends on strong mathematical built. It uses a algorithm for encryption /decryption processes, which consists of four main stages that roughly similar in its work to the Advance Encryption Standard (AES) stages.…”

Abstract-With the increase in use of digital technology, use of data items in the format of text, image and videos are also increases. To securely send this data, many users and smart applications have adapted the image encryption approach. But the existing concepts are based on general AES approach. There is need to securely send the data with the addition of some expert image encryption and key generation approach. In this paper, we are using Matrix Array Symmetric Key (MASK) for the key generation and Chaos based approach for the image encryption. The main function of MASK is to generate the key for the encryption and decryption. The encryption process involves the generation of key. We have considered the key of MASK-256 for the encryption having 16 rounds. Chaos based concept has been considered for the encryption of image. Here, permutation-substitution based chaos based approach has been adopted for the image encryption. Moreover, in this approach, we have adapted the concept of partial encryption of image pixels instead of complete encryption so that in case of arrack, intruder can be confused with the partial encrypted image. In this approach, different image samples having different sizes have been considered. Further, concept is evaluated based on the parameters of Information Entropy, Elapsed Time, Precision, Recall and F-Measure.
