The security of Internet of Things (IoT) is a challenging task for researchers due to plethora of IoT networks. Side Channel Attacks (SCA) are one of the major concerns. The prime objective of SCA is to acquire the information by observing the power consumption, electromagnetic (EM) field, timing analysis, and acoustics of the device. Later, the attackers perform statistical functions to recover the key. Advanced Encryption Standard (AES) algorithm has proved to be a good security solution for constrained IoT devices. This paper implements a simulation model which is used to modify the AES algorithm using logical masking properties. This invariant of the AES algorithm hides the array of bits during substitution byte transformation of AES. This model is used against SCA and particularly Power Analysis Attacks (PAAs). Simulation model is designed on MATLAB simulator. Results will give better solution by hiding power profiles of the IoT devices against PAAs. In future, the lightweight AES algorithm with false key mechanisms and power reduction techniques such as wave dynamic differential logic (WDDL) will be used to safeguard IoT devices against side channel attacks by using Arduino and field programmable gate array (FPGA).

The proposed algorithm called Image encryption based on chaos, elliptic curve, dynamic S-boxes and variable permutations (IECC) is a symmetric cryptosystem for encrypting bmp images, in this case 512 × 512 pixel figures are used for testing. This algorithm consists of 15 rounds with a different S-box for each round and each set of S-boxes is different for each image encryption. Based on the above, a permutation is applied before the first round, additionally, in round 15 the inverse permutation of the first round intervenes. Both the S-boxes and the permutations are built using the E. Lorenz equations, which obtain solutions with two different points of the elliptic curve chosen randomly in each process. To measure the resistance to differential attack of the proposed cryptosystem, the following measurements are carried out: Number of Pixels Change Rate - NPCR, Unified Average Changing Intensity - UACI. Also, taking into account that the generation of the boxes is dynamic, the algebraic attack is avoided; furthermore, with this symmetric cryptosystem it is possible to distribute keys and sign, since an asymmetric system is used in its construction. On the other hand, four types of noise are applied to the encrypted images to evaluate the resistance of the encryption algorithm to this type of attack. Ten instruments are used to measure the quality of encryption; namely: entropy, correlation, discrete Fourier transform, NPCR, UACI, Avalanche Criteria - AC, contrast, energy, homogeneity and a goodness of fit test is proposed using the χ2 distribution.

“…Further results proved that their scheme was consistent and suitable for protected communication. Altigani et al [12] implemented cryptanalysis for an image encryption procedure by creating an S-box based on the chaos principle. Their system offered the benefits of simple organization, good encryption performance and high encryption effectiveness.…”

“…The first sub-diffusion layer called the shift row uses the technique of shifting the rows of the overhead layer output. The second sub-diffusion layer called the mixed column is a matrix with continuous entries, each with a 4-byte column represented as a vector, which is then multiplied in a fixed 4×4 matrix [12].…”

<span lang="EN-US">Substitution boxes are essential nonlinear modules that are popular in block ‎cipher algorithms. They ‎also play a significant role in the security area because of ‎their robustness to different linear ‎cryptanalysis. Each element of the state in a S-‎box is nonlinearly replaced using a lookup table. This ‎research presents the S-‎box, one of the fundamental parts of the advanced encryption standard ‎‎(AES) ‎algorithm. The S-box represents the confusion part in the AES. However, when ‎information ‎is shared between different devices in an authorized manner, the ‎algorithm should be able to ‎combine a sufficient number of confusion layers to ‎guarantee the avalanche effect (AE). ‎Subsequently, this research selects the best ‎S-box by comparing different sizes (4×4, 8×8, and ‎‎16×16) and measuring them ‎on the basis of the million-bit encryption. The AE is the main criterion ‎used in ‎choosing the best S-box. A robust and strong cryptography algorithm should be ‎able to ‎confirm the AEs. Results indicate that the 16×16 S-box with a 52% AE ‎ratio is the superior S-box</span>
