Zusammenfassung: | 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. |
