| description | The invention discloses a method for conducting early alarming against side-channel attack in a security chip. The technical problem to be solved is the early alarming against the side-channel attack in the security chip. The technical proposal aims at designing a side-channel attack early alarming module comprising a reset inhibition unit, a counting unit, an alarming unit and a spot protection and restoration unit; the side-channel attack early alarming module is integrated into the security chip and still in active status after being electrically reset on the security chip; and a ratio of the security chip suffering from the side-channel attack is periodically calculated and output. The method can determine the ratio of the security chip suffering from the side-channel attack, and is suitable for various side-channel attacks. And the side-channel attack early alarming module per se has very high security performance. |
