Zusammenfassung:The invention discloses a method for realizing encryption and decryption through deriving SCKs in Licenses in encryption locks. The method comprises the following steps of: making an encryption lock; when production is required, generating a License file by using software, directly generating an encrypted SCK file of the batch on the basis of the License file, and importing the SCK into a database by using an import tool; when a programming tool carries a unique keyword of a written terminal to initiate an SCK request to the encryption lock, starting an SCK generation algorithm by the encryption lock to generate an SCK by combining permission data in a nonvolatile memory device, encrypting the SCK by using the keyword, feeding the SCK ciphertext back to the programming tool, and writing the SCK ciphertext into a terminal by the programming tool. Through implementing the method, terminals can be directly submitted to operators to be used after being programmed and other files are not required any more. 本发明公开了种
