Abstract
The invention relates to a key injection method and system and computer equipment. The method comprises the following steps: acquiring a pre-stored post-quantum public key, and determining key packaging information and a first key; sending a key request and key packaging information to a key basic system, so that the key basic system obtains a second key according to the post quantum private key and the key packaging information; acquiring encryption key information transmitted by the key basic system; the encryption key information is obtained by encrypting the controller key by the key basic system according to the second key; and decrypting the encrypted key information through the first key to obtain a controller key, and injecting the controller key into the target controller. The post-quantum key has the characteristic of quantum attack resistance, and the controller key is encrypted by matching the post-quantum key with the first key and the second key, so that the security of the controller key is improved, and the controller key is prevented from being leaked.
