Title:
TERMINAL ANTI-TAMPER DETECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/082730
Kind Code:
A1
Abstract:
A terminal anti-tamper detection method and an apparatus, in the field of information security. The method comprises: a security processing system generating a dynamic signal, outputting the dynamic signal via a self-destruct line output terminal, and receiving a signal via a self-destruct line input terminal (Step S1); the security processing system performing comparison of the signal received via the self-destruct line input terminal and the dynamic signal output via the self-destruct line output terminal, obtaining a comparison result (Step S2); the security processing system determining whether the comparison result meets a self-destruct trigger condition, the self-destruct line being triggered if so, and if not, the self-destruct line not being triggered (Step S3). The present method, by means of using dynamic MESH line anti-tamper technology, can accurately detect a triggering situation, making sure that a protected product immediately acts when unauthorized tampering occurs, ensuring that sensitive information of an individual is not leaked.
