Embodiment Construction
[0014] In order to overcome the super password leakage problem existing in the prior art, the present invention designs a dynamic password control method. This method still adopts the mode of super password to help the user, but no longer uses the mode of fixed super password, but adopts an encryption algorithm, and randomly inputs the date of the day and the serial number of the set-top box to calculate and generate a super password. Then input the super password, the date of the day and the serial number of the set-top box into the set-top box to obtain an encryption algorithm. As long as the algorithm is consistent with the algorithm set inside the set-top box, it can help the user to retrieve the initial password.
[0015] The method that the present invention proposes comprises the following steps:
[0016] a. An encryption algorithm F is set in the equipment / software, and the encryption algorithm takes the characteristic value and date of the equipment as variables;
