白盒密码的设计与研究

Design and Study of White-Box Cryptography

白盒攻击环境指的是密码软件的执行对攻击者完全可见的环境。在白盒攻击环境中,攻击者通过观察或者执行密码软件,很容易就可以获得密钥信息。白盒密码是针对这种环境提出来的,其目的是为了在白盒攻击环境中,有效地防止攻击者获得密钥信息,并介绍了白盒密码的主要设计方法并进行了分析。

White-Box attack context is the setting that the attacker has thorough access to the software implementation; the attacker could acquire the secret keys by observing or implementing the cryptographic software. White-Box cryptography is proposed under these circumstances, which aims at protecting the secret keys in White-Box attack context and preventing the attacker from finding the keys. In this paper, the main idea of how to design a White-Box cryptography is presented, and an analysis of the cryptography also given.
