Abstract

The invention provides a method for realizing system authentication of an intelligent mobile terminal of a power grid based on a PUF. The method comprises a registering phase and an authenticating phase. The registering phase comprises: generating a seed value S having a fault tolerance function; generating a standard BCH codeword; generating an identification code ID of the slice SRAM; generatinghelp data HD; completing system registration, and starting normal operation of the system. The authenticating phase comprises: reading an identification code NID with noise; reading help data HD; obtaining a BCH code with errors; performing BCH decoding operation on the BCH code with errors; if the actual error is not larger than the designed error correcting tolerance t, generating a BCH code ofn bits standard, and the system authentication is successful; otherwise, the BCH decoding fails, and the program operation ends; if the decoding is successful, recovering the identification code ID used in the registering phase of the system, and completing the authenticating phase of the system, and then starting the normal operation of the system. According to the method for realizing system authentication of an intelligent mobile terminal of a power grid based on a PUF, the PUF is applied to the intelligent mobile terminal of the power grid, so that the safe and reliable system authentication result is achieved.

Description

technical field

[0001] The invention relates to the field of information security, in particular to a method for realizing authentication of a power grid intelligent mobile terminal system based on PUF. Background technique

[0002] In recent years, attacks on power industrial control systems have occurred frequently at home and abroad. Considering the important strategic position of the power industry, once key power facilities are attacked, it will directly affect the safe and stable operation of the power grid and the safety of personal and property, and will directly threaten the development of the national economy. and social stability. The electric power industrial control system is facing a severe security situation, and it is imminent to form a scientific and effective security protection for the electric power industrial control system. Therefore, in the power industrial control system, the smart mobile terminal of the power grid, which is the easiest to be attacke...
