“…It gets its name from the fact that its round function uses two different SubCells algorithms. AddRoundKey, Sub-Cells, MixRows, and MixColumns are some of the sub-functions that are available to you when you use the round function [24]. A number of round features, including AddRoundKey, SubCells, MixRows, and MixColumns, are available in Figure 1.…”

Recently low-resource devices such as radio frequency identification (RFID), internet of things (IoT), and wireless sensor networks (WSN) using lightweight cryptography (LWC) to protect devices. Created or design low-resource devices with a lightweight cryptographic technique should take into account important factors such as the battery life and the amount of data to be processed. This paper provides a new hardware designed for Loong lightweight cryptographic algorithm that takes into account the previously described constraints. The new hardware architecture for Loong algorithm with resource sharing to reduce system designed. The proposed approach is implemented using ISE Xilinx V14.7 using Virtex 4 field programmable gate array (FPGA) platform. The synthesis analysis for ISE showed the throughput of 851.264 Mbps with efficiency of 2.282 Mbps/slice, and a power consumption of 0.193 Watt. The implementation designed show the all-algorithms size consists of 373 slices, and the maximum possible operating frequency is 212.816 MHz. To the best of our knowledge, this is the first time that Loong algorithm has been implemented on FPGA using very high-speed integrated circuit hardware description language (VHDL).

“…This method was successfully applied to block cipher based on Feistel network with ARX-like round function: SPECK, TEA, etc. The method described above is more suited to ciphers with a fairly simple round function, which does not assume the division of the input value into words (for example, for most well-known lightweight cryptography algorithms [22][23][24][25][26][27][28][29][30][31][32][33]). This is explained by the fact that when themodulo addition and rotation operations are applied to the whole input value, constructing partial DDT for such a round function is simple enough.…”

This paper presents the results of differential cryptanalysis of the lightweight block cipher Cypress-256. The method for searching multi-round differential characteristic of the block cipher Cypress-256 is proposed. The searching assumes 1) building a big set of one-round differential characteristics and search for possible combinations of one-round characteristics into multi-round ones; 2) extending one-round differential characteristics with the probability up to certain threshold into multi-round characteristics. The following experiments show that the most probable one-round differential characteristics have input differences with 4-6 active bits which are distributed between different words. Besides that, high-probable one-round differential characteristics, which output differences have a small Hamming weight, cannot be extended to build high-probable multi-round differential characteristics. Due to application of the method assuming extension of one-round differential characteristics into multi-round ones, the differential characteristic up to 6 rounds was built, so 10-round block cipher Cypress-256 is resistant to differential cryptanalysis according to the requirements of practical criterion.

“…In recent years, many well-designed lightweight block cipher algorithms have emerged in the field of IoT applications [20][21][22]. Some lightweight block ciphers use the S-box as the nonlinear part, and some block ciphers such as ARX algorithms use the addition operation as the nonlinear part.…”

The lightweight encryption algorithm based on Add-Rotation-XOR (ARX) operation has attracted much attention due to its high software affinity and fast operation speed. However, lacking an effective defense scheme for physical attacks limits the applications of the ARX algorithm. The critical challenge is how to weaken the direct dependence between the physical information and the secret key of the algorithm at a low cost. This study attempts to explore how to improve its physical security in practical application scenarios by analyzing the masking countermeasures of ARX algorithms and the leakage causes. Firstly, we specify a hierarchical security framework by quantitatively evaluating the indicators based on side-channel attacks. Then, optimize the masking algorithm to achieve a trade-off balance by leveraging the software-based local masking strategies and non-full-round masking strategies. Finally, refactor the assembly instruction to improve the leaks by exploring the leakage cause at assembly instruction. To illustrate the feasibility of the proposed scheme, we further conducted a case study by designing a software-based masking method for Chaskey. The experimental results show that the proposed method can effectively weaken the impact of physical attacks.
