Asymmetric, multilevel, switchable, and reversible encryption is realized by algorithm encryption, which plays an important role in encryption technology. Fluorescence lifetime encryption is currently not executed by an algorithm. It is well-known that the short fluorescence lifetime (τ1), long fluorescence lifetime (τ2), amplitude-weighted average fluorescence lifetime (τm), and intensity-weighted average fluorescence lifetime (τi) can be obtained using a double exponential fitting, and then these four lifetime parameters can be considered as four lifetime algorithms. Therefore, we propose that the acquisition of these four fluorescence lifetimes can be regarded as further dividing the lifetime by different algorithms and optimizing lifetime multiplexing. Moreover, the four lifetime algorithms of τ1, τm, τ2, and τi can be switched between each other and can be used to perform asymmetric, multilevel, and reversible lifetime encryption to effectively increase the difficulties of anticounterfeiting.
通过算法加密实现了非对称、多级、可切换和可逆加密，这在加密技术中起着重要作用。荧光寿命加密目前不是通过算法执行的。众所周知，使用双指数拟合可以获得短荧光寿命（τ1）、长荧光寿命（τ2）、幅度加权平均荧光寿命（τm）和强度加权平均荧光寿命（τi），然后这四个寿命参数可以被视为四种寿命算法。因此，我们提出获取这四个荧光寿命可以被视为通过不同算法进一步划分寿命并优化寿命复用。此外，τ1、τm、τ2和τi这四种寿命算法可以相互切换，并可用于执行非对称、多级和可逆的寿命加密，以有效增加防伪难度。
