Non interactive anti-exfil (airgap compatible)

However, the effectiveness of this approach is qualified by recognizing that if the checksum remains constant, it doesn't genuinely create a quadratic problem for the attacker but rather introduces a form of hardening with a specified number of iterations (c iterations). The proposal suggests setting a computational target time of approximately 2 seconds for verifying a single signature. This duration is strategically chosen to ensure that any attempt by an attacker to leak more than one bit of information at a time becomes significantly detectable and presumably impractical. The fundamental question raised pertains to identifying any potential flaws or oversights in adopting such a strategy for enhancing security measures.
