Design and Implementation of an Online Power Analysis Attack Platform for HMAC Based on SM3

A method for an online power analysis attack platform against SM3-based HMAC was proposed in the paper. The method adopts a front-end and back-end approach. The front-end implements functions such as uploading power traces, displaying power traces, and inputting power analysis attack parameters. The back-end completes correlation power analysis attack based on the power traces and attack parameters uploaded by the front-end, and returns the attack results to the front-end for display. This design fully utilizes the powerful computing capabilities of the backend server, while also supporting the simultaneous use of multiple detecting users. It has broad application prospects and promotion value.
