class="wp-block-heading"><strong>Ledgerが盗まれた場合、泥棒は暗号資産にアクセスできますか？</strong></h2> <p>いいえ。Ledgerデバイスが盗まれたとしても、泥棒はデバイスにアクセスできません。泥棒にとっての最初の障壁は、LedgerデバイスのPINコードです。</p> <h3 class="wp-block-heading"><strong>LedgerデバイスにはPINコードがあります</strong></h3> <p>Ledgerデバイスのオンボーディング（開始）プロセスを開始すると、PINコードを設定するように求められます。 LedgerデバイスのPINコードは4～8桁で、デバイスのロックを解除してトランザクションに署名するのに必要です。このLedgerのセキュリティモデルの部分により、デバイスを見つけるだけでは誰も暗号資産にアクセスできないことが保証されています。あなた以外の誰もデバイスを使用したり、デバイス上のあらゆるものにアクセスしたりすることはできません。</p> <p>仮に攻撃者があなたのPINコードを推測しようとしたとしても、8桁のコードを正確に推測することがどれほど難しいかご存知ですか？ヒント－その確率はだいたい1億分の1です。</p> <p>さらに、あなたのPINを推測しようとする人は3回しか試行できません。 3回目の試行後、デバイスは自動的にリセットされ、既存のデータがすべて消去されます。詳細は、<a href="https://support.ledger.com/ja/article/360019010273-zd">LedgerのPINコードを変更する方法に関する記事</a>をご覧ください。簡単に言うと、Ledgerを紛失された場合でも、このPINコードによってお持ちの暗号資産へのアクセスは保護されたままです。</p> <h3 class="wp-block-heading"><strong>Ledgerデバイスはセキュアエレメント（SE）チップを搭載</strong></h3> <p>たとえ泥棒がハッカーであっても、Ledgerデバイスは<a href="https://www.ledger.com/ja/academy/security/the-secure-element-whistanding-security-attacks" target="_blank" rel="noreferrer noopener">セキュアエレメント（SE）</a>チップにより、秘密鍵をオフラインで保管できます。このチップは、サイドチャネル攻撃やグリッチ（不具合や脆弱性を利用した不正行為、誤作動）などの無数の物理的ハッキングに対して耐性があります。これらの組み込みのセキュリティ機能により、ハッカーが有益な情報を抽出したり、デバイスに予期せぬ動作をさせたりすることが非常に困難になります。そのため、セキュアエレメント（SE）チップは他の安全な産業でも使用されており、最も一般的には銀行カードやパスポートに使用されています。</p> <p>Ledgerを紛失された場合と同様に、シークレットリカバリーフレーズ（シードフレーズ）を使用して新しいデバイスでアカウントを復元できます。</p> <h2 class="wp-block-heading"><strong>シークレットリカバリーフレーズ（シードフレーズ）を使用して紛失または盗難されたアカウントを復元</strong></h2> <p>Ledgerデバイスを初めてセットアップするときは、24単語のリストを書き留めるよう求められます。これは、<a href="https://www.ledger.com/ja/academy/crypto/what-is-a-recovery-phrase">シークレットリカバリーフレーズ</a>またはシードフレーズとして知られています。これらの単語は、正確かつ順序どおりに書き留めることが重要です。これらはアカウントのマスターキーとして機能し、これまでに作成した（そしてこれから作成する）すべてのアカウントを、一連の単語で復元できるようにします。</p> <p><a href="https://www.ledger.com/ja/academy/hardwarewallet/best-ways-to-protect-your-recovery-phrase">このフレーズを安全に保管している</a>限り、元のデバイスがなくても、シードフレーズを使用するウォレットでアカウントを復元できます。</p> <p>ただし、紛失または盗難に遭ったデバイスに対応するシードフレーズを持っていない場合、暗号資産は実際に失われてしまいます。アカウントを復元するには、シードフレーズを管理することが不可欠です。 </p> <h2 class="wp-block-heading"><strong>ウォレットへのアクセスをバックアップする最良の方法</strong></h2> <p>シードフレーズは、デバイスが紛失または盗難に遭った場合に暗号資産へのアクセスを失わないようにするために実行できる最も重要な手順ですが、別の方法もあります。それは、バックアップの作成です。 </p> <h3 class="wp-block-heading">バックアップデバイスの作成</h3> <p>バックアップ用のLedgerデバイスを使用するのは、紛失や盗難から身を守る最も簡単かつ効果的な方法です。 </p> <p>ご必要なのは、既存のデバイスのシードフレーズを2番目のLedgerデバイスにインポートすることだけで、実質的に複製デバイスを作成できます。デバイスの初期化中に「Restore（復元）」を選択し、既存のウォレットのシードフレーズを入力するだけです。これにより、2台目のデバイス上で既存の暗号資産アカウントがすべて復元されます。この複製はバックアップデバイスになり、どこか安全な場所に保管して、気楽に放置しておくことができます。</p> <p> つまり、仮にメインデバイスを紛失しても、問題ありません。バックアップを取得するだけで、もう安心。何事もなかったかのようにトランザクションできます。</p> <h3 class="wp-block-heading">Ledger Recoverを試す</h3> <p>デバイスなしで暗号資産にアクセスするためのもう1つの方法は、Coincoverが提供するLedger Recoverです。<a href="https://www.ledger.com/ja?post_type=academy&p=295770" target="_blank" rel="noreferrer noopener">Ledger Recover</a>は、有料のオプションサービスで、ウォレットへのアクセスをバックアップする方法をご提供します。本サービスをご利用いただくと、鍵をオフラインに保ちながら、いつでもどこでもウォレットにアクセスできます。</p> <p>Ledger Recoverをご使用いただくと、外出先でもweb3とやり取りするときにセルフカストディ（自己保管・自己管理）のすべての利点を享受でき、IDを使用して暗号資産ウォレットへのアクセスを自由に取得できます。 Ledgerデバイスが紛失または盗難に遭い、シードフレーズがなくなった場合でも、Ledger Recoverをご使用いただくと、アカウントへのアクセスが簡単になります。</p> <h2 class="wp-block-heading"><strong>Ledgerデバイスを紛失しても暗号資産を失うわけではありません</strong></h2> <p>Ledgerデバイスを紛失されましたか？大丈夫です！ Ledgerデバイスを紛失しても、暗号資産が失われるわけではありません！ PINコードにより、他人がそのデバイスを使用することはできません。また、シークレットリカバリーフレーズを使用して新しいデバイスでアカウントを復元できます。誰もあなたの暗号資産にアクセスできません。これこそが、セルフカストディの本質です。</p> <div class="wp-block-image"> <figure class="aligncenter size-large"><a
