Device for security attack testing of SPI interface chips and security attack testing method thereof

The invention discloses a device for security attack testing of SPI interface chips and security attack testing method thereof. The device includes a test chip fixture and a fault injection port, an SPI-7816 conversion circuit, a first 7816 communication port, a power supply port, and a tongue plate circuit. The SPI-7816 conversion circuit is used for converting the SPI communication protocol to the 7816 communication protocol for communication. The SPI-7816 conversion circuit is encapsulated inside the metal housing. The power supply port is electrically connected to the SPI-7816 conversion circuit connect to the power supply for supplying power to the SPI-7816 conversion circuit. The tongue plate circuit includes a second 7816 communication port electrically connected to the first 7816communication port. The tongue plate circuit is capable of communicating with the fault injection system. During testing of security attacks on SPI interface chips, communication between SPI interfacechips and fault injection
