It is fixed identical, that is to say, not necessarily identical between each first information in this k-1 first information.
Function calculates step S113: secret information and the k-1 first information are substituted into formula secret information=f (k first
Information) calculate k-th of first information；Formula " secret information=f (the k first information) " namely " secret information=f (k-1
A first information, k-th of first information) " because secret information and the k-1 first information are it is known that pass through formula " secret
Information=f (the k-1 first information, k-th of first information) " can calculate k-th of first information.
First information step S114: using the k first information as the multiple first information.
The decomposition of secret information is carried out by function f, so that being no longer between each first information and secret information that decompose
Simple cutting relationship can not seeing at all from the first information and secret especially when f is a kind of nonlinear function
Information has any relationship, so as to obtain fabulous a possibility that hiding, capable of cracking in the first information minimum for secret information.
S230 in preferred information extracting method specifically includes secret information and calculates step S231.
Secret information calculates step S231: the k first information is substituted into formula: secret information=f (the k first information) is counted
Calculate secret information.Secret information=f (the k first information), it is, secret information=f (the k-1 first information, k-th
The first information).Because the k first information is it is known that can calculate secret by " secret information=f (the k first information) "
Information.
