  • Method for remotely acquiring secret key, POS terminal and storage medium
    Patent number: 11050555
    Abstract: A method for remotely acquiring secret key, comprising steps of detecting an injection key acquisition instruction; generating a temporary key pair when the injection key acquisition instruction is detected; acquiring a locally stored private key in a random key pair, and using a private key in the random key pair to perform signature on a public key in the temporary key pair to generate a temporary key signature; acquiring a first identity authentication certificate; sending the temporary key signature and the first identity authentication certificate to a remote injection server; receiving an injection key ciphertext signature and a second identity authentication certificate which is returned by the remote injection server according to the temporary key signature and the first identity authentication certificate; and acquiring and storing an injection key according to the injection key ciphertext signature and the second identity authentication certificate.
