A Cost-Effective Private-Key Cryptosystem for Color Image Encryption
نویسندگان
چکیده
This paper presents a cost-effective private-key cryptosystem for color images. The scheme allows for secret sharing of the color image by generating two color shares with dimensions identical to those of the original. Encryption is performed via simple binary operations realized at the image bit-levels altering both the spectral correlation among the RGB color components and the spatial correlation between the neighboring color vectors. The decryption procedure uses both noise-like color shares as the input and recovers the original image with perfect reconstruction.

QTRU: quaternionic version of the NTRU public-key cryptosystems
In this paper we will construct a lattice-based public-key cryptosystem using non-commutative quaternion algebra, and since its lattice does not fully fit within Circular and Convolutional Modular Lattice (CCML), we prove it is arguably more secure than the existing lattice-based cryptosystems such as NTRU. As in NTRU, the proposed public-key cryptosystem relies for its inherent securi...
متن کاملDynamic Key Exchange Method for Image Encryption
In recent years, a variety of image encryption scheme has been proposed. A new color image encryption method based on dynamic key exchange is proposed in this paper. For real time image encryption and lesser amount of time. The algorithm lacks of the characteristic of diffusion because each pixel is operated individually and a chosen/known-plaintext attack can break the scheme. The 192-bit-long...

An increasing demand of secure data transmission over internet leads to the challenge of implementing a consistent cryptosystem. In 2004, USA navy published the patent which highlights the importance of fractal as an encryption/decryption key in a cryptosystem [1]. Fractal possess butterfly effect i.e. sensitivity to initial condition, due to which small change in input produces a major change ...
