A Cryptographic Approach for Steganography

Blockchain of Signature Material Combining Cryptographic Hash Function and DNA Steganography

An ideal signature material and method, which can be used to prove the authenticity of a physical item and against forgery, should be immune to the fast developments in digital and engineering technologies. Herein, the design of signature material combining cryptographic hash function and DNA steganography is proposed. The encrypting materials are used to construct a series of time-stamped records (blockchain) associated with published hash values, while each DNA-encrypted block is associated with a set of DNA keys. The decrypted DNA information, as digital keys, can be validated through a has…

A New Approach to Enhance Security of Visual Cryptography Using Steganography (VisUS)

Steganography is a process that hides secrete message or secrete hologram or secrete video or secrete image whose mere presence within the source data should be undetectable and use for transmitting secret information over public media. Visual cryptography is a cryptographic technique in which no cryptographic computation is needed at the decryption end and the decryption is performed by the human visual system (HVS). In this paper, both Steganography and visual cryptography have been selected to provide more secure data transmission over the public media with less hazard of computation. This …

CSS中的信息隐藏：一种安全的公钥文本隐写方案

Information Hiding in CSS : A Secure Scheme Text-Steganography using Public Key Cryptosystem

近年来，编程世界已经引入了一种新的程序设计语言来设计网站，它是CSS，可以与HTML一起使用来开发Web界面。而现在，这两种程序设计语言似乎是不可分割的。作为客户端脚本，CSS作为原始脚本对所有用户都是可见的，但它不能被授权更改。网站是全世界信息传播者的工具，这当然可以通过使用CSS作为信息隐藏器来进行秘密通信。提出了一种利用CSS等Web工具进行信息隐藏的新方案。这是一种使用文本隐写术技术的秘密通信机制，该技术将消息嵌入CSS文件中，并使用RSA作为公钥密码算法进行进一步加密。

隐写术：一类具有安全性质的算法

Steganography: a Class of Algorithms having Secure Properties

基于混沌的信息隐藏方法是信息隐藏领域的一个重要研究方向，但目前还没有明确的理论依据。事实上，为什么混沌对于谨慎、鲁棒性或安全性的处理是有用的，很少有人解释。本文提出了一类新的基于Devaney拓扑混沌的有限域迭代的非盲信息隐藏算法。该方法是完全形式化和原因发生的数学理论的混沌解释。最后，隐写安全性和混沌安全性，从而证明了一大类算法。
