Authentication with Distortion Criteria
摘要：
在各种应用中，除了潜在的篡改攻击之外，还需要对经历了合法编辑的内容进行认证。我们制定了一个严格的安全概念的基础上，这个问题，并描述和解释相关的信息理论的性能限制。结果可以被看作是传统认证的经典方法的自然推广。通过进一步将结果专门化到伯努利和高斯情况，获得了对此类系统的结构及其行为的额外见解。相关联的系统被证明是更好的性能和/或安全性方面比通常提倡的方法的基础上的数据隐藏和数字水印。最后，该公式被扩展，以获得有效的分层认证系统的建设。
英文摘要：
In a variety of applications, there is a need to authenticate content that has experienced legitimate editing in addition to potential tampering attacks. We develop one formulation of this problem based on a strict notion of security, and characterize and interpret the associated information-theoretic performance limits. The results can be viewed as a natural generalization of classical approaches to traditional authentication. Additional insights into the structure of such systems and their behavior are obtained by further specializing the results to Bernoulli and Gaussian cases. The associated systems are shown to be substantially better in terms of performance and/or security than commonly advocated approaches based on data hiding and digital watermarking. Finally, the formulation is extended to obtain efficient layered authentication system constructions.
