Abstract

See full text

An information processing device of one embodiment includes a first memory being volatile, a second memory being non-rewritable and nonvolatile, and a processor. A first program, a second program, and a digital signature for the second program are loaded into the first memory. A third program and a public key are stored in the second memory. Upon satisfaction of a certain condition during execution of the first program, the processor verifies the second program on the basis of the digital signature and the public key, in accordance with the third program. After finding a result of the verification as a pass, the processor analyzes the first program in accordance with the second program. The processor refrains from analyzing the first program after finding the result of the verification as a fail.
