Abstract

PURPOSE:To produce copyer which can not be decoded, by complicating decoded algorithm, when a decoded key is introduced from a cypher key, by using a communication function. CONSTITUTION:The constitution of the hardware for an encrypter and a decoder is made the same and the operating program is different. Normal sentences U, V, W or cypher sentences X, Y, Z are inputted to an input section 1 having an input register 8 and information is transmitted to an operation section 3 having operation registers 10, 11 in (n+n), (n+1) bits. An auxiliary input section 2 is provided with a fixed constant register 9, and this fixed constant is taken as 7 integers for the cypher key and 6 integers for decode key, the register 10 of the operation section 3 is used for multiplication/division and the register 11 is used for addition/substraction. A tentative storage 4 storing tentatively the result on the way of operation, main storage 5, and tentative storage 4 tentatively storing system program and operation program, are connected to an operation section 3. The sentences X, Y, Z or U, V, W operated at the operation section 3 are outputted from an output section 7.
