本文重点讨论了隐写安全中的几个理论问题和原则，并通过分析相应的算法实例，定义了四个安全级别。在理论分析中，讨论了隐写安全性与水印安全性的区别。给出了隐写安全的两个必要条件。在当前的技术条件下，分析了隐蔽和隐蔽的不可否认性，认为隐写术的安全性应依赖于算法开放的密钥保密性。通过明确密钥在隐写中的作用，形式化地给出了理论上安全隐写算法的必要条件。在分析安全实例时，根据隐写分析攻击对隐写系统的访问变量对隐写分析攻击进行了分类，并定义了隐写分析攻击的四个安全级别。安全级别越高，可以抵御的攻击级别就越高。结合当前的技术条件，给出了算法实例，并分析了其数据隐藏过程、安全级别和实际应用需求。索引术语隐写术安全性，Kerckhoofs原理，隐写分析攻击，生成对抗网络，加密域中的可逆数据隐藏。
This paper focuses on several theoretical issues and principles in steganography security, and defines four security levels by analyzing the corresponding algorithm instances. In the theoretical analysis, we discuss the differences between steganography security and watermarking security. The two necessary conditions for the steganography security are obtained. Under the current technology situation, we then analyze the indistinguishability of the cover and stego-cover, and consider that the steganography security should rely on the key secrecy with algorithms open. By specifying the role of key in steganography, the necessary conditions for a secure steganography algorithm in theory are formally presented. When analyzing the security instances, we have classified the steganalysis attacks according to their variable access to the steganography system, and then defined the four security levels. The higher level security one has, the higher level attacks one can resist. We have also presented algorithm instances based on current technical conditions, and analyzed their data hiding process, security level, and practice requirements.
