Equipment authorization method and device and authorization code generation method and device

The embodiment of the invention provides an equipment authorization method and device and an authorization code generation method and device. The method comprises the steps: detecting an authorization flag bit when an algorithm program is started so as to determine whether the operation authority of the algorithm program is obtained or not; and if it is detected that the operation authority is not obtained at present, analyzing the algorithm program package to obtain the equipment authorization code. Furthermore, the equipment authorization code is encrypted by adopting a preset encryption mode so as to reduce the probability that the Mac address is stolen; the equipment authorization code is decrypted by adopting a preset decryption mode corresponding to the encryption mode to obtain a second Mac address, and the first Mac address of the local machine is read for verification; and if the first Mac address and the second Mac address are the same, verification succeeds, and at the moment, the intelligent devic
