In computer based data security systems which involve entity authenticating or document time stamping or other cases where data is to be derived from a previous state, the necessary linking values are calculated using recursive chaos based equations such as the type used in fractal theory (the Mandelbrot set) or the Lorentz attractor or other similar approaches. In each case a value in each step is calculated using these equations so that each authentication or timestamp or other data derivation is linked to the previous one in a chaotic way. This makes it impossible to calculate any one value in the link series without having the previous value, due to the chaos aspect thereby enhancing security.
