“…This design of dynamic S-Box achieves the non-linear confusion and hence the cryptanalysis of the ciphertext becomes very difficult. Similarly, LiCi is a lightweight block cipher that uses the Feistel structure and active S-Boxes and is suitable for both software and hardware platforms, especially when energy is the main constraint [ 20 ]. It shows good resistance against many cryptanalytic attacks.…”

A symmetric block cipher employing a substitution–permutation duo is an effective technique for the provision of information security. For substitution, modern block ciphers use one or more substitution boxes (S-Boxes). Certain criteria and design principles are fulfilled and followed for the construction of a good S-Box. In this paper, an innovative technique to construct substitution-boxes using our cubic fractional transformation (CFT) is presented. The cryptographic strength of the proposed S-box is critically evaluated against the state of the art performance criteria of strong S-boxes, including bijection, nonlinearity, bit independence criterion, strict avalanche effect, and linear and differential approximation probabilities. The performance results of the proposed S-Box are compared with recently investigated S-Boxes to prove its cryptographic strength. The simulation and comparison analyses validate that the proposed S-Box construction method has adequate efficacy to generate efficient candidate S-Boxes for usage in block ciphers.

In wireless sensor networks, the sensors transfer data through radio signals to a remote base station. Sensor nodes are used to sense environmental conditions such as temperature, strain, humidity, sound, vibration, and position. Data security is a major issue in wireless sensor networks since data travel over the naturally exposed wireless channel where malicious attackers may get access to critical information. The sensors in wireless sensor networks are resource-constrained devices whereas the existing data security approaches have complex security mechanisms with high computational and response times affecting the network lifetime. Furthermore, existing systems, such as secure efficient encryption algorithm, use the Diffie–Hellman approach for key generation and exchange; however, Diffie–Hellman is highly vulnerable to the man-in-the-middle attack. This article introduces a data security approach with less computational and response times based on a modified version of Diffie–Hellman. The Diffie–Hellman has been modified to secure it against attacks by generating a hash of each value that is transmitted over the network. The proposed approach has been analyzed for security against various attacks. Furthermore, it has also been analyzed in terms of encryption/decryption time, computation time, and key generation time for different sizes of data. The comparative analysis with the existing approaches shows that the proposed approach performs better in most of the cases.

“…As we can see in architecture divided into two sections first one is key scheduling process and second one is round function, for the connection of the two parts of architecture we gave interconnect node which names are s1, s2, s3, s4, s5, s6. In key scheduling process Y*[0] to Y* [7] is rotated constant key and K0 to K5 are constant key are adding with 32-bit module operation. RR1 to RR6 are rotated register 1 to 17 bit left rotation operation are perform in this registers.…”

High-throughput lightweight cryptography calculation is the need of the present world to convey between two asset obliged devices Pipelining is the technique have been used to achieve high throughput. In this paper we have target to lightweight block cipher LEA. Block size of LEA is 128 and key size 128, 192, and 256 bit. In this paper we have focus on LEA architecture for 192- bit key size and achieve very good throughput. This method has a higher capability of throughput as compared to previous LEA ciphers. Proposed work is 56% improved version of compared paper for respective Speed and area also less than previous architecture. Graph representation have been shown of different matrices and comparison.
