Method and device for authenticating terminal as well as EOC (Ethernet over Coax) terminal

Abstract

The invention relates to a method and device for authenticating a terminal as well as an EOC (Ethernet over Coax) terminal. The method for authenticating the terminal comprises the following steps of: acquirement: acquiring characteristic domain information of the EOC terminal and first encryption control domain information which is prestored in the EOC terminal and generated according to a preset key and encryption algorithm based on the characteristic domain information; calculation: generating second encryption control domain information according to the preset key and encryption algorithm based on the characteristic domain information; and authentication: judging whether the first encryption control domain information and the second encryption control domain information accord with the preset authentication passing rule or not, allowing the EOC terminal to pass the authentication if the first encryption control domain information and the second encryption control domain information accord with the authentication passing rule; or otherwise, not allowing the EOC terminal to pass the authentication. The invention can achieve the purpose of carrying out the authentication control on the terminal on the basis of not increasing the terminal cost.

Description

Technical field [0001] The present invention relates to the field of communication technology, and more specifically, to a terminal authentication method and device, and a coaxial Ethernet terminal. Background technique [0002] EOC (Ethernet Over Coax, coaxial Ethernet) is a new technology that has emerged in recent years to achieve two-way network transformation for the existing HFC (Hybrid Fiber Cable) network of radio and television (broadcasting and television). It can be used in existing The radio and television coaxial network can realize the transmission of Ethernet data without network transformation (or network transformation with little workload), and does not affect the existing analog and digital TV CATV (Community Antenna Television) signals Transmission, not to mention the additional arrangement of five-category network cables. [0003] As shown in Table 1 below, there are many specific technical standards for implementing EOC, and they are ultimately for the purpos...

Problems solved by technology

However, for a communication system in its infancy, if the terminal hardware itself is not certified or authenticated, in a relatively closed new system itself, there are no protection measures for the system, and imitation manufacturers are allowed to be short-sighted and counterfeit. The terminal of the manufacturer will undoubtedly have a huge impact on the R&D, production and sales of regular manufacturers, and it is also extremely unfavorable to the development and growth of the new communication system in the embryonic form.
