Embodiment Construction

[0033] The present invention will be further explained below in conjunction with the drawings.

[0034] 1. Production of encoder and decoder

[0035] 1.1 Make use of "digital gene code software" (the software has been registered with the National Copyright Administration on August 2, 2007, Guoruan Zhudengzi No. 077526) to make encryption algorithm program modules and decryption algorithm program modules. The method of making encryption algorithm program module is to make the multi-bit switch function of encryption algorithm program (see figure 1 ) Take a series of different values ​​(positive integers), and each value will determine a unique encryption algorithm program module. The decryption algorithm program module directly uses the digital gene decryption algorithm program to enable the multi-bit selection function of the decryption algorithm program (see figure 2 ) Takes different values ​​(positive integers) to correspond to each encryption algorithm program module according...

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 decoderthat 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 metering instruments such as electric meters, water meters, gas meters, heat meters, etc., and belongs to the technical field of data anti-counterfeiting and information security. Background technique [0002] my country's urban water, electricity, and gas three meters charge, and manual meter reading is used to record consumption, which has a history of decades. Using this recording method not only has a large team of meter readers, hard work, and prone to a variety of human errors, but also because the authenticity of the recorded data is difficult to verify, data fraud cannot be avoided. In recent years, problems such as difficulty for meter readers to enter the home (to reach the epitope) have become more and more serious. These circumstances have caused abnormally low water, electricity, and gas...
