In this scenario, a robust image encryption technique over open network has grasped a great deal of attention. In this paper to meet this challenge, we have established a new multi-layer robust color image encryption using random matrix affine cipher (RMAC), reality preserving two dimensional ...
仿射密码加密,解密 C++实现仿射密码加密解密以及仿射密码的爆破(C++ implementation of affine cipher encryption and decryption)
encryption function is defined as(where addition is over). The generalized Even-Mansour scheme replaces the key additions with secret affine mappings and breaking it reduces to solving the affine equivalence problem, as originally described in [3]. The best known algorithms for the affine equivalenc...
Due to the linearity of the Hill cipher, it is vulnerable against smaller key spaces. Furthermore, the same weaker secret key is used to generated the self-invertible matrix, and is used for both encryption and decryption. In this work, we examine the security of the scheme in [7] and ...

The proposed cryptosystem includes an encryption algorithm that is an improved variant of the Affine Hill cipher, and two cryptographic protocols that are introduced for the proposed cryptosystem. Copyright 2009 John Wiley & Sons, Ltd.doi:10.1002/sec.137...
EncryptionIn this work, we propose a novel color image encryption scheme based on symmetric keys using the synergistic approach of Arnold transform, 3D logistic chaotic map with XOR operation, and affine hill cipher technique. All these methods work together and generate a strong cipher to abstain...
