认证树奇偶校验机器密钥交换

Authenticated tree parity machine key exchange

Markus Volkmer, André Schaumburg

摘要:

树奇偶校验机(TPM)的同步,已被证明提供了一个有价值的替代概念,安全的对称密钥交换。然而,从密码学家的角度来看,身份验证至少与密钥的安全交换一样重要。例如,通过散列添加身份验证是简单的,但与神经密码学无关。因此,我们制定了一个认证的密钥交换在这个概念。另一种替代方案,将零知识协议的同步,也提出了。因此,可以避免基于使用相同结构的TPM和同步的中间人攻击甚至所有当前已知的攻击。这反过来又对在重量空间中使用轨迹产生实际影响。这两种建议都有一个优点,那就是完全不影响先前观察到的这个相互作用系统的物理特性。

英文摘要:

The synchronisation of Tree Parity Machines (TPMs), has proven to provide a valuable alternative concept for secure symmetric key exchange. Yet, from a cryptographer's point of view, authentication is at least as important as a secure exchange of keys. Adding an authentication via hashing e.g. is straightforward but with no relation to Neural Cryptography. We consequently formulate an authenticated key exchange within this concept. Another alternative, integrating a Zero-Knowledge protocol into the synchronisation, is also presented. A Man-In-The-Middle attack and even all currently known attacks, that are based on using identically structured TPMs and synchronisation as well, can so be averted. This in turn has practical consequences on using the trajectory in weight space. Both suggestions have the advantage of not affecting the previously observed physics of this interacting system at all.
