对基于置换奇偶机的神经密码的成功攻击

Successful attack on permutation-parity-machine-based neural cryptography

Luís F. Seoane, Andreas Ruttor

摘要:

提出了一种对基于置换奇偶机的密钥交换协议进行概率攻击的算法。该策略不是模仿通信伙伴的同步,而是由蒙特卡罗方法来采样可能的权重空间,在内部回合和分析方法来传达提取的信息从一个外部回合到下一个。结果表明,在攻击下的协议不能比窃听者使用该算法同步更快。

英文摘要:

An algorithm is presented which implements a probabilistic attack on the key-exchange protocol based on permutation parity machines. Instead of imitating the synchronization of the communicating partners, the strategy consists of a Monte Carlo method to sample the space of possible weights during inner rounds and an analytic approach to convey the extracted information from one outer round to the next one. The results show that the protocol under attack fails to synchronize faster than an eavesdropper using this algorithm.
