| description | To provide a digital failure injection detector.SOLUTION: A secure integrated circuit (IC) has a function circuit and a protection circuit for protecting the function circuit for countering failure injection attack. The protection circuit has a plurality of digital detection cells and a protection logic. The detection cell has corresponding input and output and forms at least one chain with an output and input connection system. A predetermined detection cell in the chain is provided for failure injection attack and drives an input of the succeeding detection cell in the chain and switches (toggles) an output, thereby prevailing a pulse along the chain. The protection logic is provided to receive the pulse from the chain and to activate a counter operation.SELECTED DRAWING: Figure 1
【課題】デジタル故障注入検出器を提供する。【解決手段】セキュア集積回路(ＩＣ)は、機能回路、および、故障注入攻撃に対抗する機能回路を保護する保護回路を有する。保護回路は、複数のデジタル検出セル、および、保護ロジックを有する。検出セルは、対応する入力と出力を有し、且つ、出力入力接続の方式で、少なくとも一つのチェーンを形成する。故障注入攻撃に対応するため、チェーン中の所定の検出セルが設置されて、チェーン中の後続の検出セルの入力を駆動する一出力を切り替え(toggle)、これにより、パルスを、チェーンに沿って伝播させる。保護ロジックが設置されて、チェーンからパルスを受信するとともに、反応動作を起動する。【選択図】図１ |
