Embodiment Construction
[0035] Below in conjunction with specific embodiment, further elaborate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. The embodiment of the present invention relates to a power plant data safe and trusted transmission method with enhanced digital watermarking technology. The specific implementation process is as follows: figure 1 shown, including the following steps:
[0036]Step 1. Data collection: The data collected by the power plant is in the form of a .txt file, and each line is divided into three fields, representing the measurement point code field, time stamp, and load value; where the time stamp is the time value of the measurement point minus 1 in 2001 For the difference formed at 0:00:00 on the 1st of the month, the encoding field is the desensitized data of the name of the power plant, and the sampling frequency is five seconds,...

The invention provides a power plant data safe and credible transmission method for enhancing a digital watermarking technology, and belongs to the field of data safe transmission. In order to solve the problem of information tampering of the power data document in network transmission, an encryption watermark algorithm is introduced into document protection, power transmission data is used as a carrier, and the encryption algorithm is used for carrying out covert communication on the transmission data, so that the data is prevented from being tampered in the transmission process, and the security of the power transmission data is improved. And after the transmission is finished, carrying out identity confirmation by using an encryption algorithm, and verifying whether the document is tampered or not. Simulation experiment results show that the method can effectively protect the data, covert communication is achieved, and the method can be applied to safe transmission of the data in the actual power plant operation process.
Description
technical field [0001] The invention belongs to the field of power plant data storage and transmission, and in particular relates to a safe and credible power plant data transmission method with enhanced digital watermark technology. Background technique [0002] With the rapid development of modern digital technology, as well as its rapid spread and wide application, various digital media, such as images, videos, audios, etc., are becoming more and more common in daily life, bringing many conveniences to people. At the same time, digital media information can be copied without restriction during transmission and application, and digital content is easy to be tampered with unintentionally, intentionally, or even maliciously, which brings potential harm to information holders and users , may cause serious social problems such as economic disputes, legal perjury, and political conflicts. Therefore, the authenticity and integrity authentication of digital media information wil...
