Research on Encryption Technology of CAA Software Based on RSA Algorithm and Hardware Information Extraction

CAA software is developed to extend the scope of applications of CATIA, whereas the CAA provides no API to implement the encryption of CAA software, which is to the disadvantage of protecting the security of CAA software and the intellectual property right of developers. This paper proposed an encryption technology of CAA software based on the asymmetric encryption algorithm: RSA, and hardware information extraction, to implement offline and multi-point encryption, with the advantages of rapid encoding and decoding speed, simple authorization, and high security.
