A quarter century ago Chor, Fiat, and Naor proposed mathematical models for revealing a source of illegal redistribution of digital content (tracing traitors) in the broadcast encryption framework, including the following two combinatorial models: nonbinary IPP codes, based on an (n, n)-threshold secret sharing scheme, and IPP set systems, based on the general (w, n)-threshold secret sharing scheme. We propose a new scheme combining the main ideas of nonbinary IPP codes and IPP set systems, which can also be considered as a generalization of nonbinary IPP codes to the case of constant-weight codes. In the simplest case of a coalition of size two, we compare the new scheme with previously known ones.

IPP代码和IPP集系统的通用化

25年前,Chor,Fiat和Naor提出了数学模型,用于揭示广播加密框架中数字内容的非法重新分发(追踪叛徒)的来源,包括以下两种组合模型:基于(n, n)阈值秘密共享方案和IPP设置系统,基于通用(w,n)-阈值秘密共享方案。我们提出了一种结合非二进制IPP代码和IPP集合系统的主要思想的新方案,也可以将其视为非二进制IPP代码对恒权代码的推广。在规模为2的联盟的最简单情况下,我们将新方案与先前已知的方案进行了比较。
