Digital television receiving terminal and data secret keeping method and system thereof

Abstract

The invention is applicable to the technical field of digital televisions, providing a digital television receiving terminal and a data securing method and system thereof. The method comprises the following steps: a personal identification number and original random validation characters are obtained, packed and encrypted, thus generating a validation encrypted message; the validation encrypted message is sent to current inserted USB encryption equipment; and the received random validation characters sent back by the current inserted USB encryption equipment are compared and judged, and a starting operation and a shutdown operation are carried out. In the invention, an encryption algorithm of the USB encryption equipment corresponding to the personal identification number is applied for encrypting the personal identification number and the original random validation characters, and the encrypted message is sent to the USB encryption equipment, simultaneously, a comparative judgment of the received random validation characters sent back by the USB encryption equipment and the original random validation characters is carried out, and the starting operation and the shutdown operation are carried out, thus effectively securing the data of a set-top box.

Description

technical field [0001] The invention belongs to the technical field of digital television, and in particular relates to a digital television receiving terminal and a data security method and system thereof. Background technique [0002] With the continuous development of science and technology, people's demand for information security and data confidentiality is increasing. USB encryption devices are playing an increasingly important role in different fields. They are mainly used in bank keys, computer boot locks, In areas such as access control, it mainly protects important core data or acts as a safety switch. [0003] Set-top boxes usually set passwords to ensure that core modules and specific programs are illegally accessed, prevent certain setting items from being illegally changed, such as searching, restoring defaults, etc., and can also prevent certain functional modules from being illegally accessed, such as stocks, video on demand, etc. [0004] However, the passw...
