Method and system for evaluating anti-side channel attack capability of USIM (Universal Subscriber Identity Module) card

Abstract

The invention discloses a method and a system for evaluating the side channel attack resistance of a USIM (Universal Subscriber Identity Module) card, and the method comprises the steps: carrying out the interaction between a side channel attack device and the USIM card, and obtaining the energy trace information when the USIM card is attacked; energy trace information generated when the USIM card is attacked by the channel attack equipment is converted into an intuitive energy trace curve through the oscilloscope, and the intuitive energy trace curve is collected to obtain the energy trace curve; carrying out resampling, low-pass and alignment processing on the energy trace curve, and calculating to obtain a key Key and an OPC of the USIM card; and authenticating and verifying the key Key and the OPC, and if verification is correct, indicating that the USIM card is not strong in side channel attack resistance. According to the method, whether the USIM card has the capability of resisting the side channel attack or not is judged by evaluating the energy trace information generated when the USIM card is attacked by the side channel, so that the complexity of evaluating the side channel resisting process of the USIM card is greatly reduced.

AI Technical Summary

Benefits of technology

This patented technology helps evaluate how well a specific type of device called UICM cards can resist being hackled from other devices like USB tokens or wireless networks without having them become vulnerable over time due to attacks on these types of interfaces. It involves comparing different versions of this data for certain characteristics such as power consumption levels (power), frequency response patterns, etc., which are used during testing. By doing this, we aim to identify weaknesses in their ability to protect against various threats.

Problems solved by technology

This patented technical problem addressed by the patents describes how to assess if two different types of attacks against a specific type of smartcard called UICC Card are possible: One involves trying to guess what another person has been given their phone number without actually having them present themselves at home while they use these cards - known as Side Channel Attacking Criterion ("SCAC"). Another threat comes from simulating other people sending similar signals over wireless networks like WiFi. These challengings require evaluation of both sides of the secure connection between the chip embedded within the device itself and the external world.
