Software authorization method and device and electronic equipment

The embodiment of the invention discloses a software authorization method and device and electronic equipment. The software decryption process and the certificate authorization process can be executed under the security environment (namely a first system), and the security under the security environment is not affected under attacks of the common environment. Meanwhile, the software authorization method comprises two decryption processes, the second decryption process is executed on the condition that certification is passed when both systems are secure, it is ensured that software runs under the authorization permission on the condition that the security of the electronic equipment is ensured, the software cracking difficulty is improved, and the software security is improved.
