Abstract
Disclosed is a secure semiconductor chip. The semiconductor chip is, for example, a system-on-chip. The system-on-chip is operated by connecting normal IPs to a processor core included therein via a system bus. A secure bus, which is a hidden bus physically separated from the system bus, is separately provided. Security IPs for performing a security function or handling security data are connected to the secure bus. The secure semiconductor chip can perform required authentication while shifting between a normal mode and a secure mode.
