Design and implementation of encryption for programs based on KEELOQ technology

To solve the problem of encryption and attestation in the computer system or application files,a new method to apply the advanced KEELOQ encryption technology is proposed,so as to enhance protection of lawful use of software and system safety.The method adopts the KEELOQ code hopping technology,which can effectively generate the secret key for processing encryption.Besides analyzing the principle and the configuration of the file encrypting,it also makes some suggestions about requirements for the system hardware and software,and gives a realization strategy.The file encryption tests show that this method has two characteristics,one is that its hardware has the ability of more stability and anti-interception,the other is that its software has the ability of flexible interface matching and is much cheaper,thus giving play to the superior KEELOQ technology in the new field.
