Memory controller and method of providing firmware image

A memory controller and a method of providing a firmware image are provided. The memory controller is configured to control a non-volatile memory and includes: an OTP memory configured to store a first public key, the OTP memory being a one-time programmable memory; and a processor configured to, based on a first signature added to a firmware image including a host authentication public key being verified using the first public key, receive a storage command including at least one second public key and a first host authentication signature for the at least one second public key, and storing the at least one second public key in the OTP memory based on the first host authentication signature being verified using the host authentication public key. 提供了存储控制器和提供固件映像的方法。所述存储控制器被配置为控制非易失性存储器并且包括：OTP存储器，所述OTP存储器被配置为存储第一公钥，所述OTP存储器即一次性可编程存储器；以及处理器，所述处理器被配置为，基于被添加到包括主机认证公钥的固件映像的第一签名使用所述第一公钥被验证，来：接收包括至少一个第二公钥和用于所述至少一个第二公钥的第一主机认证签名的存储命令，并且基于所述第一主机认证签名使用所述主机认证公钥被验证，将所述至少一个第二公钥存储在所述OTP存储器中。
