Stage: PROBLEM TO BE SOLVED: To provide a semiconductor device which satisfies both safety and security requirements and provide a changeover method.SOLUTION: A semiconductor device comprises a safety processor, memories, and a secure computational module. The secure computational module comprises a secure processor, a first and a second ciphering units, and a first and a second data transfer units. The first ciphering unit and the first data transfer unit provide a first ciphering data processing system, and the second ciphering unit and the second data transfer unit provide a second ciphering data processing system. The semiconductor device comprises a switch, and the secure computational module further comprises a selector circuit to selectively connect/separate the first and the second ciphering units. In a first mode, the first and the second ciphering data processing systems are separated and can be operated independently of each other, and in a second mode, both systems are combined and can be simultaneously operated to provide hardware redundancy.SELECTED DRAWING: Figure 3 (Grant)
