Embodiment Construction

[0045] In conjunction with the accompanying drawings, below we take the RSA encryption algorithm in the OpenSSL algorithm library loaded on the BBB development board as an example to illustrate the technical solution of the present invention. Such as figure 1 As shown, the process of implementing a side-channel electromagnetic attack is as follows:

[0046] 1. Use the electromagnetic acquisition probe, put the probe on the surface of the working chip, and collect the electromagnetic signal when the chip is working.

[0047] 2. Connect the probe signal to the designed high-frequency electromagnetic signal processing module.

[0048] Figure 4 It is a circuit diagram of a high-frequency electromagnetic signal processing module, which includes a signal amplification circuit and a filter circuit.

[0049] Such as Figure 6 As shown, since the peak-to-peak value of the original electromagnetic wave signal collected is relatively small, the amplified signal multiple is selected ...

Abstract

The invention relates to a high-frequency electromagnetic signal processing module for security assessment of an embedded chip, and belongs to the field of network space security. The method comprisesthe steps of firstly building a signal amplification circuit for performing a side channel electromagnetic attack on password equipment with a high-frequency electromagnetic signal chip; building a filter circuit for performing the side channel electromagnetic attack on the password equipment with the high-frequency electromagnetic signal chip; then using an electromagnetic collection probe, placing the probe on the surface of the chip that is working currently, and collecting an electromagnetic signal when the chip is working; accessing a probe signal into a designed high-frequency electromagnetic signal processing module; and at last, storing the electromagnetic signal processed by the high-frequency electromagnetic signal processing module, and cracking a secret key in a simple energyattack manner. According to the module provided by the invention, extraction of a feature signal in the side channel attack is facilitated; meanwhile, the position of a password algorithm can be intuitively analyzed, so as to help positioning of the embedded equipment and execution of an encryption region of the password algorithm, and provide advantages for the electromagnetic attack.

Description

technical field [0001] The invention relates to a high-frequency electromagnetic signal processing module for safety evaluation of embedded chips, which belongs to the field of network space safety. technical background [0002] As the Internet of Things and mobile Internet enter the lives of the public, its huge market prospect has given birth to another rapid development of embedded devices, and embedded devices also occupy a certain share of Internet of Things and mobile Internet devices. Domestic manufacturers such as Xiaomi, LeTV, and Huawei have launched their own products, hoping to stand out in the wave of "Internet +". Huawei has cooperated with multiple operators to complete smart meter reading and smart parking systems. Companies such as Xiaomi and LeTV have launched TV boxes. Embedded devices usually contain secret information such as user privacy. Since secret information is included, hackers will launch attacks to obtain user secret information and evaluate th...
