Title:
A method in a system, an emulator, a debugging system, and a debugging system
Document Type and Number:
Japanese Patent JP6168894
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make it difficult for a third person to acquire information inside a system.SOLUTION: In a debug system 100, a processor core 101 executes an execution code group 105 included in a storage part 104 to be accessed by the processor core 101. Also, an ICE 103 simulates the operation of the processor core 101 which is executing any execution code of the execution code group 105. When receiving a reading request of any address of the storage part 104 to be accessed by the processor core 101 from the ICE 103, a debug I/F control part 102 generates a common key 108 by using the execution code being executed by the processor core 101 in the execution code group 105. Then, the debug I/F control part 102 encrypts read data 109 read from the storage part 104 by using the common key 108, and transmits the encrypted encryption data 110 to the ICE 103.
