“…Several attempts to use ECC for image encryption have been presented in literature. Most recently, the scheme in [40] embeds the pixels of the scrambled image into an elliptic curve to apply ECC, then uses chaos game with DNA for diffusion. SHA-512 of the image was used to generate the initialization of chaotic maps to resist chosen plaintext attacks.…”

Image encryption schemes can be vulnerable to a variety of cryptanalysis attacks. The use of key-dependent dynamic S-boxes has been shown to improve security. Threats of chosen-plaintext and chosen-ciphertext attacks still linger. In this paper, we present an efficient algorithm for constructing secure dynamic S-boxes derived from Henon map. We use the proposed dynamic S-box to construct an image encryption scheme that includes a novel combination of security features to resist chosen-plaintext and chosen-ciphertext attacks. Namely, a hash verification step at the end of the decryption procedure effectively thwarts chosen-ciphertext attacks. The hash also serves as an image dependent initialization for the keystream, which together with using an image dependent S-box resist known-plaintext attacks. Furthermore, encryption keys are protected against cryptanalysis using elliptic curve cryptography (ECC).Therefore, the recovery of secret keys is as hard as the elliptic curve discrete logarithm problem even in the unlikely case of the recovery of the temporary S-box or keystream. Our evaluation of the proposed image encryption scheme reveals that it achieves a higher security standard than existing techniques. Moreover, the proposed scheme is computationally efficient with encryption throughput approaching 60 MB/s. INDEX TERMS chaotic map, elliptic curve cryptography, image encryption, substitution box.

“…This scheme depends on pixel grouping to achieve faster encryption but unfortunately it still consumes many EC point multiplications. In [21], a chaotic system and EC-ElGamal based image encryption scheme is proposed. Firstly, the initial values of the chaotic map are generated using SHA-512, then crossover and EC-ElGamal encryption is used.…”

In this paper, a novel scheme for secure and real time image transmission is introduced. The scheme uses a block-based elliptic curve (BBEC) public key encryption as a first stage of encryption so it solves the key distribution and management problem of symmetric key encryption in an efficient method. Then the security of first stage BBEC encryption is enhanced through a second stage of encryption which XOR the BBEC first stage output with a pseudo random sequence generated by a new designed multi chaotic pseudo random generator STH. It merges Sine, Ten and Henon maps (STH) and so it has five secret control parameters which increase the key space and hence the scheme security against brute force attacks. Both the key of the first stage BBEC image encryption and the control parameters of the second stage STH depend on two parts: EC Diffie-Hellman shared secret key and the input plain image itself which provides a good randomness and achieves a strong resistance against chosen plaintext attacks. After the two stages of encryption, the encrypted image is digitally signed in an efficient method to achieve integrity, authentication and non-repudiation. The results prove that the proposed scheme is more secure and faster than some other recent EC based schemes. It has low correlation, huge key space; key-dependent pixel value replacement and can resist statistical, differential and noise attacks.

In cryptography, the security is depending on the way in which it produces different ciphertexts for the same plaintext so that the eavesdropper is not able to recover the plaintext from the ciphertext. Though, several block cipher modes viz., CBC, CFB and OFB exist, they take more time for producing different ciphertext blocks for the same plaintext block. To avoid this, an encoding is performed at the plaintext level. There are several encoding schemes like ASCII, Magic Square, and Magic Rectangle based encoding exist in the literature. But, in this paper, a novel encoding technique based on Elliptic Curve, Lucas number, Spiral Clockwise Rotation and Zigzag transformations called ECLUSRZ has been proposed. As, the original form of plaintext is completely altered using this proposed encoding scheme, the eavesdropper may not easily recover the plaintext from the ciphertext. Once, the encoding is performed , the encoded numeral called intermediate plaintext is then used for any one of the public key cryptosystems like ElGamal and the security level produced by ElGamal encryption with ASCII based and the proposed ECLUSRZ based encoding is analyzed.
