Key Half Life 1.1 -

Version 1.0 of key half-life was simple. It said: After time T, a cryptographic key has a 50% chance of being compromised. That was the era of Moore’s Law as a gentle slope, where attack surfaces were smaller and trust was implicit. But threats don't stand still.

[ P(t, u) = 2^{-t/T} \cdot (1 - e^{-\lambda u}) ] key half life 1.1

In the quiet hum of the data center, where servers breathe recycled air and LEDs blink in endless binary rhythm, a clock is ticking. Not the clock of seconds or minutes, but one measured in decryption attempts, brute-force hashes, and quantum advance warnings. This is the half-life of a key—specifically, Key Half-Life 1.1. Version 1

This is the quiet revolution of 1.1: moving from static security to kinetic security . The half-life is not a warning. It is a design parameter. But threats don't stand still
