Document Type and Number:
Japanese Patent JP6547756
Kind Code:
B2
Abstract:
A security system includes: a first device that includes a first processor and a first target processor; and a second device that includes a second processor and a second target processor. The first processor executes a first process including: first protecting a first program as a monitoring target among programs operating on the first target processor; first decrypting encrypted data obtained by encrypting output data from the first program; and first encrypting the decrypted output data and causing the encrypted data of the output data to be transmitted to the second device.
