Publication number: 20150186679Abstract: A secure processor system capable of improving the security of processor processing by the addition of minimum modules without the need for a manufacturer and a user to know encryption information of each other has been disclosed. The secure processor system includes a secure processor having a CPU core that executes a instruction code, an encryption key hold part that holds a processor key, and an encryption processing part that encrypts or decrypts data input/output to/from the core with a processor key and a memory, and the encryption key hold part includes a hardware register that holds a hardwired encryption key, a write only register that stores an encryption key for instruction to be input and holds the stored encryption key for instruction so that it cannot be read, and the encryption key hold part outputs a hardware encryption key as a processor key at the time of activation and outputs a command encryption key as a processor key after a encryption key for instruction is written.Type: ApplicationFiled: February 13, 2015Publication date: July 2, 2015Applicant: FUJITSU SEMICONDUCTOR LIMITEDInventors: Seiji GOTO, Hidenori KOYAMA, Jun KAMADA, Shinya MUKAI, Makoto NAKAHARA, Taiji TAMIYA, Makoto NISHIKATA, Arata NOGUCHI, Chiduka TSURUOKA
