INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND COMPUTER PROGRAM

摘要

PROBLEM TO BE SOLVED: To make it difficult to perform dynamic analysis of software using a debugger.SOLUTION: An information processing method includes: a monitoring step (S3) in which an arithmetic processing unit that executes a computer program including a key generation part, an encryption processing part, a monitoring part, and a monitoring target part calculates a detection value by using an execution code of the monitoring object part; a key generation step (S5) in which the arithmetic processing unit generates a key by using the detection value which is calculated by the monitoring step; and an encryption processing step (S7) in which the arithmetic processing unit executes encryption processing by using the key which is generated by the key generation step.SELECTED DRAWING: Figure 2
