用于保密、隐私和存储的嵌套尾式卷积码（multimedia）---用户6869393

考虑一个密钥协议问题，该问题具有一个生物特征或物理标识符、一个用于密钥登记的终端和一个用于重建的终端。提出了一种嵌套式卷积码设计，该设计在登记时进行矢量量化，在重构时进行误差控制。具有小误码率的物理标识符说明了该设计的优点。嵌套式卷积码的一种变体改进了已知密钥与存储速率的比值，但复杂度较高。具有较低复杂性的第二种变体执行则类似于嵌套极坐标编码。结果表明，密钥与标识符一致的代码的选择主要取决于复杂性约束。

原文题目：Nested Tailbiting Convolutional Codes for Secrecy, Privacy, and Storage

原文：A key agreement problem is considered that has a biometric or physical identifier, a terminal for key enrollment, and a terminal for reconstruction. A nested convolutional code design is proposed that performs vector quantization during enrollment and error control during reconstruction. Physical identifiers with small bit error probability illustrate the gains of the design. One variant of the nested convolutional codes improves on the best known key vs. storage rate ratio but it has high complexity. A second variant with lower complexity performs similar to nested polar codes. The results suggest that the choice of code for key agreement with identifiers depends primarily on the complexity constraint.
