一种安全隐写方案的拓扑研究和李雅普诺夫指数

Topological study and Lyapunov exponent of a secure steganographic scheme

Nicolas Friot, Christophe Guyeux, Jacques M. Bahi

摘要:

CIS2是信息隐藏文献中提出的一种隐写方案,属于同时具有隐写性和拓扑安全性的小类算法。由于其隐写安全性,该方案能够抵抗“仅水印攻击”框架下的攻击。它的拓扑安全性增强了它在Simmons' prisoner problem中抵御其他框架中的已知消息攻击或已知原始攻击的能力。在这项研究工作中,研究的拓扑性质的C I S 2的描述该计划的迭代实数线,并调查其他安全性质的拓扑性质的李雅普诺夫指数。实验结果表明,该方案也能在“估计原始攻击”的情况下撤回恶意攻击者。

英文摘要:

CIS2 is a steganographic scheme proposed in the information hiding literature, belonging into the small category of algorithms being both stego and topologically secure. Due to its stego-security, this scheme is able to face attacks that take place into the "watermark only attack" framework. Its topological security reinforce its capability to face attacks in other frameworks as "known message attack" or "known original attack", in the Simmons' prisoner problem. In this research work, the study of topological properties of C I S 2 is enlarged by describing this scheme as iterations over the real line, and investigating other security properties of topological nature as the Lyapunov exponent. Results show that this scheme is able to withdraw a malicious attacker in the "estimated original attack" context too.
