基于神经网络的单向Hash函数

One-way Hash Function Based on Neural Network

Shiguo Lian, Jinsheng Sun, Zhiquan Wang

摘要:

基于三层神经网络构造了一个哈希函数。三层神经元分别实现了数据的混淆、扩散和压缩,并提出了支持变长明文的多块哈希模式。理论分析和实验结果表明,该散列函数是单向的,具有较高的密钥敏感性和明文敏感性,并且能够抵抗生日攻击和中间相遇攻击。另外,神经网络的特性使得并行实现成为可能。这些属性使其成为数据签名或身份验证的合适选择。

英文摘要:

A hash function is constructed based on a three-layer neural network. The three neuron-layers are used to realize data confusion, diffusion and compression respectively, and the multi-block hash mode is presented to support the plaintext with variable length. Theoretical analysis and experimental results show that this hash function is one-way, with high key sensitivity and plaintext sensitivity, and secure against birthday attacks or meet-in-the-middle attacks. Additionally, the neural network's property makes it practical to realize in a parallel way. These properties make it a suitable choice for data signature or authentication.
