摘要
文中提出一种利用指纹生物特征进行密钥封装的方案。使用主成分分析方法对采集的指纹特征数据进行处理。采用Reed—Solomon编码和Hadamard编码的级联方案,随机选取一个密钥应用该级联方案进行编码,把编码后的结果与指纹生物特征生成的secure vault存储在智能卡上,并将随机密钥销毁。在验证阶段,利用相同的指纹特征将该随机密钥重构出来,以应用到其他方面。最后对方案的安全性进行分析。
This paper proposes a key encapsulation scheme with fingerprint biometric. The fingerprint data is processed by the principal component analysis method. The cascaded solution of Reed-Solomon codes and Hadamard codes is used to encode with a random key, then the encoded result and the fingerprint data are integrated to generate the secure vault, which is stored on a smart card, and then this random key is destroyed. During the validation phrase, the random key is reconstructed from the same fingerprint. Finally, the security of this scheme is analyzed.
