摘要
本文提出一种多级密钥固件解锁机制。它通过设备解锁四级密钥和随机字符串来对设备进行安全解锁,能够在确保解锁安全性的基础上,兼顾开发调试和售后服务的特殊需求。实验的结果表明,该方法不仅能有效保证解锁的安全性,还能兼顾开发调试和售后服务过程中,对烧写非签名固件进行调试的特殊需求。
This article proposes a multi-level key firmware unlocking mechanism that securely unlocks devices by unlocking fourth level keys and random strings.It can ensure unlocking security while also meeting the special needs of development,debugging,and after-sales service.The experimental results indicate that this method can not only effectively ensure the security of unlocking,but also meet the special needs of debugging non signed firmware during development,debugging,and after-sales service.
