Measurement authentication method based on digital signature

Abstract

The present invention relates to a measuring value authentication method based on digital signatures, which utilizes a password algorithm with identification ability to digitally sign the measuring value of a measuring meter, such as an electricity meter, a water meter, a gas meter, a heat energy meter, etc., and a measuring value electronic authentication system consists of a coder and a decoder that are based on the password algorithm. The coder connected with the measuring meter reads a measuring value and then utilizes an encryption algorithm to realtimely convert the measuring value and the user identity information into a code, that is, a digital signature; whereas the decoder utilizes a decryption algorithm to revert the code back to the corresponding measuring value and the user identity information, that is, a verification digital signature. The basic operation of the measuring value electronic authentication is divided into two steps, the authentication registration and the authentication, wherein the authentication registration is a process in which a service provider registers the code generated by the coder, and the authentication is a process in which the service provider utilizes the decoder to revert the code obtained by the authentication registration back to the corresponding measuring value and the user identity information. Characterized in strong conditionality and simple operation, the present invention eliminates the defect that the authenticity of data is hard to be verified in manual metering.

Description

technical field [0001] The invention relates to a measurement value authentication method based on a digital signature, which is suitable for the measurement value authentication of electric meters, water meters, gas meters, heat meters and other measuring instruments, and belongs to the technical field of data anti-counterfeiting and information security. Background technique [0002] my country's cities and towns charge for water, electricity, and gas with three meters, and manual meter reading is used to record the consumption, which has a history of decades. With this recording method, not only the team of meter readers is huge, the work is hard, and various human errors are prone to occur, but also because the authenticity of the recorded data is difficult to verify, it is unavoidable to avoid data falsification. In recent years, problems such as the difficulty of meter readers entering the household (reaching the meter position) have become more and more serious. Thes...
