Fig. 3From: Winternitz stack protocols for embedded systems and IoTSecurity parameter \({\textbf {Y}}\) versus oracle size \(\kappa\) for various fabric widths. The dashed line marks the target security: 256 bits (or 128 bits Post Quantum). The target is reached at the following levels of w: 1024: 44, 2048: 36, 4096: 31, 8192: 27Back to article page
