“…Image encryption has been implementing for fractional-order of dimension three in 2020, where the proposed algorithm was effective according to the security analysis [23]. Finally, elliptic curves were a tool to construct an asymmetric image encryption scheme in 2021 in two different works [24], [25], they were fast and secure in term of generating points on an elliptic curve. In the same year (2021), an approach of image encryption based the time delay of chaotic system has been proposed [26], where they proposed a type of time delay chaotic system to achieve the purpose of the image encryption.…”

Asymmetric image encryption schemes have shown high resistance against modern cryptanalysis. Massey Omura scheme is one of the popular asymmetric key cryptosystems based on the hard mathematical problem which is discrete logarithm problem. This system is more secure and efficient since there is no exchange of keys during the protocols of encryption and decryption. Thus, this work tried to use this fact to propose a secure asymmetric image encryption scheme. In this scheme the sender and receiver agree on public parameters, then the scheme begin deal with image using Massey Omura scheme to encrypt it by the sender and then decrypted it by the receiver. The proposed scheme tested using peak signal to noise ratio, and unified average changing intensity to prove that it is fast and has high security.

“…ECC is the asymmetric encryption proposed by Neal Koblitz and Victor S. Miller in 1985. The algorithm of ECC is derived from the elliptic curve [19.] 𝑦 2 = 𝑥 3 + 𝑎𝑥 + 𝑏 where a and b are a positive integer of coefficients from 0 to p. Thus, the value of a and b can be considered by the following constraint 4𝑎 3 + 27𝑏 2 𝑚𝑜𝑑 𝑝 ≠ 0 where𝑝 > 3 [22]- [26].…”

The 3D mesh <span lang="EN-US">(Polygon mesh) model has been widely used in multiple computer technology fields such as computer graphic design and modern 3D animation. 3D mesh repositories were created to support the contribution of many 3D artist-designers and have become an important data source. This research is aimed at introducing asymmetric encryption for a 3D mesh model to improve encryption using elgamal elliptic curve cryptography with Fischer-Yates shuffling. The researchers evaluated the performance of the proposed model using Entropy, mean squared error (MSE), and peak signal noise ratio (PSNR) as evaluation matrices. The results of a decrypted model using our approach with a double-precision floating point showed zero means squared error and infinite value of PSNR</span>.

“…Related work: Like chaotic maps, elliptic curves (ECs) are highly sensitive to the initial parameters, and a number of EC-based algorithms have been developed for cryptographic applications [9,[35][36][37][38][39][40][41][42][43][44][45][46][47][48]. Zhang and Wang [40] used the group law for the generation of a public key and encrypted digital images by combining a chaotic system and elliptic curve cryptography (ECC).…”

A Novel Image Encryption Scheme Based on Elliptic Curves over Finite Rings

Image encryption based on elliptic curves (ECs) is emerging as a new trend in cryptography because it provides high security with a relatively smaller key size when compared with well-known cryptosystems. Recently, it has been shown that the cryptosystems based on ECs over finite rings may provide better security because they require the computational cost for solving the factorization problem and the discrete logarithm problem. Motivated by this fact, we proposed a novel image encryption scheme based on ECs over finite rings. There are three main steps in our scheme, where, in the first step, we mask the plain image using points of an EC over a finite ring. In step two, we create diffusion in the masked image with a mapping from the EC over the finite ring to the EC over the finite field. To create high confusion in the plain text, we generated a substitution box (S-box) based on the ordered EC, which is then used to permute the pixels of the diffused image to obtain a cipher image. With computational experiments, we showed that the proposed cryptosystem has higher security against linear, differential, and statistical attacks than the existing cryptosystems. Furthermore, the average encryption time for color images is lower than other existing schemes.
