Zusammenfassung: | The invention relates to the field of computer security, and discloses a firmware import method which comprises the following steps: receiving firmware comprising a first data packet and a second data packet, and importing the first data packet into a read-only memory of a security chip; obtaining a first key from a preset position in the first data packet, and decrypting the second data packet by using the first key to obtain third plaintext data; and writing the third plaintext data into a storage module of the security chip. Therefore, the security of the security chip in the firmware import process is protected.
本申请涉及计算机安全领域,公开了一种固件导入方法,包括:接收包括第一数据包和第二数据包的固件,将第一数据包导入到安全芯片的只读存储器中;从第一数据包中的预设位置处获取第一密钥,并利用第一密钥对第二数据包进行解密,得到第三明文数据;将所述第三明文数据写入到安全芯片的存储模块中。藉此来保护安全芯片在固件导入过程中的安全。 |
