Patent JP-H04184629-A (JP)
Title: Electronic computer
Inventor: OE IWAO
IPC: G06F21/12
Filed: 1990-11-20
Abstract: PURPOSE:To prevent the copy and the surreptious use of the computing result by writing this result in a main storage after ciphering it by a ciphering device. CONSTITUTION:A CPU 11 reads a ciphered instruction 'B8' of an address 1000 included in a ciphered machine word program 24. Then a decoding device 9 converts the instruction 'B8' into an instruction '11' of an address 1000 included in a machine word program 23. Thus the CPU 11 performs an internal arithmetic operation. The instruction '11' is identical with 'Push r<l>', therefore the value of a register r1' is ciphered by a ciphering device 8 and written in a main storage 2. When such instructions as a comparison instruction, a branch instruction that require no writing operation are carried out, only the device 9 works in a reading state and the device 8 does not work.
