摘要

针对ChaCha流密码的四分之一轮，提出了两种基于奇偶校验的并发错误检测方案，以防止瞬时错误和永久错误的发生。它们在实现开销和错误覆盖率之间提供了一种权衡。第二种方法可以检测四分频输入/输出和中间信号上的任何奇权误差，而第一种方法需要较少的逻辑。

Parity-Based Concurrent Error Detection Schemes for the ChaCha Stream Cipher

We propose two parity-based concurrent error detection schemes for the Quarterround of the ChaCha stream cipher to protect from transient and permanent faults. They offer a trade-off between implementation overhead and error coverage. The second approach can detect any odd-weight error on the in-/output and intermediate signals of a Quarterround, while the first one requires less logic.
