一种安全数字水印方案的李雅普诺夫指数估计

Lyapunov exponent evaluation of a digital watermarking scheme proven to be secure

Jacques M. Bahi, Nicolas Friot, Christophe Guyeux

摘要:

在我们以前的研究中,提出了一种新的基于混沌迭代的数字水印方案。该方案同时具有隐写安全性和拓扑安全性。隐写安全是针对“水印攻击”的攻击,而拓扑安全则是针对其他类型的攻击。它的李雅普诺夫指数在这里评估,量化由该计划产生的混沌。关键词:李雅普诺夫指数;信息隐藏;安全性;混沌迭代;数字水印。

英文摘要:

In our previous researches, a new digital watermarking scheme based on chaotic iterations has been introduced. This scheme was both stego-secure and topologically secure. The stego-security is to face an attacker in the "watermark only attack" category, whereas the topological security concerns other categories of attacks. Its Lyapunov exponent is evaluated here, to quantify the chaos generated by this scheme. Keywords : Lyapunov exponent; Information hiding; Security; Chaotic iterations; Digital Watermarking.
