PURPOSE:To improve the maintainability of secrecy when this circuit is used for a secret communication since circuit connection information can be considered as an element of a key. CONSTITUTION:Plural dummy random number generating circuits 1 generate data on random numbers in the conditions of respective inputted data. Plural converting circuits 2 convert inputted data into different data. A switching circuit 3 connects the dummy random number generating circuits 1 and converting circuits 2 mutually and optionally according to the given circuit connection information. |
